最近,法国焊接学院研究出一种激光微型焊接技术,焊接的金属厚度范围从1到几毫米。激光器分别采用350W CO_2激光器和30OW的固态钇铝柘榴石激光器。由于钇铝柘榴石激光的能量密度高,所以在相同穿透能力等级条件下,钇铝柘榴石激光使金属产生的变形比CO_2激光小,它的脉冲发射结果导致了焊接速度低,但简化了对中问题。因此,在严格控制主要因素的情况下,可认为钇铝柘榴石激光器优于其它类型的激光器。法国焊接学院曾分别在
Recently, the French Welding Institute developed a laser micro-welding technology, welding metal thickness ranging from 1 to several millimeters. The lasers use a 350W CO 2 laser and a 30OW solid-state yttrium aluminum garnet laser, respectively. Due to the high energy density of yttrium aluminum garnet lasers, the yttrium aluminum garnet laser produces less deformation than the CO_2 laser with the same penetration level, and its pulse emission results in a low welding speed but simplifies The question of alignment. Therefore, Yttrium aluminum garnet lasers can be considered as superior to other types of lasers with strict control of the main factors. France Welding Institute had respectively
