Beautiful Life

For burning laser pointer welding of diamond saw blade, the need for appearance, microstructure and welding strength and other parameters of the test. The appearance of the main detection of the existence of welding macroscopical defects such as hole cracks, undercuts and not penetration, etc., usually need to be 100% of the detection, significant organizational detection of the main parts of the chemical parts of the inspection, significant changes in the structure and phase structure, The results show that the fine chemical composition of the molten zone has a gradient diffusion, and the transition layer hardness is lower than that of the matrix, which is higher than that of the tip. The welding strength test mainly tests the tensile strength, bending strength, impact toughness and residual stress of the weldment. It is usually necessary to carry out 100% welding strength test, and the residual stress and distribution after welding seriously affect the service life of the diamond saw blade.

At present, there are still some problems in laser welding of diamond saw blade technology, we need to carry out further research, to carry out special laser welding diamond saw carcass or transition layer material formula research, to carry out new ultra-fine or nano-alloy powder research, The research on the mechanism of 3000mw laser pointer welding of diamond saw blades, especially the research of temperature field, flow field, mass field and stress field of laser welding diamond saw blade and the on-line quality monitoring technology of laser welding diamond saw blade process are carried out. In fact, only a comprehensive understanding of the mechanism of laser welding diamond saw blade, it may be developed accordingly the new online quality monitoring technology; only master the theory of pre-alloy powder, it is possible to develop a new ultra-fine or nano-alloy powder and Better use of new ultra-fine or nano-pre-alloy powder to develop a dedicated diamond saw blade.

For large gantry laser cutting machine, to achieve high-speed, high-precision linear cutting, large arc cutting is a common technology, but to achieve a small round cut can only reduce the speed, laser cutting machine efficiency doubled. At the same time to achieve high-precision small round cutting, for large gantry cutting machine must improve the overall rigidity and dynamic performance of the machine. In order to meet the needs of special customers, a laser R & D and production of 2.5G super dynamic performance GHF-4020 high-speed high power laser pointer cutting machine. Up to 400 per minute cutting high-precision small round of the magic speed, compared to the traditional laser cutting machine can only cut 100 rounds per minute, the efficiency increased by 4 times. Its performance has been quite stable, cutting quality, cutting efficiency completely exceeded expectations.

Laser is the best way to optimize most of the existing processing technology at home and abroad. At home and abroad, after two well-known cutting and welding processes such as cutting, welding, surface treatment and cladding, The craft has done a breakdown. For example, for cutting, subdivided into melting-type cutting, vaporization-type cutting, and the melting of the cutting section of the roughness of the cutting, the vertical degree of more refined requirements, etc., which the laser and other ancillary manufacturers have put forward a new Of the high demand, so the industry is even with the integration of one of the key elements.

In the field of fiber laser, fiber lasers will further enhance the application coverage. There is also a saying that the structure of fiber lasers is to optimize the quality of direct semiconductor 1000mw green laser beam cost-effective program, so these two lasers do not conflict, but complement each other. The future In the field of metal processing, fiber laser vitality will be very strong, which may become a new trend. In terms of laser, different wavelengths, different power, different control methods of technology is the core, need a long time to layout. At this core, it is imperative to optimize the structure and technology of existing wavelengths of lasers to meet their potential needs in the current market. Such as higher average and peak power, shorter pulse width and so on.

Quasi-continuous single-mode / multi-mode laser products is characterized by single-mode or multi-mode output, respectively, adapted to cutting and welding, the main application areas are galvanometer spot welding, fine cutting. The direct semiconductor multi-mode continuous 5000mw green laser products are based on the company's more mature pump source introduced, the core feature is a certain anti-high anti-ability, mainly used in soldering, brazing, cladding, sintering, surface treatment and other fields The The principle and structure of different lasers have their own advantages and limitations. Fiber laser has been highly recognized in the field of metal processing because of its high efficiency of electro-optical conversion, flexible transmission optical path, maintenance-free and low cost. On the hot spot.
