All,
Thanks in advance for any input.  Need to qualify a welder for 1/2" diameter sched. 40, stainless 316. GTAW process. 6G position. ASME B31.3  Issues are coupons.  QW 452.1 says 1 root and 1 face.  Bandsaw the entire test piece, length, in half to obtain the two coupons?  Or should QW 304.1 (b) be used and have the welder perform 2 tests to get the coupons?  For a WPS to be used on small diameter, same, diameter is not an essential variable, thus 6" diameter is o.k.?
