I am fairly new to procedure writing and am still fumbling my way through the interpretation aspects of things. Currently, I am reviewing a customer who had an inspector kick back one of our procedures that was written to D1.1:2015. One of the markups was the fact that we listed multiple electrode diameters for the pWPS. Based off of pWPS Essential Variables in 3.7, item #7, I interpret that as a change outside of what we decide to list on the procedure requires re qualification. The inspector is saying we need a separate WPS for each diameter. Same thing with base metals. On the pWPS we list that AWS Group I and/or II may be used, and the inspector is saying we need to be specific with Spec and Type and Grade based off of 3.7, item #3. I interpret this the same way as I am interpreting filler metals.
Thanks in advanced!
