Laser welding technology has unlimited development potential

　　In the application of laser material processing technology, there is one aspect that is very important, that is, laser welding, which is often referred to as laser welding machine and laser welding machine. To say the difference, as long as it is divided according to the working mode, it can be divided into laser mold welding machine, automatic, laser spot welding machine, and optical fiber transmission. The working principle of optical welding is to use high-energy laser pulses to locally heat the material in the smile area, and diffuse the energy of the laser radiation to the inside through thermal conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding.

　　 was mainly used for welding thin-walled materials and low-speed welding in the 1970s. The welding process is thermally conductive, that is, the surface of the workpiece is heated by laser radiation, and the surface heat is diffused into the interior through heat conduction. By controlling the width of the laser pulse, Parameters such as energy, peak power and repetition frequency make the workpiece melt and form a specific molten pool. Because of its unique advantages, it has been successfully applied to precision welding of micro and small parts.

The emergence of 　　 high-power CO2 and high-power YAG lasers has opened up new areas. Deep penetration welding based on the pinhole effect has been obtained, and it has been widely used in machinery, automobiles, steel and other industrial fields.

　　 At present, the world's industrial field is developing towards low energy consumption and short process. Laser welding technology has many advantages that traditional welding methods can’t match. Countries all over the world have paid more attention to the development of manufacturing. degree. However, compared with foreign countries, China's laser technology has not been applied and promoted, and it has not yet played its due role. The reason is firstly the high cost and high investment of the laser manufacturing system; in order to popularize the application of laser welding technology more widely and make up for the problem of high investment, it is necessary to fully understand the key factors affecting the application of laser manufacturing technology and comprehensively consider Factors such as the needs of ships and the input of laser processing systems, control costs, find the best processing conditions, and methods to improve processing efficiency, and finally form a new generation of laser manufacturing industry chain in China.

　　In industrial manufacturing, technology is very unique. The processing and application characteristics of the industrial field and the characteristics of the laser manufacturing system are closely related. Nowadays, the important material for the manufacture of transportation machinery is aluminum alloy. The all-aluminum structure ship shows a good development prospect, and with advanced laser manufacturing technology, it shows unlimited development potential.
