Laser technology has been upgraded again

2022-02-21

On April 24,1970, the Dong Fang Hong I of China`s first man-made satellite was launched, and when the familiar song of The East Is Red rang, all the witnesses were drenched in tears. The Chinese dream of flying has finally come true thanks to the unremitting efforts of generations of scientists looking up at the stars. Today, China`s SHENZHOU-12 spacecraft has been successfully launched, and China`s cause has made remarkable achievements, in addition to the efforts of researchers at the Down to Earth, many people do not know that modern laser technology is also playing a role in the field. Modern laser technology in the field of application is mainly in cutting, laser welding, laser drilling and other aspects. In the industry with laser cutting materials are: alloy, nickel alloy, chromium alloy, aluminum alloy, stainless steel, acid key, plastic and composite materials. In the manufacture of the equipment, the Shell is made of special metal material, which has high strength, high hardness and High temperature resistance. It is difficult to finish the material processing by common cutting means. Laser cutting is an efficient processing means, can Be used for laser cutting aircraft skin, honeycomb structure, frame, Wing Bin, tail avoid plate, helicopter main rotor, engine casing and Flame Tube, etc. . Laser cutting generally used continuous output laser, there are high repetition rate of carbon dioxide pulse laser. The depth-to-width ratio of laser cutting is high, for non-metal, the depth-to-width ratio can reach more than 100, the metal can reach about 20. Laser cutting speed is high, cutting Chin Alloy Sheet is 30 times of mechanical method, Cutting Steel Sheet is 20 times of mechanical method. 2 Jpg
