Laser welding. Laser welding of high strength, heat distortion, and good sealing can be welded between the size and nature, as well as a high melting point materials (eg ceramics) and ease of oxidation. Laser welding of the pacemaker, good sealing, long life and small size. The development trend of the laser. Laser processing for re-manufacturing and applied to other manufacturing, irreplaceable advantages, and better than other processing techniques. Laser processing for re-manufacturing is the transformation hardening to the laser surface alloying and laser cladding by laser alloy coating to the composite coating and ceramic coating, which makes the laser surface processing technology to become a re-manufactured important tool. The green laser pointer is usually used in the theater, night pub, entertainment hall, outdoor advertisement and land mark and so on.
It is mainly 5KW ~ 10KWCO2 high-power laser systems. Compared with the laser processing system, the gap of China's laser processing systems is very large, only about 4 percent of global sales. Mainly as follows: high-end laser processing system little or nothing; the main laser, but off; fine laser processing equipment gap; production and processing enterprises in these areas, China is gathering strength, steadily into the domestic application of the market has ample room. Predict the next 2-3 years, China's laser processing sales will rise by 3.5 billion yuan in 2008 to double, which means that will reach 70 billion yuan output value. Various types of domestic manufacturing industry has accepted the laser processing technology. The emitter ofgreen laser pointer has the exclusive address code when it comes out of the factory.
It will enable their products to increase the technical content, speed up product upgrading, and to adapt to the 21st century high-tech industrialization, high-performance light to meet the needs of macro-and micro-manufacturing, research and development is imperative. Extreme ultraviolet ultrashort pulse, ultra-high-power, high beam quality characteristics of the laser is currently being actively developed, in particular, is able to adapt to technical requirements of micro-fabrication laser light source is more closely watched, and has formed an international competition. Made a detailed introduction to the principle of laser processing, origin, application, development trends, and to analyze the combination of laser processing and other common problems, will certainly help the understanding of laser processing. And recently, green laser pointer is also used in the store advertisement.
Laser cutting machine is the use of focused high power density laser beam workpiece, so that the irradiated material rapidly melting, vaporization, ablation, or to achieve ignition, with the beam coaxial high-speed airflow to blow the molten material in order to achieve the workpiece cut. Laser cutting belong to one of the thermal cutting. Laser cutting machine principle is shown below. Laser cutting of the development status. Laser Institute of Hunan University in 1994 developed the first domestic analysis of shelf fold quasi closure off cutting and welding laser, and obtained the national invention patent. Foreign products 1/2 the price of each device. green laser pointer can automatically generate various types of laser beams, laser pictures, and laser letters and so on to the music rhythm.
In March 2003, CNC laser tube processing equipment developed by the CAS Changchun Institute of Optics and Fine Mechanics and Physics, changing the situation of China's oil industry relies on imported equipment processing pipe. This indicates that China manufacturing advanced equipment has reached the international advanced level. Jinan Foundry NC Machinery Company in the development of manufacturing made the first of the LC2-18 * 30 type switching bilateral table-driven precision CNC laser cutting machine. The breakthrough in the design of two key technologies, first, to solve the axis of bilateral drive two electrodes synchronization, the second is to solve the synchronization problem of the eight cylinders of the lifting table. In September 2004, the laborers technology is the successful launch of the first localization of high-performance laser cutting machine. green laser pointer can create entertainment or romantic or mysterious atmosphere on the stage or in the ballroom, pub, KTV and family party.
