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.

Laser welding machines, also known as laser welding machines, energy negative feedback laser welding machines, laser welding machines, laser welding machines, laser cold welding machines, laser argon welding machines, laser welding equipment, etc. According to their working methods, they can often be divided into laser mold welding machines (manual laser welding equipment), automatic laser welding machines, jewelry laser welding machines, laser spot welding machines, fiber optic transmission laser welding machines, galvanometer welding machines, handheld welding machines, etc. Special laser welding equipment includes sensor welding machines, silicon steel sheet laser welding equipment, keyboard laser welding equipment.
