PWHT/Stress Relieving Heat Treatment Service

There is often a mandatory requirement for PWHT due to compliance with welding codes and specifications on certain materials including but not limited to carbon steels, stainless/high alloy steels and work hardened steels. There may also be PWHT requirements based on the wall thickness of the parts being welded together. PWHT reduces or redistributes the residual stress introduced by the welding process with a technique that involves heating, soaking and cooling the weldment/machined surface to controlled temperatures. This improves the properties of the weldment/machined surface. Other benefits of PWHT include: * Improved ductility of the material * Improved or reduced hardness * Reduced risk of brittle fracture * Relaxed thermal stress * Tempered metal * Removal of diffusible hydrogen (to prevent hydrogen induced cracking) * Improved metallurgical structure
