- I couldn't resist! Once the so-called "cold welding" videos went up, and everyone started messaging us about it, I had to go buy one to figure out what the real deal is behind cold welding. Is it real or is it just someone clicking a switch for an inch? Let's find out! #ColdWelding #ColdTIG #ColdWeld

What's with the nails? Really... WTF is with the nails? I can't watch this because of your nails!!
The fact is - you saw the nails which means you'll recognize those nails when someone tries to steal this video to promote their product (watch the vid if you don't understand).
Yes. I also have a daughter. If she wants to do my nails or put makeup on my face (which she has in the past), I'll totally sit still and become beautiful. She actually would have done better on my nails than I did for this vid.
If a black marker on someone's nails ruined your day - you have some serious issues 🤣. I appreciate the views either way.
that's ingenious!
You’re pretty! Stop it!
You can have custom fingernail decals made with your logo or (ie stolen from) and restrict access to you and your sproutlettes. Sign me 'Father of ALL sproutlettes and Papa of mostly grandsproutlettes'...
i figured you made your nails looks so igly that no one would want to steel it
Now my YT ads are about nail health products! Thanks....
Watching this vid in a pitch black room is like being flashbanged non stop
Fr
It’s all flash and no bang
lol

@@azligckshibson870 why?
This machine is the equivalent of cooking a chicken at 1240° C for 15 seconds
that was actually a pretty cool way to compare it to something respect+
You mean ppl don't do that?
Isn't that 'Cajun Style'? I've always called it 'burnt & raw' but that's just me....
That's why my kfc is so dry....😆
Yeah, then the best meat would be the one between the outer carbonized skin, and the inner frozen tissue.
I own 2 miller tig welders & a multimatic 220/ac/dc & a Lincoln mig w/spool gun....I bought an Andeli cold tig welder for $450. Came with 2 torches (wp-9 & wp-17) plus a simple trigger foot switch. For the specific type of low load stress, high precision tiny parts I make it is fantastic. Limited application for sure, but its incredibly easy to use & fully programmable in microseconds dwell, amperage, cycle(in pulse mode), preflow & postflow. Fantastic for precise tacks that are followed up with silver brazing, short burst spot locks things in place without oxidation & fluxed silver brazing flows beautifully over it. I regularly use it for very thin guage stainless sheetmetal parts as well & never burn through... All you do is regulate your trigger finger timing (or set simply set it to pulse mode) & you can get perfect weld penetration. I see so much hate in comments sections I really don't get it. (*Except it is made in China...& there is an irrational hatred of their products & manufacturing capabilities)
Good review on this I have been picking up a lot of kitchen stainless jobs and was looking at this machine myself!!
Agreed,its for a purpose,not building aeroplanes and as Flatbob says it works well.
My Unimig Razor 200 acdc tig has a spot function which does exactly the same thing,its not new,just another option for your particular circumstance
I'm happy to have watched your testing of this "welding" process. You have proven what I suspected. I have no problem with the nails. Thanks for posting!
Nothing like a narcissist looking for a way to make some money ....which at 1,604,514 views ....he is doing.
This guy is a clown. The nails is evidence of this.
But as far as really understanding the concept of APPLICATIONS ....he really doesn't get it.
I note he mentioned NOTHING about AUTOGENOUS WELDING .....which is what he was doing, almost throughout .....and very little mentioned about weld strength, prepping, or penetration.
I also note it took him up to the half-way point to start talking about "PULSE" ....which is exactly what this is all about.
If you take the heat source away, ....the material cools. It is NO LONGER HOT AND MOLTEN .....MEANING IT IS NOW "COLD".
But if you turn the audio off, you can SEE some interest welding APPLICATIONS going on .....which the audio portion is a god-awful distraction.
.
It's wintertime here. My workshop is not heated.
All my welders are cold welders.
Ah rather you're the cold welder.
Best comment 😂
Hilarious
What model welders?
@@deankendell6644 No, certainly not. None of them are models.
Imo, "cold welding" is just a gimic! I was doing this 35 years ago. I had a spring loaded on/off micro switch taped to my tig torch, and I would either preset my amperage or use the pedal. The switch would completely break the arc/amperage. I referred to the process as manual pulse.
spot on mate so did i been air craft approved for over 20 years and asmi 9 and 6 g app
What do you mean by gimic?
Yeah - I'm not professional but I used to make some custom decorative pannes that had NOT to twist or buckle so I just used to pulse the trigger on the TIG welder.
So there was nothing cold about it - only it did not allow time for heat to build up and the metal could dissipate the heat.
It's not comparable because because here it's electronically controlled at high amperage and very short duration that's perfectly timed. You can't achieve that manually. It's like cleaning fuel injectors with a homemade switch that ruins the injectors vs. a designated device that opens them for a split second just like the car ECU.
@@anancapcat4221 Also known as bullshit.
The “spacey spaciousness” footnote to the Cold Weld definition made me a fan for life. Well done.
"Honey, they didn't have any of the long rolls of aluminum foil at the store." "Hold my beer!"
Is this not pulse welding or arc welding? Is cold welding a new name for it?
@@democracyforall this is not real cold welding. Real cold welding does not use any heat.
totally going to steel/ borrow the "hold my beer" thing for Aloonium foil "cold welding BS"!! (bringin back Bugs Bunnies pronunciation of Aloonium)
Hahaha this is gold!
Haha very funny...😁😆
The Chinese people sure DO understand the word "copyright".
It's the right to copy. 😎
Forced Technology Transfer is an interesting arrangement. They will manufacture stuff for you cheap, so long as you sign over your Intellectual Property to the CCP. Then, everyone (Chinese Manufacturer) is free to copy the other. That's the deal. Its completely transparent. Take it or leave it.
😂
It’s a copy? Right!
Well, I've seen "consumption rights" used around when they were trying to say "consumer rights". I can just hope that is a translation mistake and they actually know the difference...
You need left copy also
I found it quite useful for mixing small items. A/C pipe leaks, for example. Leaks are small, pipes are copper, valves are close by.
i use oxyace for ac leaks, first get qualified guy to empty it, weld it and have same guy fill it. Heck i need to qualify in those too im plumber and i only can install the systems but not fill them or mess with them
Would also be useful for figurine artists
RIP to the people watching this at night lol
🤣🤣
I want one! But then again I never needed a backhoe until bought one. Holes all over the place!
😆
I agree, I didn't know I needed sticks of dynamite untill i didn't have them any more.
Haha. This is the best comment on the internet
Same
Don't put them in your back. Can you dig it man?
I could see this for a jeweler. Neckless, bracelets, etc. Even setting stones. Or if you wanted a second machine to tac sheet metal without fear of melting.
Or maybe prototypes so you can break welds quickly with less loss
Jewelry, and also chainmail!
Eric bloody good idea
Or metal frame eyeglasses (or sunglasses) repair.
Yup, i wonder if it could weld (or rather join) thin silver (0.5-0.8mm) plates?
You can buy a version without the gas and various amounts of capacitors missing for 60 bucks sold as a jewelry welder I have one works okay once you put in the capacitors.
If you want to look into it I have pretty much all the videos in a playlist on my channel and I made a video about modifying them myself, but it's not really informative.
I know I'm pretty late to the party on this one, but I thought up a challenge for you with the cold welding. Produce a satisfactorily strong weld with tubing and show us what it took to pull it off, or how much you had to put into it before ultimately deciding it's not possible. Keep in mind that I haven't spent more than maybe 3 minutes searching before deciding I had an original idea so forgive me if it's already been suggested or done, haha.
I've been a Blacksmith for over 60 years had black nails many a time, like your vids learn new things everyday never to old to learn TKS God Bless you and your daughter
That chick is a pretty good welder, but needs to take better care of her nails.
JSBIRD69 Amen! LOLOLOLOL!
Those finger nails are really freaky. That is a man right ?
@@guysview I don't know now, I have got so many mixed messages, badly chipped nail polish, the relative size of the fingers?
didn't know sharpie were doing nail varnish these days
hers? hehehe it can be both gender who can wear it, call it gothic fingernails. :)
I never seen any one weld aluminum foil together before. That was kinda cool. Cold weld could be termed as a Hobby craft welder
We used to do that in tig class. Its good practice for heat control.
exactly how we practiced as well learning tig!
This isn’t actual cold welding. It’s just low amp tac welding.
learned that trick way back in 1985 the trick is, bet ppl and tell them they can set up the machine ac or dc +/- any amperage there choice and you will weld it i must have made $1000s of dollars since trade school.
Amen brother, Amen
The arc sounds like the old miller snap start which works very well. Super for small tacks.
thanks for making this consumer oriented video. I was very interested in COLD welding until seeing this. Much Love!
One summer while building demolition derby cars, my cousin had laid a weld but the machine wasn’t set right. I told him the weld looked cold so the dipshit touched it 😂. He said “no! That’s hot af!”
lmfao !!!!!
Well hell remember that one for sure next time someone tells him his welds are too cold😂
ROFLMAO.
You can wear gloves. An apron boots all the protection equipment and that shits still going into your shoes.
You see a guy welding he stops and starts hopping around you know wtf he did.
@@bobbg9041 exercise
Roflmao
I'm glad someone took the time and money to look into this!
We need him to do a follow-up video showing how this can be accomplished with a mts 252 or 275 pluse DC TIG welder
@@772777777777777 yes i need this is video
@@billelnaruto5390 mr tack....can you follow up this video...
I watched a few cold welding video... and observed a few things for thin gauge mild steel ie .035
The setteting are preflow
Ramp 0 tig base amp equal sheet thickness ie 35 amps..tig base on time is low..20-50%, freq pluse is equal to amps ie 35 pps, tig base % amps is set low? No down slope...tig end is very low, pre flow 3 sec
I would experiment more but got not argon to play with st this time.
Just look into tool and die (injection molds) repair business. Example: SANWA SW-V01 machine.
This would be great for putting together thicker electronic stuff, as a slightly faster alternative to soldering. Just blast the wires with the arc, then flow solder on. But then again we have bigger solder guns and torches just for that. Maybe making metal jewelry or sculptures where the thinness of the weld is actually desirable?
HAHA, When i first watched this finger nail and "sparking" welding , reminded me of the Mrs.welding youtube channel bragging of "cold welding" lol.. But you do it so much better. .lol Good job..
Looks like someone was reliving highschool with NiN, Marylin Manson, and Lincoln Park. I havent seen nails sharpied black that poorly since I did it in the lunch room bored af. Love it. I'ma go cry to some Dashboard now...
Finally a way to recycle all my odds and ends of aluminum foil.
I noticed that Ms. Weld’s eyelids are special. She uses them to block out the dangerous arc flashes. She really is amazing
As someone who is very very average with welding I watch video's to try and improve my lack of skills. Having said that I have welded 3,000lt water tanks that held together primarily due to doing back over any bad welds with more wire and accepting I had to do it repeatedly to make up for lack of education. I love watching a true craftsman or woman explain while doing and the explanation usually makes me feel a whole lot better. Loved the vid and the nails made me go WTF then figured you had a daughter. I remember similar activities with my oldest who is now 19.
As a matter of fact, it is actually legitimate process that my Kemppi Masterig MLS also has_ _but its called microtack.
And it is meant for tacking very thin parts without penetration, without the need of grinding tacks, need for purge gas and so on.
Are u using shielding gas for the cold welding?
@@ianmoore525 Shielding only one side like regular Tig welding, tack welds only, so there is no full penetration, thus no need for back- purging.
Main downside is, ideal fitment- absolutely no gaps allowed.
@@hdjawa You need to figure out how to feed filler wire in, to close the gaps and add thickness. I think it's better with gas. Argon.
I came for the video, I got the popcorn for the nail comments. :)
I can't find a single negative fingernail comment.
As an old school Coded Welder in ZA i do appreciate your Videos so Much cause at 71 Years of age still Welding everyday of my life i have no rye Bries for anything Chinese !! In Fact i don't understand why i were not Born in USA ! Keep up the Good Work , GOD BLESS
Only a 30 seconds In to the video and I'm realizing that this is the video that explains the other video I had just watched the "Mr.Tack" was a nice touch hahaha I like your humour
We use a "cold welder" professionally. It's a professional machine, somewhere in the 15.000 Dollar-range. This machine is used to tack up woven wire meshes with wires for high-temperature fuel cells (SOFCs). Other possible applications would be jewellery or micro-parts. So yes, there is a field of applicaton for these machines and yes, they work really well. But, almost nobody needs a machine like this at home. I really like the way you pointed out the "cold welds" it produces and yes, on homegamer-sized parts this will mostly be the case. I this it was This Old Tony who showed, that the HTP 221 has a "spot" option for tacking small parts AND it is a fully sized AC/DC TIG-welder. So, if someone had to deal with such situations, that's the go-to machine for the homegamer and also for the fabricator.
The machine in this video can be also used as a normal dc tig welder btw
$15,000?
Or do you measure tenths of a penny...?
@@sourbrothers73 15000 :) That "." vs. "," thing always bothers me. Even though I regularly work with people from over the pond, I get confused with it every time.
@@Gerhardter lmao just ball busting
Lmao did you buy it from "I saw you coming" welding supplies
That thing would keep your auto darken helmet scrambling to keep up. Kind of a war of micro seconds you might say.
If there was a way for the trigger to also trigger the darkening you basically wouldnt see anything going on, just metal fusing since the darkening is so short and the arc so short
@Todd B In a serious setup you're looking through a 10X stereo microscope and it has an automatic shutter to protect your eyes. They are very sweet to use. You can hold small pieces with your fingers next to the joint- THAT'S why they call it "cold welding". You can run along about one hit per second.
@@craigwall9536 Could you elaborate on this, please? Your comment has well and truly caught my interest, sir.
You can set a delay on most helmets, so it can stay dark for 5 or more seconds.
I have Optrel Crystal 2.0, it does not triger when trying out "cold welding"
This looks great for tacking thin body panel sheet metal together for minimum distortion. Not many professional “Welders” that I have encountered seem to understand just how easily you can destroy a panel with too much heat and excessive warpage. Looks better than most factory spot welds that already hold a car body together.
A nice, precise and short tutorial. Thankyou for your time and expertise.
“there’s nothing funny about molten metal so don’t be a dumbass” earned you an instasub. 😂
Now I understand the welds on the cheap Chinese motorcycle mufflers
This looks like more work than doing it the right way lol
@@Mrfitrider1 But you don't need professional to do it. You give welder to a kid, and pay him dish of rice a week.
Dude this guy just doesn't have a clue what he's doing with a tig welder lol
@@craigelkin53 So, he faked it until he made it....hehehe....Seriously, I think he has quite a few clues.
I bought a Grom with a Chinese exhaust, and it broke right in half on a weld like these. Found the pieces, and could tell there was so little penetration, you basically could've painted on the "bead."
I was watching this at midnight and was getting flashbanged on repeat. My eyes want mercy
Yay, somebody has actually bloody explained this (finally hit the bottom of this sodding rabbit hole) so cheers for that...oh and you even cleared up the nail business also...double kudos sir.👍👍
I had a minor moment of panic when you ran your finger across those razor blades
He's forming a BAD habit.
It's those black finger nails.. They Just makes people want to hurt themselves
Don't worry, he lives on the edge.
A tig welder for people who can't weld, was my first impression
That's what I see. Just a series of tacks that aren't properly fusing with the base material.
@@Pleebian94 Imagine if you could do it at 400 or 500 amps. May be able to tack weld 1/8" haha
Been waiting for an english speaker to review one of those things...
@@andrewsturgess2033 at that point the torch to be used will more expensive than the welder LOL
A lot of tig welders can't even weld. Not that they can't weld but hand them a stick welder or a wire feed. Moste can weld with it but it looks like crap.
The "compression cold weld" you described is similar to "space weld". The idea is that any metal in an oxygen atmosphere forms an oxide layer. This prevents metal-to-metal contact from "cold fusing" together. In space, if you have metal that ISN'T oxidized, touch other metal that ALSO isn't oxidized, yes, they can stick. Sometimes really well. Basically, the physics of it is that metal atoms aren't glued" together, they just stick naturally. So when you touch metal to metal, it becomes one bigger piece of metal. The oxide being there is the only reason metals don't stick to each other on earth. "Compression cold weld" forces the metals to mingle by pressing them very hard together. The oxide is still there, but it's getting shoved around, piled together, and pushed out of the way, leading to SOME metal-on-metal contact, and fusion. It's not as strong as a solid piece of metal because there's still some "diluted" oxide in there, but it's pretty strong.
There's also "friction welding", but that's not cold. It IS fun to watch though!
The big problem I see with this cold welding though is simply you are robbing material to fill in gaps, and that's why the welds are weak. Seeing these areas of metal "carved out" at the gap makes me sad!
Actually, you are WRONG. FIRST, it is clear you don't know what AUTOGENOUS welding is. I am NOT saying I support AUTOGENOUS welding ....because I do not ....BECAUSE ...the "gaps" get filled with the parent materials .....meaning the parent materials can only become THINNER in the localized weld area/seam .....meaning the end result along the seam is weaker when only referring to the cross-sectional area. There can be a supporting argument that the material is also weaker due to change in the material properties due to the molten state.
SECOND, NONE of this welding is done in an "OXYGEN ATMOSPHERE". There is ALWAYS a cover or shielding gas used, such as argon or helium or CO2 or mixes.
It sounds like you don't know much about welding ....or you have lost focus.
Thanks for the simple explanation of oxidation and the 'space weld' phenomenon. It's interesting that a chunk of steel holds itself together, seemingly by this very principle.
Obviously, the 'cold welding' shown in this video is merely a poor translation from Chinese to English, and not the industry jargon for welding metal without heat. As far as robbing material to fill in gaps, it's quite possible to use filler rod in this process, instead of a simple autogenous bead. You can add as much filler as you want, one blast at a time, to build up whatever thickness you like. You'll want to cool off your work intermittently, though. You're not just limited to one autogenous bead with a carved out profile. Also, if you can flip the weld over and weld the back side, the penetration of the two beads is likely to meet in the middle (assuming the metal is thin enough that one bead penetrates half way). Metal that is this thin isn't likely to be supporting tons of weight, so 'strong enough for its purpose' is all that matters.
@@taxicamel Actually you seem to have lost focus before you even read his comment. Try reading it again, very very slowly. Sound it out.
As a welder who randomly came across this vid and realized, physics is not imaginary, this is fake. After checking your channel you know it so, kudos for all who did homework. My daughter paints my nails and I will still wreck a person who takes me down. Keep up the great work!
Maybe this is something for sheetmetal repairs on classic cars, because you dont get the destortion, that you would get with normal TIG
This is nothing new. Single "shot" TIGs are used in the injection mold repairs, for example.
I was thinking this too. 🤔 I wonder if it would be strong enough to not crack later on down the road. (Pun intended)
The first definition you mentioned is also called diffusion bonding & we used to do it @ Pratt in a vacuum chamber welding turbine components together. metals were very thick & clean , pressed together with many tons & sometimes had an ultrasonic vibration applied to one part.
My curiosity has been satisfied. I see these videos on tiktok but was lost in the comments finding the name. Thank you for taking the time to explain what it is. I was fascinated by how the sharp tip on the hand tool could do the weld but then be sharp again after each tack. I thought if it was being melted then it would end up bulbous like soldering wire looks.
Thanks for the video it was very informative. I was really wondering if it would work on something like a gold ring.
That moment when you welded shorter filler rods into longer ones together, I was like wow, thats effin genius man. This man will single handedly bring down big filler rod
Do it all the time.
@@michaelszczys8316 Same here with my alloy 602 CA nickel alloy rods, at $36.00 a pound I waste very little of it.
Dude ! You're freaking me out!
I thought I clicked on the Sharpie Goth Welding channel.
Thanks for the clarity and honesty. Im looking at a project that will likely involve repairing corrosion on Aluminium hull , what welding method would you recommend ?
I can see one of these being useful for making jewelry and metal art. My tig welder doesn't start the arc low enough to weld rings and wires together.
...plus some tool/die/mold repairs. Which is real application of those "toys" (like SANWA SW-V02).
This is ideal for anything small like that. Not as ideal as a laser welder, but only 1/20th the price. Plus, it does regular TIG welding, too.
I can see the usefulness of this process, especially on thin aluminum. It would be a cool function to have on every GTAW machine.
Im pretty sure i can set my pulse tig up to do this, at least i can get it down to a few amps and it can do 20khz blips. Now i gotta go try..
One of the Chinese videos I saw showed a guy doing that stuff with a busted cup-- about a quarter of it was missing. That probably makes the process a lot better.
Good video. Sometimes when I have to tack weld really thing stainless sheets together, I use high ampere and just push the button quickly. Connects the both pieces easily together. Then fully weld them "normally"
After first hearing about this process I tinkered with my TIG welder and found done great success fusion welding thin stainless using DC pulse with very short pulse. From memory I was using 120hz with 4% pulse 100/10A - you can really run along a butt, lap, or edge joint quickly for non-structural metal gluing.
Yes, people are getting so confused about the bad translation from Chinese to English ('cold welding'). Really, it's just a nice spot weld that's very useful for certain situations. Depending on the situation, it can actually be strong enough to never break, which is all the strength a weld needs.
I run kemppi welders, the rigs have a micro tack feature, works extremely well, once you get it dialed in.
Never heard it called cold welding.
Fyi, I met you briefly at fabtech last year, you were too busy to be interested.
I have a small sheet metal shop in Queensland Australia, and enjoy a lot of your videos.
Yup, me too, micro tack is perfect for one handed tackning, it also makes it not too hot either.
It's just a bad translation from Chinese to English. We can see in the video what it is... who cares what words they use.
For me this would be great tool. At least for making my RC models. Small parts, thin metal. This seems to be very easy to use.
Me too. Metal toys? Small kid bikes? And some simple diy in the house that needs to be weld.
Ring and jewelry
Yep it's made for small parts such as for rc hobbyists and jewelry👍
Injection molding, repairs - this is real application of these "toys" (as clueless folks say).
@@qwertyasdfghjkl9604 I am doing so ten years ,recently the name changes to "cold Welding"but before that it was micro-tig and the first machine is from Europe.
I enjoy the information you are more informative than most I'm learning from other people's mistakes before I put my toes in the water will say
Im glad you cleared up this cold welding thing.
My Kemppi at home has a similar setting called "Micro Tack", it works pretty good when tacking and not being able to hold wire with the other hand.
Yeah , I've got masterTig 335 AC/DC , welding some 0,8mm on 120A 30ms ,50ms continues program .. amazing job
HAH, before I looked in the comments, I was like he must have done the nails so the welding shots don't get posted somewhere for advertisements. Great idead, but at first I was a little thrown off by it.
I used to sharpie my nails black in the 6th grade because I saw a couple pictures of Ozzy Osbourne with black nails. Got a good chuckle seeing your nails.
you flashed me so many times with that welder that parts of my childhood memory are in incorrect order
I used a kemppi that haved a spot/cold weld option, I used it to weld a stainless steel guitar in like 1mm thickness sheets so I need it to be cold for minimize the heat deformation
I think the best case use for this welder would be for art, or making intricate things out of metal.
TIG welding is a good method for a lot of APPLICATIONS ...art would be good. But ...you don't need THIS one welder to TIG.

@@wiggsan This one (in the video) is Andeli TIG-250MPL.
@@hxhdfjifzirstc894 Thanks!
Good vidjoe. I might be to late for suggestions but here it is. I’ve seen a process where surface pitting on fine steel parts (firearms), were repaired using a high end laser welder. I assuming they have a vacuum box. The pitting on the part is fine. What they are doing is putting a very small cross thatch of spots and then resurfacing using files, stones etc to smooth the whole thing down. And then bluing or whatever original finish type.
Very specific application of antique pieces. Heat distortion is a big deal, and amount of filler if any is minimal. I think I will practice on a garage sale BB gun before I would attempt this on grandads Boar war rifle ?
A laser welder simply uses pre/post argon, like a TIG welder... there is no vacuum. They can use filler if they need to. The only difference is a beam of light melts the metal, instead of an arc. Of course, the laser welder is going to have optics to precisely aim the beam... with crosshairs like a rifle scope. If you crank the laser up really high, it'll blast a hole straight through a coin in one shot. Big lasers are used in the military as weapons.
First time viewing and this vid was awesome man great job definitely subscribed now that foil weld was something Iv never seen before thank you for doing what you do wow
I always thought this process is designed for cosmetic purposes and not structural. For an example, a range hood made of thin stainless still. Or anything made out of thin stainless sheet for that matter.
Hey I have a TIG welder AND I can't weld
David Guyton so sale it.
@@DavidGuyton or send it to me, i need one
Naaah once it needs to hold something together is structural.
About the only thing it’s really useful for.
Great video as always Justin! As much as i like the new "vlog" style videos with the truck, I really miss this style of video where it just seems like its you and the camera knocking out some cool and informative things!
I’d love to see you build a damaged spot on a P-20 or H-13 edge with it. Just to see if you can repair a small edge without blowing it off.
Yes. That is the purpose of those machines. Example: SANWA SW-V01 - this is the real deal, not toy.
As some one who is not a welder, thank you for the informative video.
I was seeing a lot of cold welding ads now I'm getting ads for laser welding!
Finaly, someone buy it and explaint the stuff with english
Thank you, you answered alot of questions in a short time, most people ramble on...
I would class my self as a VERY novice welder who has learnt stick welding to make some anti tip over out riggers for a pedal trike, for want of a better name. I was welding 1.6 pipe bent to shape then welded to some castors. I practiced for about 6 hours just to get the amperage, stick distance and angle right before I managed a weld that seemed acceptable. It had a few blow throughs in the process which I has to make good.
Taking advice from neighbour who’s an experienced welder he told me to avoid cold welding or joined stitch welding as he called it as it would look ok but not hold up when needing to. I avoid this frowned upon technical and loaded my welds afterwards and they held up.
My neighbour reconned not too bag for a novice which I was quite chuffed about 😊😊
Still practicing and watching videos.
Cold welding can only be achieved in a vacuum, or any area without oxidation.
Yes, this is just tack welding with TIG xd
Kinda odd that they called it a “cold welder”, considering true cold welding is a whole class of processes unto itself (explosion welding, stir welding, etc), none of which have anything to do with this TIG tack machine
Cold welding is when you only use pressure between two perfectly flat objects, without any additional heat applied
everytime I see a video about "coldwelding" I could completly loose it. Since I'm in a student-group building a satellite we're dealing (or trying not to) with actual cold welding! I hate wrongly used expressions
Forty years ago, before auto helmets and inverter welders, we used a gouging rod sharpened to a point to produce very short/quick arcs to fit-up 20 gauge stainless sheets for bench tops, face-shield down, but shade-visor open, and just blink for the flash. A manageable risk.
Then, do a few very small tacks with the TIG before the weld run.
We also had an assistant trickle water on the back of the weld during weld run to keep the heat under control.
Sheesh, we don't do any of that now with current technology.
Try that sometime; sharpen a gouging rod to a pencil point for very small short arcs. But have a very clean shade glass or adjust your auto helmets to suit.
Or just blink.
I was wondering if anyone ever used water cooling for this kind of thing. Thanks for the info.
You Vado the same with high frequency tig and set it to tack weld. I’ve done this 20 years ago. I’m always a fan of welding stainless steel sch 80 pipe full peno
Could be a good feature for quick tacks or for things that don’t need to be strong and are more for looks and decoration
Thanks for clearing that up. It's been keeping me up nights. Well, not really. But I did kinda wonder what it is a couple of times.
As a woodworker, who could benefit from occasional welds but always finds a work-around to avoid welding, the thing that appeals to me about Cold Welding is how simple it appears to be. I attended welding school and certified almost 20 years ago, but ended up going another direction. The thing that prevents me from my welding when I'd like to weld, is the complexity of all the necessary equipment, setup, and the knowledge that goes along with it (I've forgotten most of what I've learned). For example, if I want to weld two pieces of scrap together, I don't want to have to figure out what type of metal I'm working with, order the specific weld rods, etc. This seems to cut out the entire step of selecting rods, and creates a neat (if weaker) joint. Also, it appears that you can join dissimilar metals rather easily.
If you're gonna weld wood I'll gladly watch the video😂😂 . Seriously, this process is nothing more than short pulse tack welding. I've seen similar function on reputable brands such as Kempi etc for a number of years before this 'cold weld' bullshit.
Mig welding the the answer you are looking for then!
Its a fair amount easier to Mig weld than Tig or Gas weld. You could be good enough for hobby type stuff in Mig by watching some CZcams videos.
Don’t have to worry about selecting rods, just take two pieces of steel and go do it. You can find pretty inexpensive Mig welders at Harbor Freight and places like that.
This ‘cold welding’ is basically useless. If you tired to do this the piece would be about as fragile as if it was stuck together with Elmer’s glue. You could really only use it to weld things you wouldn’t be touching or moving. Like a model of some kind that is never coming off of a display stand.
Actually Cold weld also occurs on the space, where materials tends to fusion in the cold since there is nothing separing them (No air no dust). Actually its a huge problem to the space agencies since they have to use certain materials to prevent this.
Happens with super smooth lapped precision gauge blocks. If you put them aside while having them stuck together with the friction alone, you end up with never being able to separate them, due to optical contact bonding effects.
So its just a fancy name for spot welding...I'm still new to tig welding but I've learned alot watching you and others and lot of practice
I can see where it would be handy for sheet/body work. Low heat joint means less warpage during tacking/welding.
thats what i was thinking seeing as i just did a load of rust repair xD
Amen
What a great vid. I legit have been seeing those "cold weld" videos and was confused. Makes you almost question what you know.. Lol
Also for half the video I legit was confused with the painted fingernails and the watermark. Great job haha
So you're not confused with the finger nails, well I still am whats the deal ? Watermark ? I'm lost.
@@haroldleon7249 there are a bunch of Chinese "Cold weld" like tiktok style videos on the net. And they have the weird watermark and sometimes its a person with painted fingernails.
It’s for jewelers…. Im a jeweler and I’ve been doing tons of research to get around something the jewelry industry is really good at; dressing a piece of industrial equipment and selling it to artisans for $4000. Working my way from the machines that are marketed to me back to the industrial units I see in the hundreds and back again, I finally understand what’s going on. Just as pulse circuits are nothing more then a controller supplementing the user of a welder that would either be on or off at any particular setting; the controller of a pulse unit regulates the input of this tremendous energy into bites that more delicate materials can handle. I’m not surprised that applied to material functions that you are accustomed to handling, that these welds would be impractical, but for someone trying to put earring wire onto a thin bezel holding a potentially delicate stone, it is a time saver.
I’m honestly surprised this isn’t being marketed to jewelers because it’s practically 1/4th the price of a similar powered unit in the jewelry world. As it happens from there the price starts to get ridiculous with add ons that only jewelers would need (like a microscope and fancy LCD interface). But for us working in fine metals who are aware they are being sold a pig with lipstick, and would rather have the pig without to save some scratch, this is what I’ve been hunting for.
I’ve seen even further into my frugal tendencies and would consider a pulse control unit so that I could practically use most welders home depo has with a similar level of precision you get from a Lampert PUk 5.1 that starts at $3500. You’ll likely roll your eyes to know that researching this I had to come to understand electrical principles to a degree that I could get around the constant tactic these companies use to discourage cross industry use of the same product. They will, if they offer it upfront at all, an advertised power rating in Watt/seconds or Joules, cleanly discouraging people from finding out a unit you used here will do most any job they require without the price tag. And $3500 for the Lampert is without microscope which begins at around $5000. Btw that’s still mid market for expensive. Check out laser welders….
I did a DIY version from an old LCD mask and switch with my 160 amps DC TIG : as soon as the arc is established open the switch. after seeing the PUK Lambert. Welded some broken titanium glasses frame, broke them again same place. The weld did not completely penetrate (surprise for cold weld !) so not that good a process for that or was it me, welding titanium with just a box with a plexiglass sheet as partial coverage... ? PUK goes to 400 amps though.
Hey gang, my lincoln ranger when hooked up as a tig welder with power at zero can scratch start and weld the sharp end of razor blades. Believe it or not it has a rather stable low amp dc arc.
Pretty cool to see the foil weld together. I thought it would be too thin. 👌 💯
i could see where it might be used for small scale modeling or adapt it to 3d printing unit with a wire feeder.
With a hellavalot of fans to keep the part from melting while printing it, so you don’t have to wait 14 years for it to cool down in between adding filler material
Love it! Felt like i was at a rave with all thr strobe flash and stuff lol
Thank you. You seve me some money, I was about to buy it, but first I diced to investigate a little bit more.
This type of welding has been used here in europe at least for quite some time (at least over a decade, so certainly not new).
Just not in construction welding, but other, more technical applications.
There are also specialized versions with moving tungsten electrodes.
Where do you think the chinese copied it from?😅
You need to have the SloMo Guys come in with their equipment and get some footage for further analysis.
I didn't pay attention but looked up at 0:35 and winced at him wiping off the blade. Real eye opener
So useful for very very small things but not really anything larger kinda what I thought when I kept seeing these on it shorts and having been a welder for awhile now.
Cold welding or "micro-tacking" has its use for, you guessed it - tacking pieces together. quick and simple.
I would not use it for anything structural, however, if used on thin materials (< 1mm), like for bodywork, you can negate any warping that may occur.
thats what I was going to say, it will do great on bodywork
Thanks for the test, had to talk a friend out of buying one
Ahhh the old "I have a friend who...." travesty 😆
@@Mr215Alive Right, the one that buys the cheaper welders and says they work exactly the same as the brand name machines.
maybe its decent on the "regular" tig mode. remember the "cheap" welder he tested a while ago?
@@g-low6365 very true. Forgot about that.
@@braidenstevenson1665 They don't sell cheap brand new machines?
I was flux welding with my zipper down, squatting. Caught some spatter in there. I will never forget to zip my pants up again.
Haa, don't feel bad, I got some splatter in my helmet and set my hair on fire 😅
Im glad you made this video. I understand what's going on with the process, but I also understand if you fuse the base metals without fillermetal (particularly with the "jogging" or pulsing on and off) the weld will almost always fail due to thin weld zone areas, inclusions in weld and poor fusion.
With this method sure, welding without filler with tig is good enough to meet standards for balcony Railings or some other stuff that people can lean on. Iirc its 1kN per meter or something.
@@readordienn that would depend on what metal the handrails are fabricated from. I would not recommend welding ANY handrail without the proper filler rod AND joint preparation. Stainless is probably the only material, but if there's any gap on the fit up when welding said handrails, you are going to need filler wire.
@@yourdrummer2034 ah forgot to write. Ss304 no gaps, holes filled if they appeard
@@readordienn sounds legit.
