Dissimilar metal welding with 316 SS wire
Dissimilar metal welding with 316 SS wire
(OP)
I currently have a project where we are welding 304 ss and 316 ss to carbon steel. This is a lower temp application so I specified a WPS with 309 filler. After PMI on several of the weld it was discovered the wire was marked 309 but was actually 316 ss. What potential problems do I have with these welds?

I find this hard to believe. Are you sure about the above? Did you run bead on plate using the so-called mislabeled 309 rod using PMI to confirm a 316 stainless steel composition? Otherwise, the PMI results may be misleading if you are testing completed butt welds. I have seen strange PMI results from folks that were not qualified to operate an alloy analyzer. If 316 stainless steel filler metal was used by accident, I believe someone just picked up a wrong can of filler metal.
