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

Regardless codes, your odds to succeed are minimal if you don not perform PWHT.
