Comment on Welder Qualification Test (Performance Qualification) by Jay

I don’t have a subscription to AWS D1.1 to confirm for myself so I am hoping you can answer. I am an ASME certified welder and the bulk of my experience is with ASME, of course being qualified to Sect. IX and I understand testing in the 6G position qualifies a welder for all positions, however I am on an AWS project where my structural welders are qualifying in 3 positions per AWS and I am being told that AWS does not allow for one all position test as ASME does so we are running 3 coupons each (flat, horizontal and overhead) to qualify for all position which takes more time. It it true that AWS does not allow for an all position like ASME does and would these three positions qualify an AWS welder for vertical up as well? Seems we are spending a lot of time testing that could be spent in production if we just tested once for all positions and I am wondering if I am being informed correctly that AWS does not allow it. Is this true? Thanks!
