The Importance of Correct Post Weld Heat Treatment (PWHT
Post Weld Heat Treatment is a mandatory requirement for the fabrication and construction of pressure vessels. The residual stresses formed during welding can cause metal failures. The macro structure also changes during the welding process and makes the steel weak. PWHT removes these stresses and restores the macro structure of the steel.
