What is Post-Weld Heat Treatment (PWHT)?

PWHT Machine
A heat treatment method called Post-weld heat treatment(PWHT) is used on welded materials to relieve stress, reduce stiffness, and enhance maechanical qualities. residual stress from welding frequently cause the material to crack, distort, or even break under operating conditions. By regulating the material’s temperature and cooling system , pwht helps to reduce these dangers.

PWHT MACHINE (FAQ)

Post-weld Heat Treatment(PWHT) is a heat treatment process applied to welded materials afer the welding process to relieve stresses, reduce hardness, and improve mechanical properties. welding often results in residual stresses within the material, which can lead to cracking, warping, or even failure under operational conditions. PWHT helps to mitigate these risks by controlling the material’s temperature and cooling rate.
A PWHT( Post Weld Heat Treatment) Machine is used to apply controlled heat to welded components to reduce residual stresses, improve material properties and prevent issues like cracking or distortion. i enhances the strength, toughness and durability of the welded joint, ensuring the material meets industry standards and performs well under stress. This process is essential in industries like oil & gas, aerospace and power generation to ensure the intergrity and lonegevity of welded structures.
Induction Heating means to produce the alternating magnetic field through induction coil after induction-heating equipment outputs high-frequency current to make the workpiece heated quickly. This Type of PWHT machine is highly effective for localized heating of smaller parts(induction Heating Machine)
