The application of laser welding technology needs to rely on high energy density laser beam, as a heat source, which belongs to a high precision and high welding efficiency welding method. Compared with the traditional commonly used welding technology, the application advantages of laser welding technology in new energy vehicles are mainly shown in the following aspects:
First, the maximum reduction of heat intake will also reduce the scope of the heat-affected area, thereby minimizing the incidence of adverse effects caused by heat conduction.
Second, electrodes are not needed in the process of applying laser welding technology, so there is no need to consider the damage of the electrodes themselves or the pollution problems brought by them. Because the mechanism welding is different from the general frontal contact welding method, it can also reduce the loss and deformation of the machine tools.
Third, the laser beam in focus, on time has the advantage, will be guided by chemical instruments, in the process of specific welding only need to be placed in a more appropriate distance from the workpiece. At the same time, in the process of guidance, it only needs to be carried out between obstacles or between machines around the workpiece, and it will be less restricted by space.
Fourth, in a relatively closed space, that is, in the internal gas environment or vacuum environment, the laser beam can be realized in a small range of aggregation, so it can realize the welding of a small range of parts. Laser welding can weld a wide range of materials, even can realize the welding of different kinds of heterogeneous materials.
Fifth, in the process of laser welding easy to become high-speed welding, can achieve computer or digital control. If the welding is some fine wire material, not like the use of arc welding is affected by melting, also will not be affected by the magnetic field, can be more accurate alignment in the process of welding parts to be welded.
Sixth, it can realize the welding of two kinds of materials with different physical properties, such as two kinds of metal materials with different resistances. Seventh, in the actual welding process does not need to use X-ray protection, and does not need a vacuum environment. Eighth, if the laser welding process is used in the perforated welding mode, the depth to width ratio of the pass can be more than 12:1.
Seventh, the laser beam can be delivered to different workstations at the same time by switching devices.
The use of laser welding in the manufacturing process of new energy vehicles can significantly improve its social and economic benefits, but also improve the quality of the welding interface, so that its stability is significantly improved, reduce the accident caused by joint problems and accident losses, from another level will also reduce the cost. In addition, the application of laser welding technology in the manufacturing of new energy vehicles will also solve the problems of environmental pollution and electromagnetic radiation existing in the traditional welding technology, with significant social benefits.
