7075 is stronger in UTS terms than mild steels while still being way less dense, so it has its uses, just not as a weldable material. Unless many bike manufacturers lie about their materials (Which wouldn't surprise me at all to be honest, the industry seems to mostly be populated with designers and snake oil salesmen who think they're engineers) 7005 is weldable.
@@peglor OR do they use industrial welding options? There are larger/higher power requirements you can get in a commercial setting, that you cannot get in a home.
@@TechyBen The problem is that welding them with anything that relies on melting (like TIG) significantly weakens the aluminum, regardless of weld power. Friction Stir or another solid-state welding process could be used, but it's usually easier to machine these small bits out of a solid block.

Lol I had a feeling it was going end up being some 7000 series alloy. I think a lot of the 7000 series alloys are used in machining operations because they tend to have exceptionally high hardness, harder than mild steel a lot of times. Most of them aren’t weldable by any conventional fusion arc welding methods though. This is the first time I’ve seen someone actually attempt it though. That was a pretty catastrophic reaction to welding lmao!
Thanks for another excellent video, Tony! I wonder what alloy that motorcycle part was that you welded a while ago - it was also an 'unweldable' alloy, as I recall.
I think the difference between this material and the motorbike footpeg is this is a non-weldable alloy, and the footpeg is a non-weldable grade. The difference being that the grade is in fact possible to weld, though you lose some of the desirable characteristics of the grade (toughness, strength) but a non-weldable alloy means the composition of the metal rejects the metal supplied by the aluminum welding rod.
@@magicoddeffect Correct - CZcams recommended the video, so I went back and watched it. Now I'm wondering how the footpegs are holding up. Might be a good follow up chat video. czcams.com/video/AhMil-ibUTY/video.html
@@Ddabig40mac In the metallurgical world, 'grade' and 'alloy' are synonymous. What you describe is condition - hot-rolled, cold-worked, quenched and tempered, solution treated and aged, etc. Grade refers to an alloy specification, which usually includes a prescribed chemical composition. Welds are always susceptible to cracking due to a variety of factors like formation of brittle phases, grain boundary segregation, solidification shrinkage, and degradation of mechanical properties in the heat-affected zone. Certain grades of aluminium, including most 2000 and 7000 series alloys, are especially susceptible to liquation cracking as they exhibit a large solidification range (difference between liquidus and solidus temperatures) due to their chemical composition. This can be avoided to some extent by judicious choice of filler metal, but some alloys just cannot be fusion welded no matter what filler metal you use.

@@horrorhotel1999 Yes, you can use the HTS2000 type brazing rods for most of the 7000 series alloys, especially given that the brazing rod has a lot of zinc and that's a major alloying component of those metals, so they bond well.

Your comment about the mad scientist got me curious, so I did a little googling. Turns out, Prof. Xiaochun Li and his team at UCLA managed to develop what's basically a filler rod for 7075 that's infused with titanium carbide nanoparticles, which somehow fix the uneven flow issues of 7075. Tensile strength of the welds were up to 392 megapascals. Not exactly accessible for a home gamer, but apparently they're working with a bike manufacturer on implementing it into production. Sounds like one day, maybe in the not too distant future, we'll be able to weld 7075.
Well, yes and no. There's two distinct problems with welding 7000-series. The first is that the chemistry of the material is such that conventional methods and materials don't actually weld it. That could be fixable by specific filler rods with specialist chemistry. The second is that this is ZINC alloyed aluminum we're talking about. Welding processes are generally hot enough to boil zinc off/out of the material being welded, creating an extremely dangerous fume. That's where that white residue Tony found below the failed bead comes from. On a manufacturing line, you're probably using robotic welders, so you aren't worried about exposing workers to the zinc fumes. For the home welder...just don't. It's possible to protect yourself very effectively, but to do it really well you'd need to combine a welding mask and a respirator with the correct kind of filter for protecting against both fume and dust forms of zinc. You'd also have the possibility of fine zinc dust loose in the shop, which is not a happy thought.
Most of TOT’s videos are beyond my capabilities and a lot just sails over my head. That being said I watch them because he is so freaking hilarious. It's a tool oriented stand up comedy jam everytime. Thanks This Old Tony
Thank you ToT, good advise. I still have lung issue after 30 years of brazing a leaky galvanized soak tank that was originaly sealed with lead soldering. The detergent chewed it's way through over many years. I thought it would be a good idea to braze it with the yellow flux bronze rod. I wish I knew better or that someone took the torch out of my hands.
Thankyou Tony, for at least attempting to weld 7000 series alloy, because we use some at work and I told the Engineers that the handbook says "that stuff is unweldable", and now you have proven it. I have heard that "some" are weldable under special methods, BUT most are NOT, we have 7075 at work, and the book says ...NO.
I LOVE how much you’re posting now! You don’t know how many times a week I check for new this old tony videos, and hey your videos are the only way I can fall asleep nowadays, it’s soothing
OMT!!!! The ToT has granted us meer mortals another video!!!! Just like winning a quadrupedal jackpot in Vegas! Just wish it was longer... But, Thanks Tony.
Wow! Fantastic! Two TOT videos in just a couple of days! This one was so good, it almost makes up for the forty eight minutes and one second of my life that I will never get back. 😜
I'm a hobbyist, just starting and getting by with the scraps I can find here and there. Nothing that matters yet, just goofing around and learning as I go. I'd been doing all right with aluminum; not great, but making progress... and then I hit a spell in my scrap pile where I just could not get a good puddle to form, could not get good bonds going, and got pretty much the exact results you did. This explains so much! Thanks for the informative and funny videos! (Right?)
Here so early. Old Tony is so old. We are watching in 480p! Even I had to hit the side of my Tube TV to stop being so fuzzy. Also, moved the rabbit ears.
Strange, this is the first video of yours sent to me in ages. I’m a subscriber and personally find your videos my favorite. I’m not sure why CZcams doesn’t want me watching.
Really nice to see Tony's hands with a tig torch in them again. Seems to have been a lot of Maho stuff recently. All interesting, but there's something therapeutic about watching a nice bead being laid down.
Tony, it's the same as if you take a sheet of aluminum and try to form that sheet, it will crack when you try to have it conform to a specific form. But if you cook/temper in an oven that same sheet of aluminum, after you won't have any problem to make that aluminum to conform to the curve shape and you would see any cracks. NOw in your case, that alloy you tried to weld. What happens when you try to weld cast iron cold, it will crack after next to the weld. Now that alloy did the same, the weld bead lifted when it began to turn cold. A friend of mine had this same problem to fix a machined bracket that cracked and broke off that was made of a similar alloy, it looked like aluminum but was impossible to weld. Here what we did to weld these two pieces. We made a jig to hold these two pieces for welding. Now we heated in an oven both pieces for about 20 minutes so these be very hot. ONce we pulled them out we placed them in the jig and started to tig weld them and the weld did stick and held. And is still holding today. Now if by any chance your pipe is made of the same alloy, maybe you should try heating that part in an oven and take it out of the oven and put a bead on it. And see if the bead stay welded to the part. PS. Don't forget to remove any oxydation after the part comes out of the oven if at the first attemp it did not work. And if it doesn't work, well you have something different for an alloy.
Wise old people taught me that radioactivity is a general concern whenever material is scavenged, simply because you never know the life-story of salvage or scrap.
This is why you only use cruelty-free, organic, grass-fed, stock without added preservatives.

Well, yes and no. There's two distinct problems with welding 7000-series. The first is that the chemistry of the material is such that conventional methods and materials don't actually weld it. That could be fixable by specific filler rods with specialist chemistry. The second is that this is ZINC alloyed aluminum we're talking about. Welding processes are generally hot enough to boil zinc off/out of the material being welded, creating an extremely dangerous fume. That's where that white residue Tony found below the failed bead comes from. On a manufacturing line, you're probably using robotic welders, so you aren't worried about exposing workers to the zinc fumes. For the home welder...just don't. It's possible to protect yourself very effectively, but to do it really well you'd need to combine a welding mask and a respirator with the correct kind of filter for protecting against both fume and dust forms of zinc. You'd also have the possibility of fine zinc dust loose in the shop, which is not a happy thought.
@@evensgrey See, you can tell I've never actually welded.
Thanks for being YOU TOT. You have taught me so much more than I didn't know that I didn't know.
Most of TOT’s videos are beyond my capabilities and a lot just sails over my head. That being said I watch them because he is so freaking hilarious. It's a tool oriented stand up comedy jam everytime. Thanks This Old Tony
This man is a global treasure. Protect him with high speed steel
Thank you ToT, good advise. I still have lung issue after 30 years of brazing a leaky galvanized soak tank that was originaly sealed with lead soldering. The detergent chewed it's way through over many years. I thought it would be a good idea to braze it with the yellow flux bronze rod. I wish I knew better or that someone took the torch out of my hands.
😲☹️
Thankyou Tony, for at least attempting to weld 7000 series alloy, because we use some at work and I told the Engineers that the handbook says "that stuff is unweldable", and now you have proven it. I have heard that "some" are weldable under special methods, BUT most are NOT, we have 7075 at work, and the book says ...NO.
Transparent aluminum with some “parent” mixed in.
“I’m This Old Tony.... Play Safe...” Quantum entanglement of CZcams favourites 😍😍😍
Needing some Extremely Danger stickers myself...
I LOVE how much you’re posting now! You don’t know how many times a week I check for new this old tony videos, and hey your videos are the only way I can fall asleep nowadays, it’s soothing
OMT!!!! The ToT has granted us meer mortals another video!!!! Just like winning a quadrupedal jackpot in Vegas! Just wish it was longer... But, Thanks Tony.
"6061.....run of the mill. Get it?" If I did, I'm sure I can take shots for it. Get it? ;)
What were those sparks at 4:51 when you touched the loose weld?
magnesium?
Metal goblins with their hair on fire, they always leave the scene of the crime real fast.
Watching it at 0.25x speed makes for some good entertainment.
Wow! Fantastic! Two TOT videos in just a couple of days! This one was so good, it almost makes up for the forty eight minutes and one second of my life that I will never get back. 😜
That chicken at 1:40 is well placed, almost overlooked it.Chapeau!
Two This Old Tony vids within the past several days?? I'm buying some lottery tickets!
A walk in the cake :) I am definitely going to use that. Thanks Tony!
Best used in a sentence like: 'Rocket surgery is no walk in the cake.'
It's good, but it leaves you with a piece of park to clutter up the scrap bin.
The chuckle density of this video is great
Great vid as always Tony. Thankyou. Your content and presentation is brilliant!!!
Am I dreaming? The second video in a week!
I need a shirt that says "Extremely Danger" and a few stickers, maybe even a ball gag.
This Old Store
@@PoodlePuncher Shirt with Extremely Danger is not in the store
@@simongroot7147 I was agreeing with you, and that the should be called "This Old Store"... is there already a store someplace?
Combine that with a "Situation Norminal" (spacex) and a "Keep your Stick on the Ice" (or its modern equivalent) and you'd have a real mashup.
I'm a hobbyist, just starting and getting by with the scraps I can find here and there. Nothing that matters yet, just goofing around and learning as I go. I'd been doing all right with aluminum; not great, but making progress... and then I hit a spell in my scrap pile where I just could not get a good puddle to form, could not get good bonds going, and got pretty much the exact results you did. This explains so much! Thanks for the informative and funny videos! (Right?)
Thanks Tony very important advice in the video.
"play safe" sounded like a tribute to Scott Manley - fly safe!
Exactly.:-) I was looking for a bald dome. :-D
@@mortisCZ wouldn't mind to see TOT machining a satelite.
Wouldn't be that surprised either.
Here so early. Old Tony is so old. We are watching in 480p! Even I had to hit the side of my Tube TV to stop being so fuzzy. Also, moved the rabbit ears.
You'll need to shake your fist at the kids on your lawn for best reception quality.
Love your videos, always a joy to watch and learn.
Tony, you found that piece of unobtainium I lost years ago. Good on ya.
"A walk in the cake." Good one!!!!!! If you walk in the cake, do it with your mouth open.
It tastes batter that way!
Especially if you plan on putting your foot in mouth.
@@blahblahblahblah2933 Oops , lol.
For some reason I expected different outcome. I wanted to see it welded, despite being “unweldable”.
Thanks for the public service announcement and sharing.
Those spikes in your retention analytics are where I rewind when my wife is interrupting me watching this video. Must be half a dozen spikes or so.
Whoa whoa, 2 videos in a week? You feeling alright Tony?
He was...until the zinc bong hit he just took from that 7000 aluminum lol funny as hell video.
Must be another lockdown.
Tony, it's been so long. Good to see you again!
Another much needed PSA by This Old Tony from... erm... This Old Tony
Thanks for the vid mate. All the best from Australia
Pah. All metals are unweldable to me!
(Goes to cry)
you are not alone! :-) can i cry with you? haha
Thanks Tony I was holding that pee for 5 minutes
why would you hold that?
i hope you washed the pee off your hands.
A second video in the same week?!??!?! My sunday evening just got better. Tmrw morning i'll start my work week w a big smile:)
Strange, this is the first video of yours sent to me in ages. I’m a subscriber and personally find your videos my favorite. I’m not sure why CZcams doesn’t want me watching.
Did anyone else say "right" after the sentence when Tony didn't say it haha
I was waiting for it to be magnesium and catch fire while welding.
Thanks for the video, Tony!
Really nice to see Tony's hands with a tig torch in them again. Seems to have been a lot of Maho stuff recently. All interesting, but there's something therapeutic about watching a nice bead being laid down.
‘Minding my own business’........ hahahahaha. Thanks for sharing with us
Could you please do a shop tour? And don't clean it up we want to see the interesting things ;)
I am pretty sure what we see is the whole shop. Bench, lathe, mill, welder, and a bit of floor, all suspender in the outer space.
The huge swarf pile behind the lathe bed sated me! I felt extreme tranquility and peace after that “money shot”!
Tony, it's the same as if you take a sheet of aluminum and try to form that sheet, it will crack when you try to have it conform to a specific form. But if you cook/temper in an oven that same sheet of aluminum, after you won't have any problem to make that aluminum to conform to the curve shape and you would see any cracks. NOw in your case, that alloy you tried to weld. What happens when you try to weld cast iron cold, it will crack after next to the weld. Now that alloy did the same, the weld bead lifted when it began to turn cold.
A friend of mine had this same problem to fix a machined bracket that cracked and broke off that was made of a similar alloy, it looked like aluminum but was impossible to weld.
Here what we did to weld these two pieces. We made a jig to hold these two pieces for welding. Now we heated in an oven both pieces for about 20 minutes so these be very hot. ONce we pulled them out we placed them in the jig and started to tig weld them and the weld did stick and held. And is still holding today. Now if by any chance your pipe is made of the same alloy, maybe you should try heating that part in an oven and take it out of the oven and put a bead on it. And see if the bead stay welded to the part. PS. Don't forget to remove any oxydation after the part comes out of the oven if at the first attemp it did not work. And if it doesn't work, well you have something different for an alloy.
I usually like your puns but that "run of the mill" joke about ripped my retinas my eyes rolled back so hard.
"Play safe" outro, has someone been watching Scott Manley?
Yeah. Might as well use "Keep your safe in a vice" ;-)
"Fly"
Thought the same, I think its a reference
Right?
Scott isn't the one who says right all the time, right?

Nice. Wife said I was allowed to watch one video before bedtime and a TOT-Video pops up. So the only right choice was to watch this video.
Right?
caution
don't watch with wife
she might run off and try to find him
he's a Womanizer this old Tony
i think you need a new wife... she's too controlling like an angry grandma.
It's only Monday morning and I already learned something. Thanks!
Actually set me back a step when you suggested "Beryllium" because yah you totally want beryllicosis yah no.
Yeah, that always scares me because I mostly use salvaged materials.
bring your Geiger counter
@@bielanski2493 not radioactive afaik
Wise old people taught me that radioactivity is a general concern whenever material is scavenged, simply because you never know the life-story of salvage or scrap.
People need to try it more.
Speaking of unweldable, what happened with the bike repair on the "unweldable" alloy?
scratched knees.
And some choice words
You never cease to make me laugh, no matter what the subject is.
love the raised hand animation. More videos need that.
Teach 🤚 Hey Teach 🖖 You didn't explain how bikes out of 7k Aluminium stock are welded @ToT
I don't know of any bikes made out of 7k series aluminum. They're almost always 6061.
@@jameswright4732 Banshee Bikes for example, they use 7005. Welding an alloy like 7075 seems to be a bit more involved though.
Pieter van Gisbergen there was a European group working on it with a space laser, but it kind of got out of hand.
