You can weld a wide range of stainless steels from 300 series stainless steels.
Welding stainless steel to mild steel.
For other stainless steels or for welding to higher strength carbon steels you can use 312 stainless which by the way also has a tensile of 120 000 psi and is a lot cheaper than the weld all alloys sold by companies like magna.
Resistance welds can be completed incredibly fast since resistance welding works by passing electricity through a.
Every wielder wants whatever they are fabricating to come out good.
Things you need to consider.
And that is how it should be.
Welding stainless steel to mild steel.
All the way up to series 309 stainless steel.
309l is often used to weld 304 stainless to mild steel.
Welding materials are quite expensive these days so one needs to be extra careful and ensure whatever is being fabricated is done to the required standard.
After reading these posts i decided to weld it up with 308 filler all the stainless stainless pieces and then autogenous welded the mild steel to stainless around the inside of the flange.
309l is ideal to join your stainless steel to mild steel because this welding wire is made to weld both metals.
