Post Weld Heat Treatment Furnace

• The firm specialises in providing quality post weld heat treatment furnace/ post weld heat treatment services (PWHT), which is one of heat treatments done after welding/machining to improve the chemical/ mechanical properties of weldment / machined surfaces.
• In steel fabrication, the most common procedure used is stress relieving, which reduces the residual stresses formed during welding. It also restores the macro structure of the steel.
• PWHT eliminates these effects by heating, soaking, and cooling the weld area in a controlled manner to temperatures below the first transformation point, giving the macro structure sufficient time to readjust to its original state and removing the residual stress.
