    • A laser processing system and a laser processing method that can highly accurately and efficiently specify a focus position of a processing laser using visible lasers are provided. For that purpose, a laser processing system includes a processing laser oscillator, a condensing optical system including a condenser lens, two visible laser oscillators and, a movement adjusting unit that adjusts the condenser lens and the visible laser oscillators and to move forward and backward in synchronization with each other, an imaging unit that images spot lights of the visible lasers on a workpiece, an image processing unit that subjects an imaged video to image processing and displays an image after the processing, a calculating unit that calculates, in a state in which the respective visible lasers are focused on a focus position of the processing laser, center of gravity positions of spot lights of the respective visible lasers formed on the surface of the workpiece according to the movement of the condenser lens and calculates a distance between centers of gravity, and a control unit that controls the movement adjusting unit such that the distance between centers of gravity is adjusted to zero or substantially zero.

    • A powder metal cladding nozzle which is coaxially attached to a laser processing head that irradiates a process portion (W) with a laser beam (L) and that discharges powder metal (P) to a laser beam irradiation portion in the process portion (W). The powder metal cladding nozzle includes a body portion (2) that has a ring-shaped powder metal holding space (7) in which the powder metal (P) is held; and a nozzle portion (3) that is connected to the body portion (2) and that has plural discharge passages (18) which are communicated with the powder metal holding space (7) and which open at an outlet (19) for discharging the powder metal (P). The powder metal holding space (7) is formed in the body portion (2) and is divided into plural powder metal holding regions corresponding to plural supply passages (10) that open into the powder metal holding space (7) and that supply the powder metal (P) to the powder metal holding space (7).
    • 一种粉末金属包覆喷嘴,其与激光加工头同轴地安装,激光加工头用激光束(L)照射处理部分(W)并将粉末金属(P)排放到处理部分(W)中的激光束照射部分, 。 粉末金属包覆喷嘴包括:主体部分(2),其具有保持粉末金属(P)的环形粉末金属保持空间(7); 和与主体部分(2)连接并且具有多个排出通道(18)的喷嘴部分(3),它们与粉末金属保持空间(7)连通并且在出口(19)处打开以排出 粉末金属(P)。 粉体金属保持空间(7)形成在主体部分(2)中,并被分成多个粉末金属保持区域,该多个粉末金属保持区域对应于向粉末金属保持空间(7)开口的多个供应通道(10),并且供应粉末 金属(P)到粉末金属保持空间(7)。
