POST WELD Heat Treatment
"PWHT"
WHAT IS POST WELD HEAT TREATMENT?
Post Weld Heat Treatment (PWHT) is a thermal processing technique employed on welded joints following the completion of welding operations. The primary objective of PWHT is to mitigate residual stresses introduced during the welding process and to enhance the mechanical properties of the material, particularly its ductility and toughness. This process entails heating the welded region to a predetermined temperature, maintaining that temperature for a specified duration, and subsequently allowing controlled cooling.
