![]() ![]() ![]() This improves the performance of the weldment/machined surface. ![]() PWHT reduces or redistributes the residual stress introduced by the welding process by heating, soaking and cooling the weldment/machined surface to a controlled temperature. PWHT requirements may also be present based on the wall thickness of the components that are welded together. Post-weld heat treatment (PWHT) machine to improve the microstructure of the weld and reduce residual stresses generated during the welding process.Our company specializes in PWHT for the steel and metal processing industries, including pressure vessels, pressure pipes, storage tanks, buildings, bridges, offshore platforms, power plants, oil and gas refineries and petrochemical plants.PWHT is usually mandatory due to compliance with welding specifications and specifications for certain materials, including but not limited to carbon steel, stainless steel/high alloy steel and work hardened steel. ![]()
