Hi, 4.1 refers to only the position that is qualified.
For groove joint qualification you have to refer to 4.13. for tubular connections and 4.10 for non tubular connections.

Dear Experts
Table 4.1- WPS/PQR Qulafied x Production Weld Position Qualified Range.
Note "b"- Qualifies for circumferential welds in pipes equal to or greater than 24 in [600 mm] nominal outer diameter
Question - Does "circumferential welds" means only CJP/PJP-girth and seam butt weld joint on inclusive of fillet weld joint,: for example Pipe welding to a base plate?
In my opinion only apply for "only girth and seam butt CJP/PJP weld joint".
My understanding- WPS/PQRs qualified in any of these 1G/2G/3G/4G position(s) can be used to weld any diameter of Circumferential Fillet weld.
Pls advise
