Q. Explain about Post-weld Heat Treatment?

Post-weld Heat Treatment (PWHT) shall be in accordance with the Code. PWHT procedures, including properly identified charts or certified time-temperature line diagram shall be submitted to WorleyParsons Canada for review and approval.

Unless otherwise stated on the boiler data sheets, the rates of heating, cooling and holding temperature shall be as per the Code.

After PWHT is performed the equipment shall not be deformed by mishandling, storage, assembly or other procedures.
