Advantages of laser welding machine in powder metallurgy materials

With the continuous development of science and technology, many industrial technologies have special requirements for materials, and materials manufactured by smelting and casting methods can no longer meet the needs. Therefore, it is particularly necessary to use powder metallurgy to prepare some materials used in modern industry. With the increasing development of powder metallurgy materials, the problem of its connection with other parts is becoming more and more prominent. Brazing and projection welding have always been the most commonly used methods for joining powder metallurgy materials, but due to their low bonding strength and large heat-affected zone, they are not particularly suitable. The application of powder metallurgy materials in high temperature applications is limited and requires high strength.

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 the characteristics of large depth-to-width ratio, narrow weld seam, and high weld joint strength; the heat-affected zone is small, has no effect on the surrounding tissue, and the welding deformation is small; the welding process can be automated and the production efficiency is high. Therefore, it has developed rapidly in the field of powder metallurgy material processing.

What are the advantages of laser welding machines in the powder metallurgy industry?
1. Humanized design, LCD screen display, centralized button operation is easier.

2. The precision laser welding machine has high-quality weld seam, smooth and beautiful, no pores, and the toughness of the material after welding is at least equivalent to that of the base metal

3. The precision laser welding machine can realize spot welding, butt welding, lap welding and sealing welding of thin-walled materials and precision parts.

4. The precision laser welding machine has high laser power, high weld aspect ratio, small heat-affected zone, small deformation and fast welding speed.

5. The current waveform of the precision laser welding machine can be adjusted arbitrarily, and different waveforms can be set according to different welding materials to match the welding parameters and welding requirements to achieve the best welding effect.

6. The four-dimensional ball screw table of the precision laser welding machine adopts an imported servo control system, and a rotary table is optional, which can realize automatic welding such as spot welding, wire welding, and ring welding. Wide application range, high precision and fast speed.

With its unique advantages, laser welding machines have entered the field of powder metallurgy material processing, opening up new prospects for the application of powder metallurgy materials. For example, the brazing method commonly used in the joining of powder metallurgy materials is used to weld diamond. In particular, the area width cannot meet the high-temperature and high-strength requirements, causing the solder to melt and fall off. Adopt laser welding machine to improve welding strength and high temperature resistance.
