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.

Laser welding is the use of high-energy laser pulses to locally heat a material in a small area. The energy radiated by the laser is directed through heat transfer to the internal diffusion of the material, melting the material and forming a specific molten pool. It is a new type of welding method mainly aimed at the welding of thin-walled materials and precision parts, which can achieve spot welding, butt welding, overlap welding, sealing welding, etc. It has a high aspect ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld seam, no need for treatment or simple treatment after welding, high weld quality, no pores, precise control, small focus light point, high positioning accuracy, and easy to achieve automation.
