In this study, a predictive simulation model coupling weld bead formation and thermal conduction was developed for construction of the method of predicting or evaluating the temperature distribution during temper bead welding. Welding parameters used in the analysis were estimated from experimental welding conditions based on the thermal conduction theory and numerical simulations of previous works. The simulation results were compared with the experimental results under the same welding conditions to ...

Inconel 600 alloy, Ni base alloy, and SUS304 steel, austenitic stainless steel, are used for steam generators tubing, pressure vessel, etc. due to its high strength and high corrosion resistance. Stress corrosion cracking is attributed to sensitization at grain boundary occurs and it causes failures in plants. Though these alloys are paramagnet, they transforms into ferromagnetic along grain boundaries when sensitization occurs. Therefore nondestructive evaluation using magnetic measurement for sensiti...
