The —led by Section IX of the BPVC—is the most respected and legally enforced welding code for pressure equipment worldwide. From a small air receiver tank to a nuclear reactor coolant line, compliance with ASME welding rules protects life, property, and the environment. Section IX The primary standard for welding under

Forgotten post-weld heat treatment (PWHT).

Many WPSs require PWHT to relieve residual stresses. Omitting PWHT invalidates the PQR. Develop a Quality Control System (written manual covering
