用激光束作为热源的焊接方法。焊接时﹐将激光器发射的高功率密度(108~1012 瓦/厘米2 )的激光束聚缩成聚焦光束﹐用以轰击工件表面﹐產生热能﹐熔化工件(见图 激光焊示意图 )。激光束是具有单一频率的相干光束﹐在发射中不產生发散﹐可用透镜聚缩为一定大小的焦点(直径为 0.076~0.8毫米)。小焦点激光束可用於焊接﹑切割和打孔﹔大焦点激光束可用於材料表面热处理。激光束可利用反射镜任意变换方向﹐因而能焊接一般焊接方法无法接近的工件部位。如採用光导纤维引导激光束﹐则更能增加焊接的灵活性。激光器分固体激光器和气体激光器。固体激光器所用材料为红宝石﹑釹玻璃等。固体激光器输出能量小﹐约为1~50焦耳﹐產生脉衝激光﹐其加热脉衝持续时间极短(小於10毫秒)﹐因而焊点可小到几十至几百微米﹐焊接精度高﹐适於0.5毫米以下厚度的金属箔片的点焊﹑连续点焊或直径0.6毫米以下的金属丝的对接焊﹐固体激光器广泛用於焊接微型﹑精密﹑排列密集﹑对受热敏感的电子元件和仪器部件。气体激光器所用材料为二氧化碳或氬离子气等﹐功率大(15~25000瓦)﹐可產生连续激光﹐能进行连续焊接﹐可焊0.12~12毫米厚的低合金钢﹑不锈钢﹑镍﹑鈦﹑铝等金属及其合金。小功率二氧化碳激光器还可焊接石英﹑陶瓷﹑玻璃和塑料等非金属材料。激光焊件质量高﹐有时超过电子束焊焊件的质量。激光焊机﹐特别是大功率激光焊机﹐成本高﹐效率甚低﹐一般只达5~10%﹐最佳为20%﹐穿透能力也不及电子束。但用激光束可在空气中或保护气体中焊接﹐比电子束焊方便。(见彩图 激光焊机 )
