Mig welding stainless steel!, joining rice-pipes...:) Options

[fiid]

For the WRX engine - I bought a couple of aftermarket (read: RICE) exhaust components for cheap that I could modify to fit on the 914.

I remember reading (I think on here) that it's possible to weld stainless using a regular MIG welder and mild steel wire. Of course the weld will rust, but thats not too much of a concern. Will it actually work? What problems will I encounter. Should I just find someone with a tig and get them to do it?

Thanks in advance...

Mike, you can use WD40 as antisplatter spray. It doesn't smell near as bad. Most Ricey stainless stuff is probably 304. If you are welding 304 to 304 use the 308 rod. If you are welding 304 to 321 use the 308 for 321 to 321 use a 347 rod. To weld stainless to mild use a 309 rod. You can't weld stainless to stainless with a mild steel rod or wire. It will break.

In the end if this is the only stainless piece you weld, buying the stainless wire and the purge bottle will cost you more than getting some one to weld the two pieces together. You will probably pay something like 20$ ro have it done.
