ASME B31.3 - ASME IX - PQR with PWHT & WPS without PWHT ?
(OP)
Hi everybody,
With ASME B31.3 as construction code and ASME IX as qualification code.
Could I use PQR with PWHT with a WPS without PWHT ?
The thickness range in the WPS don't require PWHT according to ASME B31.3.
NB: The other parameters in the PQR and WPS comply with ASME IX.
Thanks and excuse me for my bad english.

You will require separate PQRs - one with PWHT, one without.
See QW 407.1
