According to this, the welder should qualified above 2.5"(inch)O.D.... He should weld (qualified) upto unlimited outer dia of pipe.(O.D).But it should be differ from thickness of pipe.....
Thanks & Regards

--Dear Expert,
Please advise me (clear my doubt) if my 6G Welder can carry-out the work with the following info . My welder qualification is at 3.5" (OD)[WT=12.7mm]. While the actual work is 4"OD [WT=8.56 mm(Sch 80)].
I will allow my welder to carry-out welding with the concession of monitoring his progress by NDT-RT. How often do I take RT? (is it 10% of his weld joint as per BS and ASME std?) Please revert and advise. Thank you!
Respectfully yours,
Peter Paul
