Although compared with traditional welding methods, laser welding machines are expensive, have a large one-time investment, and have high technical requirements. At present, their application in the industry is still relatively limited. However, significant features such as high production efficiency and easy to implement automatic control make It is very suitable for large-scale production lines and flexible manufacturing. Laser welding will become the development focus of the next green laser pointer industry. Because the laser beam has a small laser focal spot and high power density, it can weld some high melting point and high strength alloy materials.
And because the heat-affected zone of laser welding is small, the material deformation is small, and subsequent processing is not required. In the process of use, the laser beam is easy to guide and focus, realizing the transformation in all directions, and the laser welding has high production efficiency, stable and reliable processing quality, and good economic and social benefits. All kinds of advantages make more and more enterprises start to use laser welding machines instead of traditional welding. The traditional welding method takes a long time and has low efficiency, so in the mid-1980s, laser welding as a new technology received widespread attention in Europe, the United States, and Japan.
But to talk about the development of green laser pointers welding, it is also necessary to start from 2002. On October 25, 2002, China’s first professional commercial production line for laser tailored blanks was officially put into operation. It was introduced by Wuhan ThyssenKrupp Zhongren Laser Tailored Welding from Germany’s ThyssenKrupp Group TWB. Since then, Shanghai Baosteel Arcelor Laser Welding Co., Ltd. and FAW Baoyou Laser Welding Co., Ltd. have been put into production successively.
