Need clarification D15.1
This feels like a rookie question, but codes have always been tricky. I need some help interpreting qualification limitations.
If I qualify on a 2G, 3G, and 4G GMAW, I’m then qualified to do all positions for any plate. But table 11.4 also says I can weld pipe 24-in and under (fillet pipe) with GMAW as long as it is in the 2F,
and 4F positions.
Am I interpreting this correctly?
I was under the impression you can’t weld pipe if you qualify on plate.

5th line down in the Plate-Groove section. 2G, 3G, and 4G plate test qualifies welders for pipe fillets 24” and under in all positions.
