WPS T joint CJP according AWS D1.1

I’d check the qualified thickness range on the WPS/PQR before deciding. It’s not necessarily a matter of using a 16 mm WPS just because the main chord is 16 mm. The 60 mm flanges, joint configuration and CPJ details also need to be considered under AWS D1.1. I’d confirm that the procedure covers the actual joint and material thicknesses before using it.
