Laser welding machine is a relatively mature industrial laser technology at present. Others including laser marking, laser scribing, laser drilling and laser fine-tuning also play a significant role in industrial production and manufacturing. The more common ones in life are YAG laser welding machines, optical fiber transmission laser welding machines, fiber laser welding machines, and nanosecond laser welding machines. How does the laser welding machine work? The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses to the inside of the material through heat conduction, and the material is melted to form a specific molten pool.
It is a new type of welding method, mainly aimed at the welding of thin-walled materials and precision parts, which can realize spot welding, butt welding, lap welding, sealing welding, etc., with high depth-to-width ratio, small weld width, and small heat-affected zone. The deformation is small, the welding speed is fast, the weld seam is smooth and beautiful, no treatment is required or only simple treatment is required after welding, the weld seam quality is high, there is no air hole, it can be precisely controlled, the focusing light spot is small, the positioning accuracy is high, and it is easy to realize automation. For laser users, the benefits of laser welding machines are obvious, such as laser sources capable of multitasking and compact, often air-cooled, integrated forms that allow for seamless integration. Conventional wisdom has it that welding and joining require millisecond-long pulses with high pulse energies, but this is clearly not the case! Little is known about the material joining capabilities of this type of laser, but they are excellent at joining ultra-thin materials.
During the welding process of the specific workpiece, the automatic laser welding machine can change the output waveform of the laser energy according to the shape and material of the work, which can greatly improve the welding quality. Even some traditional laser welding problems can be obtained by changing the output waveform of the laser. solve. Across the globe, industries such as consumer electronics, energy storage and medical devices need to pack more functionality into increasingly smaller and denser packages. Therefore, there is a greater need for efficient manufacturing techniques to help these products become a reality.
