Record Number: 18-771
Subject Description: SC IX; QW-401.1 and QW-403.6 - Thickness Range Qualified for Impact Testing Standard Designation: BPV Section IX Par/Fig/Table: QW-401.1 and QW-403.6 Edition/ Addenda: 2017
Background:
A welding procedure qualification was performed on a 40 mm thick test coupon in 1G position by GTAW (10 mm) and SMAW (30 mm). Tension and bend tests were performed on the 40 mm plate.
A second welding procedure qualification was performed on a 6 mm plate in 3G position by GTAW and only impact testing was performed. A third welding procedure qualification was performed on a 6 mm plate in 3G position by SMAW and only impact testing was performed. All of the essential variables remained the same except for the coupon thickness.
Question:
May the PQRs listed above, support a WPS (GTAW+SMAW) for material requiring notch toughness with a qualified base material thickness range of 5 mm to 200 mm, GTAW weld metal thickness range 20 mm max. and SMAW weld metal thickness range up to 200 mm max.?
Reply: Yes.
My queries . Is it in order
