hello
I want to weld two dissimilar materials (A312 TP316) to (ASTM A182 F11) by GTAW process select ER309L by schaeffler diagram.
I wonder if the choice is correct or that another type of filler recommend me?
I wonder where I can find a prequalified WPS stainless steel (P.No6 to P.No8)
Check the site of the AWS (http://pubs.aws.org/search?q=B2.1&page=01) and there are only (P.No8 to P.No8)
