Welding Steel to Aluminum (And Other Inappropriate Welding)

- Attempting to weld steel to aluminum, as well as trying to weld aluminum with an improper setup using a Miller Multimatic 215 in MIG mode with C25 shielding gas only. Surprised at the results of aluminum welding with C25!

@MillerWelders really love my 215, it was a champ through all of this! Also the ArcStation 30FX, Digital Infinity Hood, MIG Gloves, and Indura Jacket...all top notch!

Props for just experimenting 😎
Thanks! It's a fun way to learn.
I work at a tank trailer company, and whenever we had a big gap in something we would put a bar of aluminum on a steel tank or vice versa, and after the gap was filled the bar would break off, always. It was the only way to fill big gaps. even spray arc aluminum would break off the steel bar, and you could use the same bar over and over. Just had to buff it off once in a while.
Yup, handy to have dissimilar metals for backers!
Welder here, 15+ years in the trade. To my knowledge, there's only one way to fuse two different types of metal, and that's explosion welding. If you don't know what that is, look it up. It's wicked.
Years ago I heard about a rod type designed for dissimilar metals, but I've never used it so I can't say.
There's also soldering and brazing, but since it isn't fusion, I don't really consider it to be proper welding.
Yeah, I've heard of the explosion welding stuff, very cool!
I guess there are some ways to join them, but I just wanted to see what happens first hand. The aluminum with C25 gas was more surprising though, goes to show just how much difference the shielding gas can make.
cladding is one technique. they use it in certain refinery vessels to put a thin lining on a much thicker stainless steel tube or tank. Ultrasonic metal welding will also allow dissimilar metal fusion but in very small parts.
You have impressive technique. No shame in trying and seeing for yourself. Great video!
Sometimes you just have to try things out for yourself to learn :) Thanks!
Question: If flying weld spatter (produced while welding steel to steel) fell about 2 feet down onto a flat sheet of aluminum, would the individual unwanted beads of steel (when cooled) brush away (off of the aluminum sheet) fairly easily? Could you run an experiment to show this?
They do just brush away...but I'll throw that on the list for when I do a revisit to this video. It's in the plans, I have 100% argon now and DC TIG capabilities that I want to try some more things.
They would brush away, but it would leave a burn mark on the aluminum
Did you get the Miller Underpants aswell???
THEY MAKE UNDERPANTS!?!?!? lmao
I’ve done it before for a radiator frame for one of my hobby cars. It can be done.
It's literally not possible without explosive welding...either your welds have already fallen apart like these did, or the materials weren't what you thought.
Also I wonder if you could weld them together with thermite welding, using iron oxide and aluminum to start a reaction and then have it in a mold so it melts them both together
The only way that I know of is explosive fusion.
@@SomeGuysGarage that's the only primitive way now, but it certaiinly isn't impossible in terms of what is actually possible. At the end of the day, all metallic and chemical bonds are electrical, so it is just a matter of creating the correct atomic structure where they are connecting, but with today's technology we are left with these primitive bulk brute force methods. With your scientific mind, I'm betting a book on a new atomic theory would interest you, it blew my mind, the Nature of The Atom by Edwin Kahl .. spoiler alert, it blows away all 37 existing mainstream atomic theories.
Actually if you look up Fronius CMT, they have a procedure for welding aluminium and steel.
It's a robotic system.
Did a quick google...sounds like it's more of a braze then a full on weld, but still a neat process! Thanks for sharing :)
@@SomeGuysGarageyea that sounds right now that you mention it.
P.s it would help to have a teflon liner for your mig gun if you plan on welding aluminium.
Also use 5356 wire instead of 4043 it's stiffer and will feed better.
@@deepwinter77 I had some luck feeding the 4043 with the standard gun/liner, I actually did a little aluminum welding with it a few weeks ago (have since got straight argon) to make a couple gauge rakes for leveling the floor in my basement...went ok :)
If I ever do more though, I'll look into those things, thanks for the tips, appreciate it!
You can definitely use dc tig for aluminum, some places use it for thick aluminum. Look it up
Interesting....with just straight argon still? And does it make for a dirty weld? I was always under the impression that it was the "cleaning" effect of AC that was desired?
@@SomeGuysGarageAlly has to be Pure argon if you’re going to mig it 👍
Good video! However, where Is the "flux core" experiment 🤔?
I plan on doing a follow up to this video soon, I have a tank of pure argon now and really want to re-try aluminium. I have a spool of flux core kicking around, so I'll add that to the list :)
everyone says that.. as you said.. however they make rods specifically to do this and tons of people weld aluminum to steel for decades lmao
Braze yes, weld no.
Thank you!
I love the scientific method and in general, I gain a much better comprehension by *seeing* what actually happens in all the incorrect methods of a task.
This was so much fun to watch👌🏾💯
Curiosity rules! 🫶🏾👏🏾
Yup, curiosity is what drove me to try all of this :)
I like it.
Picasso
LoL "Picasso" is too generous
what about TRICLAD as an intermediary metal?
Not something I've tried...but interesting idea
@@SomeGuysGarage I'm also wondering about laser welders, supposedly very easy to weld aluminum with them, not sure if it will fuse the aluminum with steel though. Also interesting if you had rusty iron powder along wtih aluminum powder you'd have basic thermite and would not be able to put it out: Fe2O3 + 2 Al → 2 Fe + Al2O3
@@Turbo_Tastic unlikely on the thermite side of things, the metals won't fuse together.
Laser welding is awesome though!
I just want to see what will happen too. If it worked, you'd see it all the time.
Yup, it's known not to work, but I wanted to see it first hand.
I plan to do a follow up with pure argon shortly, is there anything else you'd like to see me try?
E for effort but without 100% argon the aluminum will never flow fluidly and 100% argon makes the steel weld pool lumpy and cools brittle.
Physic experiments are fun though.
For sure, it was definitely just a learning exercise and I'll need to pick up some 100% argon to play with next :)
An Austrian Company invented Alu Iron Welding ,they tried 10 Years for a success But in the End they Done it.
You Welders.all know the Company, Fronius
Mr Fronius got also very old around 100 and died 2014.
There are ways (explosively) to fuse them...just not really any practical welding options that I'm aware of.
@@SomeGuysGarage
From the Austrian Fronius Webpage If you translate it to english you may find what you are looking for..
" cold mig - Mag - Welding "
Das „kalte“ MIG/ MAG-Schweißverfahren CMT ist besonders vielseitig und eignet sich zum Fügen dünnster Bleche genauso wie für Wurzelschweißungen an Pipelines. Der Anwender erzielt darüber hinaus auch beim Fügen unterschiedlicher Materialien - zum Beispiel Stahl und Aluminium - hervorragende Ergebnisse.
U talk to much!
too*
lol but thanks for the feedback
