When the vaporization appears on the material surface,the laser welding is in the critical condition between thermal-conduction welding and deep-penetration welding,and the simulated laser power density equates with the lower critical power density of laser deep-penetration welding at a given welding speed.
当材料表面刚好出现气化时,激光焊接处于热传导焊与深熔焊之间的临界状态,此时,模拟的激光功率密度就是特定焊接速度下激光深熔焊接的下临界功率密度,可以用激光焊接的热传导模型进行模拟。
