Re: [MW:8369] pwht thickness as per AWS D1.1

Hi, AWS doesnt require any PWHT.But if PWHT specified in Project specification,it shall be done as per AWS-Section 5.8 5.8 Stress-Relief Heat Treatment Where required by the contract documents, welded assemblies shall be stress relieved by heat treating. Final machining after stress relieving shall be considered when needed to maintain dimensional tolerances.
