Laser welding machine is one of the important components of laser material processing. Laser welding is a precision welding technology that uses high-energy laser beams as heat sources. It mainly heats the surface of the workpiece through high-energy laser beams, and the heat diffuses from the material surface to the inside. By adjusting the parameters of the laser pulse, the corresponding material is melted, forming a specific molten pool.
The principle of laser welding machine can be divided into heat conduction welding and laser deep penetration welding. Laser welding uses laser energy to combine materials of different materials, thicknesses, or shapes to meet the material performance requirements of different situations. It can achieve equipment lightweight with the lightest weight, optimal structure, and optimal performance.
Stainless steel materials are widely used in the manufacturing of various finished products, and the welding of stainless steel sheets has become an important process in the production and manufacturing process. However, due to the inherent characteristics of thin plate stainless steel, welding also poses certain difficulties, which has become a welding challenge in the field of thin plate stainless steel.
Traditional welding machines have a great challenge in processing thin stainless steel plates. Due to its small thermal conductivity, which is only about one-third of that of ordinary low-carbon steel, and its low degree of constraint, once subjected to local heating and cooling during the welding process, uneven stress and strain will be formed. The longitudinal contraction of the weld seam generates certain pressure on the outer edge of the stainless steel plate, Once the pressure of traditional welding machines is too high, it will cause wavy deformation of the workpiece, which not only affects the aesthetics but also affects the quality of the workpiece. In addition, there will also be problems of over burning and burning through.
The emergence of fiber laser welding machine has effectively solved this problem. Laser welding machine is the use of high-energy laser pulses to locally heat materials in small areas. The energy radiated by the laser diffuses through the internal diffusion of the material through heat transfer, melting the material and forming a specific molten pool. High welding depth to width ratio, small weld seam 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 air holes, precise control, small focus point, high positioning accuracy, and easy automation. Laser welding machine are gradually replacing the traditional thin plate welding market with multiple advantages.
The above is an 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, battery sealing cover welding, and other aspects.
