Post weld heat treatment (PWHT) reduces residual stresses and improves toughness for both parent metal and weld material, while simultaneously clearing away hydrogen build-up in the weld area. Most current piping and pressure vessel codes stipulate PWHT when material thickness surpasses an arbitrary limit, usually determined by both Charpy energy absorption and hardness requirements.
