Folks,
Other considerations.
1. The welding process and material (s) are not specified. Welder qualification for GMAW-S via RT is not permissible, as well for some materials...see ASME IX QW 304 that follows:
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.
Deekee,
Appreciating your reference, it indicates the entire weld circumference needs to be examined. It doesn't specify that the entire weld needs to be made by a single welder.
Just my 2 cents..
