Manufacture of laser is the laser as a source of energy, using the processing method of the photon energy of this new type of energy, through the optical fiber or the mirror group with very high speed implementation of light transmission, thus completing the processing tasks in the process. Laser manufacturing has a series of traditional manufacturing methods do not have the advantages, such as fast processing speed, high efficiency, low noise, in the air transmission, easy to realize automation, and with the continuous improvement of industrial development and the people to the laser technology level of understanding, laser in transport machinery manufacturing process accounts for the proportion of in a certain extent, reflects the level of manufacturing.
In the manufacture of ships, aircraft, vehicle and vehicle transport machinery, plate structure connection until now still mainly use the riveting process. This is due to the traditional welding methods, such as flame, arc, plasma arc heat source is divergent, a lower energy density, the welding speed is low, large amount of heat input, resulting in welding joint performance is poor. Different from the traditional welding heat source, the laser has excellent transmission and focusing properties, after the focus mirror group, the energy concentration can be highly concentrated. Therefore, laser welding can use the least energy function in the region of the smallest, greatly shorten the time, greatly improving the speed of processing, microstructure of the extremely small, near the weld heat affected small, welding deformation of the structure also minimum guarantee good performance of welded joints.
In the automobile industry as an example, from the development and fabrication of prototype parts to the body assembly, omnipresent laser. In the prototype development and small batch production, highly flexible 3D laser cutting is replaced a lot of punching and trimming die, not only saves a lot of mold, also the development cycle of new models is greatly shortened. In the auto parts maker, a variety of automotive gearbox laser welding to replace the traditional spline connection, electron beam welding, greatly improves the production efficiency and the transmission of the overall quality and performance, which can reduce the manufacturing cost of gear transmission, multiple choice, material saving, reduction of process; according to the different parts of the body bearing and the use of the request, using laser welding of different material, different thickness and different surface blank plate welded together and a pressing body parts manufacturing, body parts by laser thickness plate spell combination plate connected, significantly reduced the body weight, to replace the traditional welding way. In the body assembly, laser welding and brazing to replace the traditional resistance spot welding process. Due to the unparalleled advantages of laser manufacturing technology in Europe, almost all of the automotive manufacturing plant in the development and production of automotive without exception, without exception, a large number of laser processing. In fact, the breadth and depth of the application of laser manufacturing technology in automobile manufacturing has become an important symbol of the advanced nature of the automotive industry.
The laser manufacture is efficiency the highest process, most short, overall highest sealing, strength is the overall and spare parts from sign), save the most high alloy materials, light, save energy manufacturing.
