Local PWHT
PWHT, or Post Weld Heat Treatment, is a process in metallurgy that involves heating metal material after welding is completed. The primary objectives of PWHT are to reduce thermal stresses and improve the mechanical properties and strength of the material
Local post weld heat treatment (local PWHT) is usually performed for tempering and relaxation of residual stresses. Circumferential weld seams can be post weld heat treated by heating a band around the weld. Many factors have an influence on PWHT procedures and heated width is the most important parameter controlling the effectiveness of local PWHT However, the determination rules of this parameter are very different in the different codes.
