With the continuous development of science and technology, many industrial technology on the special requirements of the material, the application of smelting and casting method of manufacturing materials has been unable to meet the needs, so the use of powder metallurgy method to produce a part of the modern industrial application of the material is particularly necessary. With the increasing development of powder metallurgy materials, it is increasingly prominent with other parts of the connection problem, brazing and convex welding has been the most commonly used method of powder metallurgy materials connection, but due to the combination of low strength, wide heat-affected zone, in particular, can not be suitable for high temperatures and high strength requirements of the occasions, so that the powder metallurgy materials application is limited.
Laser welding machine technology enters the field of powder metallurgy material processing with its unique advantages. Compared with the traditional welding methods, laser welding depth and width ratio is large, narrow weld, weld bond strength is high; heat affected zone is small, no effect on the surrounding organization, welding deformation is small; can realize the welding process automation, high productivity, and thus the development of powder metallurgy materials processing field faster.
Laser welding machine in the powder metallurgy industry application what are the advantages?
1, ergonomic design, LCD screen display, centralized keypad operation is simpler.
2, precision laser welding machine weld quality is high, flat and beautiful, no porosity, after welding the material toughness at least equivalent to the parent material
3, precision laser welding machine can be thin-walled materials, precision parts to achieve spot welding, butt welding, stack welding, sealing welding.
4, precision laser welding machine laser power, the weld has a high depth-to-width ratio, small heat-affected area, small deformation, welding speed.
5, precision laser welding machine’s current waveform arbitrary adjustment, according to the different welding material can be set up different waveforms, so that the welding parameters and welding requirements to match, in order to achieve the best welding effect.
6, Precision laser welding machine’s four-dimensional ball screw table, using imported servo control system, optional rotary table, can realize spot welding, linear welding, circumferential welding and other automatic welding, applicable to a wide range of high precision, high speed.
Laser welding machine with its unique advantages into the powder metallurgy materials processing field, for the application of powder metallurgy materials opened up new prospects, such as the use of powder metallurgy materials connected to the commonly used brazing method of welding diamond, due to the combination of low strength, wide heat-affected zone, in particular, can not adapt to high temperatures and strength requirements caused by high brazing material melting off, the use of laser welding machine in order to improve the welding strength as well as high-temperature resistant properties.
