In recent years, as a kind of high quality, high precision, low deformation, high efficiency and high speed welding equipment, laser welding machine is becoming an important tool for metal material processing and manufacturing, and is more and more widely used in automobile manufacturing and other fields. Laser welding is to radiate high intensity laser beam to the metal surface. Through the interaction between laser and metal, the metal absorbs the laser and converts it into heat energy so that the metal melts and then cools and crystallizes to form welding.
This welding method is not only highly automated and fast, but also more convenient for welding any complex shape. Although compared with the traditional welding methods, laser welding machine is expensive, one-time investment is large, technical requirements are also very high, the application in China's industry is still relatively limited, but high production efficiency and easy to achieve automatic control and other significant characteristics make it very suitable for large-scale production lines and flexible manufacturing.
Because the laser beam laser focus spot is small, the power density is high, can weld some high melting point, high strength alloy material. Moreover, because of the small heat affected area of laser welding and the small deformation of materials, there is no need for subsequent processing. In the process of use, laser beam easy to guide, focus, to achieve the direction of change, and laser welding production efficiency is high, stable and reliable processing quality, good economic and social benefits. Various advantages make more and more enterprises begin to use laser welding machine to replace the traditional welding.
Laser welding is different from laser marking and cutting. Its biggest characteristic is customization. Laser marking and laser cutting can produce large-scale and mass-produced products, but welding is difficult to do because the demand of each customer varies greatly, making it difficult for laser welding to produce large quantities. However, with the arrival of the Internet and personalized demand, small and medium-sized system integrators and automation companies show geometric growth, followed by more and more application demand for laser welding, this situation will change substantially.
