2. Welding Procedure Specification - Wikipedia

   en.wikipedia.org/wiki/Welding_Procedure...

   The American Society of Mechanical Engineers (ASME) similarly defines a WPS as a written document that provides direction to the welder or welding operator for making production welds in accordance with Code requirements. [2] ASME also defines welding PQR as a record of variables recorded during the welding of the test coupon. The record also ...

3. Welder certification - Wikipedia

   en.wikipedia.org/wiki/Welder_certification

   Welder certification is based on specially designed tests to determine a welder's skill and ability to deposit sound weld metal. The main part of the welder's test consists of welding one or more test coupons which are then examined using non-destructive and destructive methods.

9. Post weld heat treatment - Wikipedia

   en.wikipedia.org/wiki/Post_weld_heat_treatment

   Industry codes, such as the ASME Pressure Vessel and Piping Codes, often require mandatory performance of PWHT on certain materials to ensure a safe design with optimal mechanical and metallurgical properties. [2] [3] The need for PWHT is mostly due to the residual stresses and micro-structural changes that occur after welding has been ...
