Product Details

Stress Relieving:
By the time it's complete, the welding process can leave a large number of residual stresses in a material, which can lead to an increased potential for stress corrosion and hydrogen induced cracking. PWHT can be used to release these residual stresses and reduce this potential. This process involves heating the material to a specific temperature and then gradually cooling it.Heat is usually held for one hour per inch of thickness of the metal. Holding temperatures can range from 593-732°C.
