DR-HJ60 laser spot welder does the materials welding by using the high-energy laser pulses. First, the pulse laser power excites xenon lamp to light it, and makes it in a pre-ignition state. Then the control system controls the laser power supply so that xenon lamp pulse discharge power and produces light waves with certain pulse width. Passing through the cavity, the beam will radiate to the ND: YAG laser crystal, making the working material radiate by stimulation. After a laser resonant cavity resonance, it will discharge laser with a certain wavelength. Laser can weld the object immediately after expanding, reflection, and focusing. It is suitable for spot welding, seam welding, repair welding and other kinds of welding on various metal materials
