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
