자유표면변형을 고려한 저에너지밀도 레이저 용접공정 해석
A study of low-power density laser welding process with evolution of free surface
초록
In this study, numerical investigation has been performed on the evolution of weld pool geometry with moving free surface during low-energy density laser welding process. The free surface elevates near the weld pool edge if
