Dear Vadival,
You have to comply with the requirements of the design code, which in this case is ASME VIII Div 1. That determines the application requirements, not the material specification.

Subject: [MW:25854] PWHT reqmt for welds as per API 6D
Dear Experts,
I have a Groove weld joint of thickness 40mm. The standard i need to follow is API 6D..
Welding procedures qualified under ASME sec.IX without PWHT with a test coupon of 50mm thickness of material ASTM A516 gr.70..
API 6D states " PWHT shall be performed in accordance with the applicable material specification or design code"
My material specification is ASTM A516 gr. 70 and Design code is ASME Sec.VIII Div. 1
A516 standard doesnt states welding or PWHT requirement, whereas ASME sec.VIII states - thickness above 38mm PWHT is mandatory..
Can i take the material specification to justify for not performing PWHT..
Please advise
With regards and thanks
Vadivel M
