  • AbstractIntroductionReview of Current Practice and Code RequirementsPost-weld heat treatment (PWHT) is applied to steel assemblies primarily to reduce the likelihood of brittle fracture by reducing the level of tensile welding residual stresses and by tempering hard, potentially brittle, microstructural regions. For large steel assemblies in particular, PWHT can be an expensive operation, and there is thus an economic incentive to avoid PWHT, wherever possible. Whether PWHT is necessary depends on the fracture toughness at the minimum service temperature, the stress levels anArunsiddharth Kaliappan - Welding Engineer - Cutech Group About I completed B.E.-Mechanical Engineering and Post Graduate certification in Welding & Quality Engineering in BHEL.
