POST WELD HEAT TREATMENT (PWHT)

In order to keep the strength of the material maintained after welding, a process called post–weld heat treatment (PWHT) is usually carried out. This process can be used to decrease residual stresses, as a means to control hardness, and enhance the strength of the material. If post–weld heat treatment is not performed correctly or overlooked, the residual stresses can strengthen the level of load stresses enough to exceed the material's design constraints. This might result in weld failures, higher susceptibility to the brittle fracture and crack potential

You don't need to worry about these problems as Innovative Heat Treatment Solutions is there to work hand in hand with you to avoid any delay, improper application or biased monitoring. The specialized post weld heat treatment team at Innovative Heat Treatment Solutions ensures the solutions to provide:

• Relaxation of residual stress
• Relaxation of thermal stress
• Tempering metal
