Welding Stainless to Steel

Welding Stainless to Steel

Welding Stainless to Steel

(OP)
I need to weld some 304 stainless to AR steel.

I plan to use ER70S-6 wire and 75/25 gas.

This will be a fillet weld and will not be a load bearing weld.

I have been told that this will crack and fail,  What are your thoughts?

RE: Welding Stainless to Steel

You should NOT use this filler metal for joining 304 to AR plate. The AR (abrasion resistant) plate is a low alloy steel, and using a carbon steel filler metal, such as ER70S-6, will result in cracks after solidification.

You need to use either ER 309 or Inconel (Ni-base filler metal).

RE: Welding Stainless to Steel

There is nothing to add when the answer is correct and complete.
Use 309.

RE: Welding Stainless to Steel

Is calculation of the strength of the weld the same as AISC provides except using the properties of 309 for this application?
