Can anyone share the section in API 1104 that states that you have to have a PQR and a WPS for a legal welding procedure? Would a WPS and procedure test coupons be OK?
When testing welder to API 1104, is the material an essential variable? Can I give them a 12" butt and branch test with Grade B STD wall pipe, 6010 downhill all the way and they be good for all thicknesses and diameters and grades? The reason why I'm asking is we are welding Grade B pipe all...
