The laser welding machine has a high degree of automation and the welding process is simple. The non-contact operation method can meet the requirements of cleanliness and environmental protection. Using laser welding machines to process workpieces can improve work efficiency, resulting in beautiful appearance of finished workpieces, small welding seams, large welding depth, and high welding quality. Laser welding machines are widely used in the processing of dental dentures, keyboard welding, silicon steel sheet welding, sensor welding, battery sealing cover welding, and other aspects. However, the cost of laser welding machines is relatively high, and the accuracy requirements for workpiece assembly are also high, which still have limitations in these aspects.
