摘要:
An underwater welding apparatus comprises: an underwater welding head (11) provided underwater and having, at its leading end, a nozzle section (16) from which laser light is emitted; a shied cover (18) formed of an elastic member and provided around the nozzle section (16) so as to form, at the leading end of the underwater welding head (11), a space where water is excluded by means of shield gas; and an expansion/contraction member (21) having a discharge hole for discharging water and shield gas containing metal dust particles from an inside of the shield cover (18), the discharge hole being increased in diameter as pressure inside the shield cover (18) rises, while being reduced in diameter as the pressure inside the shield cover (18) falls.
摘要(中):
本发明提供一种水中焊接装置,其特征在于,具备:水下焊接头(11),其在前端具有照射激光的喷嘴部(16) 由弹性部件形成并围绕喷嘴部分(16)设置的罩盖(18),以便在水下焊接头(11)的前端形成一个用保护气体除去水分的空间; 以及具有用于从所述防护罩(18)的内部排出水和含有金属粉尘颗粒的保护气体的排出孔的膨胀/收缩构件(21),所述排出孔的直径随着所述防护罩(18)内的压力而增大, 随着防护罩(18)内的压力下降而上升,直径减小。
