Advantageous Application Of Laser Welding Machine in Battery Manufacturing Industry
Laser welding machines have always been an indispensable process in the lithium battery manufacturing process, and various materials are widely used in laser welding, such as stainless steel casings, aluminum casings, polymers, etc. The high speed held by laser welding machines is unmatched by other welding technologies. With the continuous development of the industry, higher requirements are placed on the efficiency and quality of laser welding. Fiber lasers promote high-speed welding, which can achieve low heat at the welding place. Input and high solidification rate to effectively control solidification defects in mixed metal welding.
The structure of the battery usually includes various materials such as steel, aluminum, copper, nickel, etc. These metals may become wires and casings, etc. Therefore, whether it is welding between one material or between multiple materials, all welding technology is proposed. Very demanding. The technical advantage of the laser welding machine is that it can weld a wide variety of materials and can realize welding between different materials.
Laser welding has high energy density, small welding deformation, and small heat-affected zone, which can effectively improve the accuracy of the workpiece. The welding seam is smooth without impurities, uniform and dense, and no additional grinding work is required; secondly, the laser welding machine can be accurately controlled and focused on the spot. Small size, high-precision positioning, and easy automation with robotic arms, improving welding efficiency, reducing man-hours, and reducing costs; in addition, when laser welding thin plates or thin-diameter wires, it is not as easy to be troubled by melting back as arc welding.
Lithium battery manufacturing equipment is generally divided into three types: front-end equipment, mid-end equipment, and back-end equipment. The equipment precision and automation level will directly affect the production efficiency and consistency of products. As an alternative to traditional welding technology, laser welding machining technology has been widely used in lithium battery manufacturing equipment.
