I was recently told by a fairly reliable source that PWHT is an essential variable of an AWS D1.2 PQR/WPS. I agree that makes sense but I cannot find anything that tells me in D1.2 that PWHT is in fact an essential variable? Has anyone come across this before?
I know it is in just about every other code available but either I have over looked it or it is not a requirement of AWS D1.2.
We are running some PQR's on 6061 T-6 that will be used on parts that will be solution annealed and artificially aged back to T6.
