Welding austenitic stainless steel to low carbon steel

Welding austenitic stainless steel to low carbon steel

Welding austenitic stainless steel to low carbon steel

(OP)
I am working in a light mechanical environment, so not structural.

I want to connect a spring made from austenitic stainless steel to a low-carbon mild steel bracket.

For the spring, I had in mind s302 or s304l (1.4310/1.4306).  Both materials are thin, i.e. 0.6mm.  The bracket can be any low spec., low carbon, mild steel.

Can I spot weld the materials, or is it best to tack-weld them?

This is only a test, and will be tested immediately, so there are no long-term corossioon issues.

I would appreciate a reply at your earliest convenience as this is a live and urgent project.

Thanks in advance

Dave

I would spot weld them.

Spot weld, but remember that you spring will be soft near the weld.  Make sure that the weld is far enough back that it won't see load.
