deMideon Posted May 11, 2004 Share Posted May 11, 2004 Ok that last post made me think about building my own exhaust out of stainless, but I will need to weld it. I only have a wirefeed welder. Can I use this to do it? Quote Link to comment Share on other sites More sharing options...
johnc Posted May 11, 2004 Share Posted May 11, 2004 Yes. You'll need the wire (304L, 321, or 347 .024" or .030") and straight Argon as a shielding gas. Depending on the welder, you might need a new liner and rollers. Cut up some lengths of tubing and practice, practice, practice. Quote Link to comment Share on other sites More sharing options...
deMideon Posted May 15, 2004 Author Share Posted May 15, 2004 Hmmm... I have a cheap welder. Always has done what I've needed, but it doesn't have gas, just wire. Will that still work? Quote Link to comment Share on other sites More sharing options...
Z-TARD Posted May 16, 2004 Share Posted May 16, 2004 I've never seen flux core stainless wire for the el cheapo mig units. I have a Campbell/Hausfield mig and the only stuff I can find for it is regular steel wire. I have a TIG setup at work though, so I can fit up stuff in my garage and take it to work to weld up. You could probably assemble the exhaust using sleeves and clamps from Auto Zone/ Pep Boys/ Kragen/ Etc. It might not look as good, but will still be extremely corrosion resistant, as well as "adjustable" for a perfect fit. I would definitely have the pipe right after the collector welded though, it would suck to have your new stainless exhaust dragging on the ground due to a loose exhaust clamp Mike Quote Link to comment Share on other sites More sharing options...
deMideon Posted May 16, 2004 Author Share Posted May 16, 2004 Well it sounds like I will be getting aluminized steel. Won't last as long but it's really cheap and I can do it myself and make it fit right and weld it! Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted June 9, 2004 Share Posted June 9, 2004 I thought you didn' have to use argon, that it was just recomended that you will just get slag on the weld. I'm gonna have to find that post again. Ed Quote Link to comment Share on other sites More sharing options...

Guest Phailure Posted June 9, 2004 Share Posted June 9, 2004 *n00b welding question* can you weld aluminized steel? as in... can you weld it like normal mild steel with a mig welder? Quote Link to comment Share on other sites More sharing options...
Drax240z Posted June 9, 2004 Share Posted June 9, 2004 Yes you can weld aluminized steel as normal with a MIG... just wire brush/grind off the aluminizing where you are welding, and don't breathe the vapours. Also, it's impressive what a coat of high temp paint will do towards prolonging an exhaust system... It's well worth it on any mild steel exhaust system that you want to last IMHO.

Nismo280zEd Posted June 9, 2004 Share Posted June 9, 2004 I agree... i bought some of the high temp paint they sell at walmart in the silver color.. painted it up almost 2 years now still lookn' good. only a little surface rust on the flanges where i take the exhaust off. So is the jury still out.. can you weld stainless with out argon? Quote Link to comment Share on other sites More sharing options...
