A post weld heat treatment is performed to alleviate residual stresses, increase the strength, increase or decrease What is Post Weld Heat Treatment (PWHT)? | WELDING It is worth restating that any PWHT must be done according the specific code or standard that governs the fabrication of the structure or component. Even though PWHT is done after welding it forms part of the welding procedure specification (WPS) and clear instructions must be shown in this document on how to perform the PWHT. References:

But it also can be applied during welding to improve weld quality through grain refinement and stress reduction. In fact, applying the right vibration during welding can eliminate the need for PWHT completely, unless tempering of the heat-affected zone is required.
