Dear Experts,

Is interpretation: IX-01-17 is still valid, if not, then how it affects this interpretation.

Intepretation: IX-01-17

Background: A groove weld procedure qualification test coupon 1.5 in. thick was welded with SMAW process using multiple passes of 1/2 in. thickness. The coupon was given a subsequent PWHT exceeding the upper transformation temperature prior to the completion of mechanical testing .

Question: May this PQR be used to support  the weld of partial penetration groove welds per QW-202.2(b) or weld repair and build-up welds per QW-202.3(b) on base material thickness exceeding 1.65 in.

Reply: No. Per QW-407.4, a procedure qualification test coupon receiving a PWHT in which the upper transformation is exceeded, the minimum qualified thickness for production welds is 1.1 times the thickness of the test coupon.

Regards,

Aslam Khan
