The laser welding machine has the advantages of high output laser power, stable energy, good beam mode, wide application range and convenient operation. The whole machine is beautiful, compact and reasonable. Advanced combined gold-plated reflective laser cavity technology is adopted to stabilize the laser power supply. At the same time, special beam mode selection and shaping technology are used to ensure high output power and excellent beam modeIt is a special equipment for spot welding and seal welding of metal materials. The whole machine runs stably and reliably with good welding quality, high efficiency, simple operation and convenient maintenance. It also has the function of automatic protection for misoperation, over temperature and under flow.
