激光焊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，产生热能，熔化工件(见图)。激光束是具有单一频率的相干光束，在发射中不产生发散，可用透镜聚缩为一定大小的焦点（直径为 0.076～0.8毫米）。小焦点激光束可用于焊接、切割和打孔；大焦点激光束可用于材料表面热处理。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。如采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、钕玻璃等。固体激光器输出能量小,约为1～50焦耳,产生脉冲激光,其加热脉冲持续时间极短(小于10毫秒)，因而焊点可小到几十至几百微米，焊接精度高,适于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，固体激光器广泛用于焊接微型、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氩离子气等,功率大(15～25000瓦)，可产生连续激光,能进行连续焊接,可焊0.12～12毫米厚的低合金钢、不锈钢、镍、钛、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）
