RE: WELD N/P BKT AFTER PWHT
ucs-56 has pwht rules.
If the vessel has not been pwht for a special service, but rather for code thickness rules, you can weld this on after pwht as long as you do the following:
A. have user approval
B. have ai approval
C. write a procedure for welding after pwht to follow ucs-56
this is standard fabrication rules. Read the code please
