A study on high power CO_2 laser welding (2nd report) -A Modeling of laser welding process-

摘要

As it is difficult to explain a high power laser welding process because of its complicated phenomena, a simple model rarely contains enough information to explain welded shape or penetration properties. In this report, by arranging several welding data which were obtained using several high power CO_2 laser resonators, a simple equation to assume the penetration depth has been considered. Also, high power laser welding phenomena have been tried to explain by using a conventional thermal conduction theory.
