Advantages of laser welding square aluminum shell battery:

1. First, laser welding has higher energy density, lower welding density and less heat affected zone, which can effectively improve the accuracy of the workpiece, smooth, uniform and dense impurities in the weld, without additional polishing;

2. Second, accurate laser welding, precise control of the spot, accurate positioning, improve the welding efficiency, shorten the working time, reduce the production cost;

3. In addition, for thin sheet or fine diameter materials, laser welding, there will be no melting phenomenon;

4. The construction of the final unit typically consists of various materials, such as steel, aluminum, copper, nickel, etc., which can be made into electrodes, wires, or enclosures; Therefore, whether it is a material or several materials of the material, all need high welding technology, the advantage of laser welding technology is that you can use a variety of materials for welding, so as to achieve different welding effects.
