@ Krausen
the preaheat is required if the nominal thickness (weld thickness) is greater than 1.25", isn't it correct? so why would you think it is required?
Thank you for your reply but what about the UW-40(f)(5)(-f) that states the nominal thickness is the thickness of the weld at the point of attachment when a non-pressure part is welded to a pressure part? The weld thickness in (1) is 0.75" and it is less than 1.5" which requires PWHT (if...
Hi everyone,
I am trying to figure out whether PWHT (Post Weld Heat Treatment) is required per code for non-pressure parts welded to pressure parts under the following conditions:
The material is P1 Gr.1 for both the pressure part and non-pressure parts. PWHT is not required for service.
