After the new energy vehicle enters the "rapid development" stage, it can be expected that the advanced manufacturing technology represented by laser technology will not only promote the upgrade of the automobile industry, but also drive the development of the entire industry. Especially the important application of laser welding technology in the automobile industry, its application field will be more extensive.

Laser welding uses a laser beam with a high energy density to heat a workpiece so that its operating temperature rises rapidly, and then fuses it together to form a permanent connection. Compared with other welding methods, laser welding technology has the advantages of melting depth, fast, small deformation, low requirements on the welding environment, high power density, not affected by magnetic field, not limited by conductive materials, no need for vacuum, no need for X-ray welding and so on. It has been widely used in high-precision machining. However, compared with other welding technology, laser automatic welding complete sets of equipment cost is high, high requirements for automation equipment, manual operation is difficult. At present, laser welding technology is more and more widely used in automobile, power battery and so on.

Laser welding technology is fast, easy to realize remote control, automation and other characteristics, widely used in the automobile, new energy lithium battery and other industries, especially in recent years, with the development of new energy vehicles, the demand for laser welding equipment is increasing. The main application technologies in the automobile industry are: laser of unequal thickness plate, laser welding of body assembly and parts, laser welding of automobile parts, and in the power battery, the use of explosion-proof valve sealing welding, pole lug, soft connection, battery housing sealing, module and PACK welding and other processes.

With the reshaping of the global manufacturing structure, the government has issued "Made in China 2025", which defines the upgrading direction of China's manufacturing industry and focuses on industrial production automation and informationization. The government has introduced a number of relevant policies and measures to actively guide the development of industrial automation. In 2015, China has become the largest sales of new energy vehicles. The lithium battery industry in new energy vehicles is developing rapidly, especially the automation of new energy vehicles is extremely high.

Xinde laser gantry galvanometer laser welding machine is a loose bead linkage high-precision working mode, can welding a large number of materials, high power collimation laser welding head, to achieve large gap welding can meet the new energy lithium battery nickel, pole lug, pole, copper and aluminum connecting sheet, confluence connecting sheet, square shell and polymer to nickel power battery pack laser welding, with laser welding spot fine, High precision, high degree of automation, can be welded various types of lithium battery pack welding requirements.
