Detailed Product Description: | "Shenzhou VIII" successful launch, and with the "Temple" of the successful docking, the Chinese space station around 2020, has taken a key step. China's aerospace technology once again achieved a major breakthrough, which, laser technology in aerospace applications denied. So, on the eighth Divine laser technology which may be used it? After the analysis, the following aspects may be using this technology: Precision Welding (a) emitting devices and electronic equipment inside the spacecraft that is most widely used technology of laser applications in the aerospace field, with respect to the laser beam welding, plasma beam and the traditional welding methods have their own unique advantages, such as high energy density, small heat-affected zone and deformation zone, welding of different materials can be combined with high flexibility, etc., plus sealing, suitable for special environment such as vacuum Under processing, laser welding and therefore are widely used, such as sensors, seals, tantalum capacitors in aerospace member. (B) the spacecraft shell and cutting special alloy components in the manufacture of aerospace equipment in the design of the housing only needs to repeatedly test, since the shell is made of special metal materials, high strength, high stiffness, high temperature, general cutting means is difficult to complete materials processing, laser cutting as an efficient means of processing and are widely used. Laser cutting technology is an out of the traditional mechanical cutting, heat treatment and cutting of the new cutting method, we can focus the energy into a tiny space, so as to obtain a high radiation power density (105 ~ 1015W / c m2), which has a higher cutting accuracy, lower surface roughness values, more flexible method of cutting and higher productivity and so on. In addition, the Shenzhou VIII spacecraft, the internal components are also extensive use of aluminum, titanium, high temperature alloys and other special alloys, the structure of complex shape, requiring precision forming, while the introduction of high-power laser cutting machine processing technology, energy improve the quality of processing, reduce tooling investment costs, shorten production cycle, especially for complex parts machining. The spare parts processing is used in high-power laser cutting machine, and now the localization of high-power laser cutting machine processing technology has been with the international advanced level. (C) Upon dicing film solar cells spacecraft successfully into space from the launch vehicle, solar panels started after the equivalent of a small power plant, by converting solar energy into electricity to provide energy for the electrical equipment on the spacecraft. Although the spacecraft with an emergency power supply, but the support time is limited, so mainly rely on the sun to provide power windsurfing. This time, the Shenzhou VIII spacecraft power windsurfing with a new film solar cells: the new three-junction gallium arsenide cells, originally from God to Shenzhou VI using a single crystal silicon solar cells, previously only 14.8% of the photoelectric conversion efficiency, and God eight and "Temple" are used in the conversion efficiency of 26.8% efficient triple junction gallium arsenide solar cells. Therefore, generation capacity increased by 50%. This battery is generally a germanium substrate (Ge), prior laminated epitaxial growth, the substrate is required scribing treatment. Quality substrate scribing directly affect battery performance. Laser scribing technique, especially short-wavelength laser such as green / UV laser, the processing of small heat-affected zone, superior quality scribing. Non-contact machining process produces a blade to avoid stress, can improve the grade rate of the substrate, while the battery performance has greatly improved, and therefore widely used in the manufacturing process of solar cell sheet. (Iv) aerospace parts marking military products, aerospace components require high-quality tracking, marking parts are commonly used laser marking to complete, such as aerospace sensors, aerospace tool. Laser Marking its contents can not be erased mark, acid corrosion, will not be dissolved organic solvent, it is widely used in aerospace and military products and other quality tracking. In addition, the spacecraft is also possible to use laser texturing metal plate material surface hardening. For building a space station rendezvous and docking, astronauts transport, supply materials, and even in space critical rescue, fully grasp the technology and facilitate boarding moon exoplanets. After completion of the rendezvous and docking mission, Shenzhou spacecraft will gradually form a cured state space shuttle manned spacecraft, Batch production. As China's aviation industry with impressive speed big step forward, laser applications in aerospace field, will be more extensive and in-depth.
