Welding stainless to mild steel exhaust.

They make a 309 wire this is for welding carbon steel to stainless steel only. By using tig welder you can use the right heat to weld the exhaust pipe and get the best welding result. But for much thicker stainless steel a faster wire feed speed is required to create a larger welding pool.

You can weld a wide range of stainless steels from 300 series stainless steels. Its definitely not a good idea. These include the mechanical properties chemistry and ability to resist corrosion as taking the right decision can prevent any trouble that might creep in overtime. Since its just a crack on a car exhaust i think 308 or 316 would be fine to use but it s up to you.

I would get some 3 32 and some 1 16 wire i don t know the material thickness or if their is a gap but these two sizes should cover it. Focus on the properties of the metals you intend to weld.
