Hi all. Long time aluminum welding at our company, new to D1.2. I am a little confused on the WPS qualification and welder qualification tables. A CJP 1G plate WPS will not qualify a pipe fillet weld under 24" in diameter, but a welder that qualifies to the fore mentioned WPS would qualify to weld fillet welds on pipe or tubing under 24"? How does that work? I would appreciate any and all advice.
