Working principle and application industries of automatic laser welding machine

In the industrial laser industry, there are many types of laser equipment, and Laser welding equipment can be said to be the easiest and most complicated one. The automatic Laser welding machine is an efficient and precise welding method which uses high energy density laser beam as the heat source. Its application range is very wide, such as: camera module, VCM, hard disk magnetic head, optical communication components, thermal elements, photosensitive elements and other products which traditional welding methods are difficult to solder.

Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser spreads through heat conduction to the inside of the material, melting the material to form a specific molten pool. It is a new type of welding, laser welding is mainly for the welding of thin-walled materials and precision parts, it can implement spot welding, butt welding, stitch welding and sealing welding.

The automatic laser welding machine can change the output waveform of laser energy according to the shape and material of the workpiece during the welding process of the specific workpiece, which can greatly improve the welding quality. Even some traditional laser welding problems can be solved by changing the output waveform of the laser.

The automatic laser welding machine of Shenzhen Sun Laser Technology Co., Ltd. has small heat-affected zone, little deformation, fast welding speed, smooth and beautiful weld seam, high weld quality and no porosity, no need further treatment after welding or only simple processing is needed. It can be precisely controlled, with small focusing spot and high positioning accuracy. It is widely used in mobile phone communication, electronic components, glasses and clocks, jewelry, hardware, precision equipment, auto parts and other industries.
