Battery Laser Welding Machine
The RS-SWF-80/150 80W & 150W fiber laser welding machine is catering to the demand for high-quality high-speed laser welding for lithium battery cells. It can weld a wide range of materials and can realize the welding between different materials. such as steel, aluminum, copper, nickel, etc
Features of Laser Welding for Lithium Battery
1. It can be used for spot welding, butt welding, overlap welding, seal welding, and wire filling welding.
2. high welding speed, small heat-affected zone, and the deformation are small.
3. The welding seam is smooth and beautiful, and no or only simple treatment is needed after welding
What is battery welding?
Welding is a very important manufacturing process from the manufacturing of lithium battery cells to the battery pack group. The conductivity, strength, air tightness, metal fatigue, and corrosion resistance of lithium batteries are typical battery welding quality evaluation standards.
Why laser welding?
The structure of the battery usually contains a variety of materials, such as steel, aluminum, copper, nickel, etc., which may be made into electrodes, wires, or casings; therefore, the welding process is required for the welding process, whether it is between one material or between various materials. The technological advantage of laser welding is that it can weld a wide range of materials, and can realize the welding between different materials.
Advantages of laser welding
The selection of welding methods and welding processes will directly affect the cost, quality, safety, and consistency of the battery. Among many welding methods, laser welding stands out with the following advantages: first, the laser welding has high energy density, small welding deformation, and small heat affected area, which can effectively improve the precision of the parts, and the weld is smooth and free of impurities, even and compact, and no additional grinding is needed; secondly, laser welding can be precisely controlled, the focus light point is small, and the positioning is a high precision, and it is easy to cooperate with the manipulator, In addition, laser welding thin plate or wire rod will not be affected by reflow as arc welding.
