Good job and well done, but there is a mistake. I put a weld over another weld, and this is a mistake. You have a nice touch in welding💙💙🇩🇿
Good day, whats the name or brand model for your tig torch??
You can use laser welding for more efficiency
Finally, awesome video with tons of info of how to do things in welding! Keep it up!!! 👍🏻
Great welding as always man! Your an excellent welder and fitter. You skills are definitely improving. I'm glad you tried the bigger cup size and tried to limit stopping on your cap. They are really looking better!
Another amazing video well done mate great advice and tips like normal and excellent shots. the tig welds look real smart a master at mig and tig 👍👍👍
You finally got a centering head to locate all your couplings good job
Tig, Mag and PIPES. Man u r Expert with things you do, hope to become 1 some day . Keep it on ,great work !
Thanks dude
Just a tip, my friend who welds aircraft exhaust systems says using a graphite pencil will cause them to crack on the line. He uses a Silverwriter pencil, a colored pencil with silver lead. I think a fine felt tip marker like Pentel brand would also work? He has been at it for 40 years now...hope this helps on any high heat applications like jet exhaust systems.....Carry On....PB
Been looking for a video like this for a while thanks
Great work! Merry Christmas from Edmonton, Alberta👍
Tons of usfull tips and tricks respect
Thank you so much for sharing!
Respect from Missouri
NICE ..walking of the torch cup !
Great job's you are doing. Greetings from Holland
I love the amount of yazoo bottles you have on your table 😂😂👌🏻
seen a couple of your videos, impressive skills
would have liked to see you weld stainless with mig or stick, This is what we also do regulary, great job man ! I usually check measurements and angles also when finished welding.
what i also like is that you keep argon-sheelding when you terminate your welds. Since i also do maintainence welding - guess where a seem will leak if it has not been sheelded properly. Nicelly done, good seems with proper roots.
respect from poland :)
Great work man! Im just wondering if there was a chamfer on your pipe before you welded them?
Great viewing
Excellent video ✅💯👍
Stepdrills works perfect on ss tubings
Do you run a taper through the pipe connector so that you can compensate for shrinkage, or does it only shrink in the bottom where the weld is? Do you experience that the plug on stainless steel can get stuck in the threads after it's welded and cools down?
I worked at a nickel refinery as a mechanic, and would often do simple welding-jobs, most of the time arc or tig-welding stainless steel, I even tried titanium a few times. I remember when I welded pipe connectors I would usually have to run a taper through after the welding job, if I would run it through a plate/flange and weld on both sides. I've had a lot of instances where stainless steel bolts/nuts cold weld, so I got concerned when I watched you weld.
Hey bud I'm a little behind the comments. But it is possible to make both amazing, in saying that your internal weld is key.
Nice root and penetration! You got some skills.
Very good job 👌💪💪💪
show de bola meus parabéns.... Brasil 👍👍👍👍
Brilliant vid💪Do you do any mild steel ?? Job I am in now is very similar stuff 👍 your vids are going to be really helpful 🤟
root and cap are great...just need a better Torch....intresting how it causes a strobe effect eh....maybe a non led lamp? can't get enough of your intro music, would love to know who the group is....Cheers from USA, Paul
You can't weld nipple directly on previously made weld. The heat affected zone is +-25mm from each weld root. So, there shall be minimum 50mm distance between nipple wall and pipe circ. weld.
A lot of places honestly don’t give a shit. Steel mills, paper plants are some examples. Refineries, nukes, and more serious places where there is QC they care.
In my opinion it would be much easier to walk the cup uphill then rotating it 💪
Why didn't you use walking the cup style on last the T-fit joint weld?
Good work bro it’s choice bro
nice welds
Both are just as important! They are your signiture of who you are, and how you fit your fab. work! Anytime you have an oval shape fitting to fit to your most round fitting add more tacks and pull the oval out.
Nice !!!
So. You said purge with nitrogen? Is it argon or nitrogen? I have never purge with nitrogen, does it really work purging with nitrogen? Thanks
how much purge did you do?
What wall thickness was this pipe mate?
How do you use such a steep angle without losing shielding, every one has always told me to keep the torch vertical to stop air from being drawn into the argon stream from the lens.
Use a gas lense, and the appropriate gas flow for the size ceramic you're using and its absolutely fine👌👍
I am guessing you have a switch on the torch? 🤔
I've got hundreds of these to do in 24 inch gonna be a long month
awesome job bro keep up the good works
You purge with nitrogen?
I would have used a Starrett hole cutter instead of a Plasma torch to cut the coupling hole.
Super👍
Better root if you ask me, with pipes like this its about what is going through the pipe
how long do this?
where did u find those rubber sillers or where did u got that rubber from ? I need those for a job like yours
Your local welding supply store might sell them, and if they don't, they should be able to forward you to a supplier.
Your tig torch, what do you use to control it. Foot pedal or lift arc? Can’t tell? 🤔
Naa just a button on and off
Want to be careful walking the dog on fillet like when welding the small socket fittings. Very easy to get a concave fillet like you did. Try it freehand, dipping nice and fast to get a nice sized puddle going, and a decent build up giving a decent sized throat
Ill give that a try thanks
Should I go on indeed & search for pipe fabrication jobs? I live in the usa
If you're a welder then pipe welding is where u want to be
Not sure if you did. But after your root. Let the pipe cool right down before doing hot pass or cap. Leave the gas running, helps it cool. Then your cap will come out a lot cleaner. Also keep your filler in the gas shielding, looked as if you where pulling it out a bit far. Nice root. As long as it's sweet on the inside. All is good
this is a single pass job, as far as i can see he didn't do any cap pass
@@raulduke85 you're probably right. I only gave it a quick watch. Doesn't really matter his root is good. All that really matters
@@liamjenkins82 well yes but the discoloration outside is a bit too much imo; it's good for most applications, but if u love welding you aim to the top tbh
@@raulduke85 yeah I agree completely. Pretty sure he was bringing in impurities with every dab. Filler taken outside of the argon zone. Didn't clean the weld area before hand. We all strive to do better that's for sure
Are you welding machines powered with three phase or single phase at your shop?
Running the Fronius pulse mig sets, thats gotta 3 phase
Be very suprised if not
If your root pass is no good the entire piece fails... Sweet root pass, you may proceed 😎
What brand and model welding torch are you using ?
I think its a esab air cooled, wp26
Do you ever use purging paste
Want to steer clear of paste if you can, unless there is literally no other option. Its horrible messy stuff, gives off some rotten fumes too, and all needs cleaning out when finished. Its simply a mega PITA
How Thin those pipes?
Bon Boulo😆😆👍👍
Le agradezco su fuera en castellano peru
Waoh......
Seems like after each dip u r retracting the rod too much and outside the gas shield, causing rod to get oxidation. Next dip introduces oxides into the weld pool.
you would see the oxides in the cap if that was so.. there clearly isnt! seems like your just pulling shit out of your ass
Stainless is your friend, mofoka cleans itself
what kind of weld is that?
Tig on stainless steel
👍👍
Nice video but why do you not use the puls function on the tig welder instead ? Then you don’t use any wire…
That machine doesn't have pulse and they dont want a flat weld so i need filler wire to build it ip
Depends on the procedure he's working to aswell.
Be very hard pushed to find a procedure for welding pipework with pulse tig.
Have been doing the job almost 20years now and haven't seen one procedure with pulse, other than pulse mig😕
NO its easy to make a procedure for tig also. You call Force and tell them that you want to make your own procedure and the you can make the procedure as you want….
You are working in what country?
In the uk
Next time roll your pipe to get better position on your weld that more comfortable and your cup walking wouldn't be as sqeaky! lol!

This may be a weird question, but does the shop you work at ever give you grief for filming videos during work??
Hello！We are the manufacturer of laser welding/cutting/cleaning/marking machine, did you need these kinds of equipments in production ?
Stain Clean? 💁🏽♂️
I just want you to know first, is that I'm not trying to badger you in any way. I'm only trying to give you some experience I have to share from my father and brothers before me! I see your tacks in four places now split between them to have an even eight tacks.
👍🏻👍🏻👍🏻🤝🤝🤝

That's the worst ground cable I've ever seen.
Relax your wrist more on that torch position! your heat shows me that you're trying to catch up with your root all in one pass! Burning too hot for the gas you're using, your tungsten is carrying the heat spread too far from the point objective!
Please sharpen your tungsten more to a very sharp point! You need to know one important thing? That is to measure your gas cup inside diameter and divide by 2 that's your stick out from gas cup end.With that heat you need 3.2 filer rod, and your gas to purge burns hotter than your argon gas! That being said your welds on your cover show you're too hot! Using that combo of gases you must let that cool down after every pass! Try running with about 68 to 73 amps.
We use 1.6mm rods for root pass, a 3-4mm gap (on 6" pipe and above) and root at around 85-90 amps. (AWS and EN1090 class4 approved procedure, along with Nuclear approved procedures.) Most often use a size 6 ceramic with about 8mm or so of stickout. 2.4mm grey tip ceriated tungsten. Sharpened with a taper about 6mm long then the very tip flattened off. Then up to a size 8 ceramic with about 10mm stickout, 2.4mm filler and 150-160amps for hotpass. Fill passes between 150 and 180 and usually i go back down to 150 to cap off. When welding 8" and above especially sched40 and heavier, fill passes are at 200amps still with a 2.4mm filler.
So are we going about it wrong then? Before you answer btw, every single stainless job we do is subjected to a minimum of 10% radiography or DPI for slip on flanges and olets or other fillets, with around half of the jobs being 100%. Also quite often although not always, welds are also PMI checked especially on the nuclear side, to check the material composition of the finished weld. Personally have only had 2 repairs on stainless in the last year, one in the workshop and one out on site at a chemical plant.
Also
Talking about purging gases, Nitrogen doesnt "burn" and is the preferred gas for purging super duplex grades such as xeron 100.
