概要
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 confirm the usefulness of the developed numerical model. Except for the weld penetration shape, the analytical results of the bead surface shape and the temperature distribution, such as the Ac1 lines, were in good agreement with the experimental results. The developed model has the potential to be effective and more precise in predicting and evaluating properties such as the metallographic structure and the hardness of the HAZ during temper bead welding.
