API 1104 WPS's and AWS Filler Metal Classification
API 1104 WPS's and AWS Filler Metal Classification
(OP)
This is one of those "ask six different people and get six different answers" questions!
Section 5 of API 1104 (Welding Procedures) requires you to requalify a welding procedure on material 65 ksi and greater if you change a filler metal AWS Classification.
My question is:
Would changing from E8018-B2 to E8018-C3 be considered an AWS Classification change? Or are they implying you would only need to requalify if you were changing from a E8018 to a E9018?
Thanks in advance,
Mark

Based on the foregoing, one would conclude that the indicated classification difference is, in fact, a change of classification. The underlying reasoning is explained in the note under 5.4.2.2 of API 1104 which is particularly pertinent to high strength linepipe steel.

Yes.
That is also a change in classification.

Steve, thanks for the section in A5.5, that makes this issue crystal clear.
