Laser welding is one of the important components of laser material processing. Laser welding is a precision welding technology that uses a high-energy beam as a heat source. It mainly uses a high-energy laser beam to heat the surface of the workpiece, and the heat diffuses from the surface of the material to the inside. By adjusting the various parameters of the laser pulse, the corresponding The material melts to form a specific molten pool.

The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. Laser tailor welding uses laser energy to combine materials of different materials, different thicknesses or different shapes to meet the requirements for material performance in different situations. 

The equipment can be realized with the lightest weight, the best structure and the best performance. Lightweight.

So, what are the advantages of laser welding machine in the field of thin plate welding?

Stainless steel materials are widely used in the manufacture of various finished products, and the welding of stainless steel sheets has become an important process in the production process. However, due to the characteristics of thin-plate stainless steel, it also caused certain difficulties in welding, and it once became a welding problem in the field of thin-plate stainless steel.

The traditional welding machine has a big problem in processing thin stainless steel. Because of its small thermal conductivity, thin stainless steel is only about one-third of that of ordinary low-carbon steel, and the degree of restriction is small. Therefore, once it is locally heated and cooled during the welding process The effect of the welding line will cause uneven stress and strain. The longitudinal shrinkage of the weld will produce a certain pressure on the outer edge of the stainless steel sheet. Once the pressure of the traditional welding machine is too large, it will cause the wave-like deformation of the workpiece, which not only affects the appearance, but also affects the appearance. In addition to the quality of the workpiece, there will also be problems of overburning and burning through. 

The emergence of fiber laser welding machine has solved this problem well. Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses into the material through heat conduction to melt the material. Then a specific molten pool is formed. High welding aspect ratio, small welding seam width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welding seam, no treatment or simple treatment after welding, high welding seam quality, no porosity, and precise control , The focused light spot is small, the positioning accuracy is high, and it is easy to realize automation. With many advantages, laser welding machines are gradually replacing the traditional thin plate welding market. 

The above is the analysis of the advantages of laser welding machine in the field of thin plate welding. Laser welding machines are widely used in dental denture processing, circuit board welding, splicing steel plate welding, sensor welding, and battery sealing cover welding.
