With the "Temple" launch, indicates that China's space technology to a new level, while laser technology as the most advanced in the world today, one manufacturing process technology, its use in the aerospace industry, for our country the rapid development of the aerospace industry plays an important role in promoting. Whether it is "Temple" target aircraft, or before the "Shenzhou VII" spacecraft, "Moon" plan, "large aircraft" program, manned space projects, it is widely used in laser technology. The following describes the application of the aerospace industry in several laser processing technology: (a) laser welding technology: It is the most widely used technique of laser applications in the aerospace field, because the laser welding with respect to the electron beam, plasma beam and traditional welding The method has its own unique advantages: ⑴ high energy density. After the high-power laser beam a focused, focal spot diameter is small, so the high power density of up to 105 ~ 108W / cm2, compared arc welding (5 × 102 ~ 104W / cm2) several orders of magnitude higher, can be welded high hardness, high brittleness and high melting point, high-strength materials. ⑵. Heat affected zone and the deformation zone is very small. Laser welding high heating and cooling rate, the crystallization rate several times higher than the general welding and heat affected zone is very small, small material deformation, without subsequent treatment processes. ⑶. Combination welding of different materials. It can be quite different or the same kinds of dissimilar metal materials high melting point, high thermal conductivity, physical properties of welding. ⑷. Laser welding system with high flexibility. Welding systems and CAD / CAM or robot coalition can be formed multifunction laser processing systems, welding speed, high efficiency, easy to automate. Before the 1970s, the absence of high-power CW laser device, so the focus of the study is small precision parts welding, or lap joints made by a single weld seam. And now, as the laser power increases, and now more than ten millimeters thick steel plate welding is relatively easy. In addition, due to the small heat affected laser welding, sealing, and suitable for processing under vacuum and other special circumstances, it has been widely used in aerospace devices. At present the latest applications of laser welding result is to replace the traditional rivets aluminum laser welding technology for the manufacture of aircraft fuselage aircraft so as to reduce body weight by nearly 20%, increase the strength of nearly 20%, and now the German aerospace company MBB, Airbus We have applied this technique.
