Qualification of welders
Qualification of welders
(OP)
Dear All,
I have question. Qualification of welders according to ASME IX Code QW-301.2. We want to qualify welders to a valid WPS, PQR with PWHT. Now the person who supervise welding of test coupons does he himself have to be certificated ASME code welder or can be welding instructor with expired certificate or QC welding Inspector also with expired certificate?
Thank you.

You also made the statement" We want to qualify welders to a valid WPS, PQR with PWHT."
A welder does not "Qualify To" a WPS. A welder uses a WPS during the qualification and may be qualified for only a portion of the WPS used during qualifcation OR above and beyond the ranges allowed for in the WPS.
I just wanted to clarify that statement as it is a common misconception regarding the qualification ranges of welders.
