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 has been widely used in the electronics industry, especially in the microelectronics industry. Due to the small heat affected zone, rapid heating concentration, and low thermal stress of laser welding, it has shown unique advantages in the packaging of integrated circuits and semiconductor device shells. In the development of vacuum devices, laser welding has also been applied, such as molybdenum focusing electrodes and stainless steel support rings, fast heating cathode filament components, etc. The thickness of elastic thin-walled corrugated sheets in sensors or temperature controllers ranges from 0.05 to 0.1mm, which is difficult to solve using traditional welding methods. TIG welding is easy to weld through, has poor plasma stability, and has many influencing factors. However, laser welding has a good effect and has been widely used.
