About this document
Post-Weld Heat Treatment Procedure by ScribdTranslations is a document available to read on EtoBox.
The document describes procedures for post-weld heat treatment (PWHT) with the objective of relieving residual stresses introduced during the welding process. PWHT involves uniformly heating the weld zone to a temperature below the critical point of the metal and then uniformly cooling to improve mechanical properties and reduce defects. The document specifies the methods of heating by electrical resistance or induction, as well as the temperature and time parameters required.
