Many piping codes use fracture toughness of weldments as the basis for waiving postweld heat treatment (PWHT) requirements locally; however, this method may not always apply across materials or applications. PWHT requirements for power piping material generally rely on the lower critical transformation temperature of its base metal. Welding Procedures Weldability for welded joints depends … <\/p>\n
