Welding Stainless Steel To Mild Steel

All the way up to series 309 stainless steel.

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. 309l is often used to weld 304 stainless to mild steel. Due to its high resistance to current flow heat at the weld joint is generated easier and quicker than mild steel. 309l is ideal to join your stainless steel to mild steel because this welding wire is made to weld both metals.

Things you need to consider. 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. On the outside i put three evenly spaced 1 2 long welds using 308 filler. Using a resistance weld for stainless steel welding is an easy smoother process when compared to other metals.

Every wielder wants whatever they are fabricating to come out good. Welding stainless steel to mild steel. You can weld a wide range of stainless steels from 300 series stainless steels.
