I am preparing to run a new PQR plate using Base Metal M270 Grade 50 Type 2 SAW process.
Per Table 4.1 (pg 77) my SAW Electrode Specification should be AWS A5.17.
Question Can I use a SAW filler metal that is per AWS A5.23 with this base metal?
I think the answer is no, I'm limited to AWS A5.17 for grade 50, and AWS A5.23 shall be used for base metal HPS 485W. But if I am qualifiying the procedure why can't I mix and match as needed.
Thanks Chris
