Abstract
(EN)
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).
(FR)
L’invention concerne un dispositif de soudage au laser (1) comprenant une fenêtre de passage de laser (20) et une buse d'injection de gaz (6b). La buse d'injection de gaz (6b) comprend : un trou de trajet optique (161) ; et une partie d'injection (162) qui injecte un gaz inerte destiné à protéger une vapeur métallique dans le trou de trajet optique (161), le gaz étant injecté vers la direction de projection (E) de la lumière laser (L) et également vers un axe optique (A).
(JA)
このレーザ溶接装置(1)は、レーザ透過窓(20)と、ガス噴射ノズル(6b)とを備える。ガス噴射ノズル(6b)は、光路孔(161)と、レーザ光(L)の照射方向(E)側でかつ光軸(A)側に向けて、金属蒸気をシールドするための不活性ガスを光路孔(161)内に噴射する噴射部(162)とを含む。
