More Information
Summary:This laser welding device (1) comprises a laser pass-through window (20) and a gas injection nozzle (6b). The gas injection nozzle (6b) includes: an optical-path hole (161); and an injection part (162) that injects an inert gas for shielding a metal vapor into the optical-path hole (161), the gas being injected towards the projection direction (E) of the laser light (L) and also towards an optical axis (A). 本发明的激光焊接装置(1)具备激光透过窗(20)以及气体喷嘴(6b)。气体喷嘴(6b)包含光路孔(161)以及喷射部(162)，上述喷射部(162)朝向激光(L)的照射方向(E)侧并且朝向光轴(A)侧，将用于屏蔽金属蒸气的惰性气体喷射至光路孔(161)内。
