mechanical test for wqt 1

[abangbikerz]

Is WQT test coupon does not need to be send for destructive test, enough on RT only. If it is can anyone point me any article in ASME IX on this requirement. Does QW-304 is the relevant one. Im not really sure

I assume with the abbreviation you mean welder performance qualification record. If so, please review

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.
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.
