Tell, it is possible to weld a material SA-312 TP 304, electrodes – E 308L; E 308 MoL; E 309L; E 309 MoL? Or not?

mageslay,

First, how is your WPS written?
Second, is your PQR listed the above electrodes to qualify your WPS?

mageslay, agreeing in part with the other post however more specific to your question, any of the fillers you mentioned would be okay for welding the material in question. Normally, a company would lean towards using the 308 alloy as it is slightly less expensive.

I only agree in part with the other responses as change in classification is only an essential variable when notch toughness is required. Whether notch toughness is required is defined within your constructing codes but in the case of austenetic stainless steels, many codes exempt these, but good to check!

WPQ and PQR at me is not present. A question purely theoretical =)
