What would you recommend to weld Stainless steel with?

What thickness stainless are you welding? If it is sheetmetal thickness you may have a hard time with it since it burns hot. If it is thin and you really want to try MIG on it use flux core and a shielding gas to cool it down. If you give me the specifics of what you are doing I may be able to help a little more.

I have already welded and will splain. I had to make a sign frame and the client wanted it from 2"x 2" stainless tube. It came in 304 SS with a wall thickness of .188", Cut welded it and the client requested a clear coat since it was outside. 304 will rust if not protected. 316 has much better properties to resist stainless but I could not get in sq. stock. After it was welded & everything ground smooth. I noticed that the weld areas were a s;ightly different color/ I am using flux core with sheilding gas. My worries are that even thought the frame has a clear coat, the weled areas being made up of the mig wire, might rust of further discolor causing me to dig it up & replace it.

What wire and shield gas did you use? A CO2 mix will decrease corrosion resistance a little.

But th' WIRE is what may show corrosion. This was with an atmosphere tip? Why not use the 316 compatable or equivalent WIRE to do the job?!?

Mix is argon co2 and the reason I posted was to save me a little tile on searching. 316 Wire. There is such an animal?

Thanks you. Great link. How'd you get it to highlight like that? Does google do that automatically or is it a setting?

I did a copy/paste of the URL, is all. I don't think it had anything to do with the fact I'm on a Linux box to do it. /ubbthreads/images/graemlins/grin.gif
