YAG laser welding uses a high-energy pulsed laser to weld the workpiece. It uses a pulsed xenon lamp as the pump source and ND:YAG as the laser working substance. The laser power supply firstly pre-ignites the pulsed xenon lamp, discharges the pulsed xenon lamp through the laser power source, and causes the xenon lamp to generate light waves of a certain frequency and pulse width, and the light wave irradiates the ND:YAG laser crystal through the concentrating cavity, thereby exciting the ND:YAG laser crystal to generate laser light. After passing through the cavity, a pulsed laser with a wavelength of 1064 nm is generated. After the laser beam is expanded, reflected (or transmitted through an optical fiber), and focused, it is radiated to the surface of the workpiece to partially melt the workpiece to achieve welding. The pulse laser frequency, pulse width, table moving speed, and moving direction required for welding can be controlled by PLC or industrial PC, and the laser energy can be controlled by adjusting the magnitude of the current, the frequency of the laser, and the pulse width.
