With the continuous development of science and technology, many industrial technologies have special requirements for materials. The materials manufactured by casting methods can no longer meet the needs. Therefore, it is particularly necessary to use powder metallurgy methods to produce some materials used in modern industries. With the increasing development of powder metallurgy materials, the connection problem between them and other parts has become increasingly prominent. Brazing and projection welding have always been the most commonly used methods for connecting powder metallurgy materials. However, due to their low bonding strength and wide heat affected zone, they are particularly unsuitable for high-temperature and high-strength requirements situations, which limits the application of powder metallurgy materials.
Laser welding machine technology has entered the field of powder metallurgy material processing with its unique advantages. Compared with traditional welding methods, laser welding has a large depth-to-width ratio, narrow weld seam, and high weld joint strength; the heat affected zone is small, having no impact on the surrounding structure, and the welding deformation is small; it can achieve automatic welding process, with high production efficiency, and thus has developed rapidly in the field of powder metallurgy material processing.
What are the advantages of using laser welding machines in the powder metallurgy industry?
1. Humanized design, with LCD screen display and centralized button operation, making it simpler.
2. The precision laser welding machine has high-quality weld seams that are smooth, beautiful, and free of pores. The post-weld material toughness is at least equivalent to the base material.
3. The precision laser welding machine can perform spot welding, butt welding, lap welding, and sealing welding on thin-walled materials and precision parts.
4. The laser power of the precision laser welding machine is large, the weld seams have a high aspect ratio, the heat affected zone is small, the deformation is small, and the welding speed is fast.
5. The current waveform of the precision laser welding machine can be adjusted arbitrarily. Different waveforms can be set according to the different welding materials to match the welding parameters and requirements, achieving the best welding effect.
6. The four-dimensional ball screw worktable of the precision laser welding machine adopts imported servo control system. An optional rotating worktable can be selected, enabling automatic welding such as spot welding, linear welding, and circular welding. It has a wide range of applications, high precision, and fast speed.
Laser welding machines enter the powder metallurgy material processing field with their unique advantages, opening up new prospects for the application of powder metallurgy materials. For example, when using the commonly used brazing method to weld diamonds in powder metallurgy materials, due to the low bonding strength and wide heat affected zone, especially unable to adapt to high temperatures and high strength requirements, resulting in the melting and shedding of the filler metal, laser welding machines are used to improve the welding strength and high-temperature resistance.
