PWHT stands for Post Weld Heat Treatment, a process used to relieve residual stresses and improve the mechanical properties of welded joints. PWHT involves heating the welded joint to a specific temperature for a certain amount of time, followed by controlled cooling. The process helps to reduce the risk of cracking, improve toughness, and enhance the overall integrity of the weld. Common applications of PWHT include pressure vessels, pipelines, and structural steel components. PWHT is often required by codes and standards to ensure the quality and reliability of welded structures.
