rogue male Posted November 3, 2005 Report Share Posted November 3, 2005 Hmm I don't think that's possible. The two metals are so dissimilar. If you could manage to stick them together the bond would be very weak and probally fall apart before you could use it. Quote Link to comment Share on other sites More sharing options...
Tinman Posted November 3, 2005 Report Share Posted November 3, 2005 It is possible, never recommended though. There may be other ways to do what yotaman is trying to accomplish. fel free to PM me with what you need done yotaman, I'll come up with some solutions.

Broken_Wankel Posted November 4, 2005 Report Share Posted November 4, 2005 I've never seen it done before. You have to run a shit load of amps on aluminum to get rid of the oxide cover. Even on thin shit you would have to run upwards of 150 amps. Two completely different metals, require two completely different filler metals. I guess you could try to use no filler, or try to braze it...don't think it's possible to make a good sound weld regardless though. Let me know what you do tinman...I'm curious.

ShoMeSomeFun Posted November 4, 2005 Report Share Posted November 4, 2005 normally when you want to weld something they HAVE to be the same metal, it might hold but it wont work for long it wouldnt be safe for any application, ive tried welding cast aluminum back toghether on my tranny just broke openen aluminum to soft to weld unless its forged and steel is much harder so it wouldnt be a good idea, my .02 cents.

Broken_Wankel Posted November 4, 2005 Report Share Posted November 4, 2005 I remebered somthing while I was working out. You run aluminum on AC, and other steels with DCEN. So, I don't see how a good sound weld could possibly be made. Quote Link to comment Share on other sites More sharing options...
Trouble Maker Posted November 4, 2005 Report Share Posted November 4, 2005 it might hold but it wont work for long it wouldnt be safe for any application Umm, part of the power that is running your computer right now is very contrary to that statement.

Cast aluminum is very easy to weld. All it takes is the proper equipment, preperation, and knowhow. Also cast aluminum is not soft, it is actually harder than the T2 material used most most aluminum sheet fabrication. It is brittle however, that's why it tends to crack.

And it needs to be CLEAN or your fucked. I have welded several bellhousings,a nd uber turbo inlets/outlets which are all cast, and as long as its cleaned properly its NBD.
