WPS/PQR for joint design
WPS/PQR for joint design
(OP)
For TIG welding, according to Section IX, joint preparation is not an essential variable. But if the weld root open is much larger than in WPS or the bevel angle changed, do you need to prepare another WPS and using the same PQR?

RE: WPS/PQR for joint design
Using Section IX, QW-256, the above variables you mentioned are considered nonessential, meaning changes can be made without requalification.

While something may be permissible by code, welding beyond the limitations imposed by your procedures violates both the procedure and (more than likely) your quality control program.
