Welding Stainless To Mild Steel Exhaust

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.

Welding stainless to mild steel exhaust.

Your wire feed speed also plays a huge role in welding stainless steel with normal mig wire. If you re welding mild steel it s more comfortable to manage as you d use a lower wire feed speed. But for much thicker stainless steel a faster wire feed speed is required to create a larger welding pool. So the quick bottom line is that you can weld together with either mild steel filler wire or stainless wire.

All the way up to series 309 stainless steel. We have proof right here. By using tig welder you can use the right heat to weld the exhaust pipe and get the best welding result. Stainless exhaust is sometimes made from 304 stainless but there are also quite a few exhaust components that use 400 series stainless like 409.

Is it ok to weld stainless steel exhaust tubing with carbon steel mig wire. 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. You can weld a wide range of stainless steels from 300 series stainless steels. 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.

You can perform welding on stainless steel mild steel titanium aluminum exhaust pipes. 316 stainless is approx the same basic chemistry as plain steel except the 300 series stainles has additional 18 cr and 8 ni which is what makes it stainless. Its definitely not a good idea. The welds will rust more if mild steel but strength wise no concerns.

Firstly before you weld stainless steel to mild steel you need to consider the properties both metals have. 309l is ideal to join your stainless steel to mild steel because this welding wire is made to weld both metals. They make a 309 wire this is for welding carbon steel to stainless steel only.
