Dear Sir,
-- We conducted welder qualification at Karbala Oil Refinery Project as per ASME-IX 2013 Edition.
WPS details as follow
1. WPS qualified base metal- P1 to P1 Gruop all
2. WPS mentioned base metal thickness range- 5 to 26 mm
3. Process FCAW
WQT details
1. Joint design Single V butt joint with back weld(Root side back grind then weld)
2. Base metal SA283-C
3. Thickness 16.0 mm
4. Sequence of welding- Root pass>Hot Pass>Filling>Capping>Back grind & Back weld
5. Test position 2G & 3G
My client inspector say welder will qualified only for 2T & Pipe Diameter will qualify over 24" I want to clarify is he correct? For thickness qualified he mention about QW-404.30
However I will appreciate to you for clarify my problem.
Regards
Anamul
