ASME B31.3 - ASME IX - PQR with PWHT & WPS without PWHT ?

[nacer16]

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.

nacer16,
You will require separate PQRs - one with PWHT, one without.
See QW 407.1

Kiwi is right, as usual. However, you can just make one long PQR coupon, and cut it in half after welding it out. PWHT one half, leave the other "as-welded".
