Dear Bhatti,
First you tell me what is the material you have selected to use as a support and what is the thickness for the support material.
If your WPS is qualified with PWHT you have to do the PWHT.
If PWHT is service requirement you have to do PWHT.
Other cases you have to follow construction code (unless otherwise specified in client std/specification).
Regards
