Q38. May a welder who is qualified using a double-groove weld, make a single V-groove weld without backing? A. Yes B. No C. Not enough information provided D. Yes, because backing is not an essential variable for a welder ANS: b Q39. May a GTAW welder be qualified by radiography, in lieu of bend tests? The test coupon will be P-22 material and the production welds will be P-22 also. A. Yes B. No C. Not enough information provided D. Yes, provided the P-22 is welded with F-22 fillers ANS: b Charlie Chong/ Fion Zhang
QW-304 Welders Except for the special requirements of QW-380, each welder who welds under the rules of the Code shall have passed the mechanical and visual examinations prescribed in QW-302.1 and QW-302.4 respectively. Alternatively, welders may be qualified by volumetric NDE per QW-191 when making a groove weld using SMAW, SAW, GTAW, PAW, and GMAW (except short-circuiting mode for radiographic examination) or a combination of these processes, except for P-No. 21 through P-No. 26, P-No. 51 through P-No. 53, and P-No. 61 through P-No. 62 metals. (note: P-2X/P-5X/P-6X) Welders making groove welds in P-No. 21 through P-No. 26 and P-No. 51 through P-No. 53 metals with the GTAW process may also be qualified by volumetric NDE per QW-191. The volumetric NDE shall be in accordance with QW-302.2. A welder qualified to weld in accordance with one qualified WPS is also qualified to weld in accordance with other qualified WPSs, using the same welding process, within the limits of the essential variables of QW-350.
