Post Weld Heat Treatment Services (PWHT) is performed after welding/machining to improve the Chemical mechanical properties of weldment / machined surfaces. In concept, PWHT covers many different potential treatments. However, in steel fabrication, most common procedure used is Stress Relieving.
Machining and/or Welding induce stresses in parts. The bigger and more complex the part; the more the stresses.
Stress Relieving is done by uniformly heating- fabricated equipment or the vessel or vessel part to a sufficiently high temperature, but below the lower transformation temperature range, then subjecting it to a thermal retardation for a sufficient time depending upon the material thickness and then finally uniformly cooling it which is also of utmost importance.
