The study on the verification of post-weld heat treatment (PWHT) and PWHT temperature assessment by using AC magnetization method was carried out. Simulated specimens of different PWHT conditions were prepared and their bulk electro-magnetic properties were investigated. The finite element analysis incorporating with magnetic hysteresis was carried out for the purpose of finding proper inspection conditions and evaluation parameters. The simulation showed that PWHT can be verified by the AC magnetization method, however, for PWHT temperature assessment, some new parameters should be considered.
