Can you weld stainless with a regular old ac/dc arc welder? We were able to weld up some mild steel exhaust piping with it, but i'm looking a stainless piping and need a way to weld flanges on it. Do you need special rod for stainless? What about going stainless pipe to mild flanges?

 

you can weld stainless with stainless weld rodim not to sure of the weld rod number. and im not 100% posative but im pretty sure you cant weld stainless to mild steel. but dont take my word for it

 

You can weld stainless to mild as long as you are using the proper rod

 

Thanks guys. I"m lookinga welding stainless pipes, but the flanges I can get are only in mild steel. Do you know what kind of rod I would need to do it?

 

309L for welding stainless to mild steel

 

thanks for the help guys
