The PWHT/Stress relief process is performed by heating to a temperature as detailed in the welding code for the appropriate material, and holding at that temperature long enough to achieve the desired reduction in residual stresses.

Having well-qualified PhD team, QIS has led Vietnam heat treatment market by researching and building PWHT Internet of things System.

INSPECTION SERVICES
