The Importance of Correct Post Weld Heat Treatment

The Importance of Correct Post Weld Heat Treatment

Why Do We Need PWHT?Factors to ConsiderPWHT MethodsWelding is one of the most critical processes in the manufacture of pressure vessels like the boiler of a thermal power plant.The temperature of the molten weld pool during the process is in the range of 2000 deg C. The heat increase is rapid and instantaneous. When this small strip of molten pool cools down the shrinkage results in thermal stresses that are locked up inside the metal. This also can change the macrostructure of the steel. This is because: 1. The rest and bulk of the steel is.Post Weld Heat Treatment (PWHT) , InspectioneeringUnderstanding how steel can change and be manipulated is crucial to our ability to spot potentially harmful situations in the field. Whether it is a blade made too brittle or a weld that needs post-weld heat treat, knowledge is power.
