| Research Abstract |
In order to elucidate physical phenomena and control a residual stress, which is induced by thermal history of a welding, in laser welding, We developed the numerical simulation code which can be able to consistently evaluate laser welding processes, i. e. from laser irradiation to solidification process. As a result, thermal transport effects by the molten pool convection neglected in conventional study has been enabled. Therefore, toward the elucidation of welding phenomena and controlling a residual stress, the basis has been developed in this study.
