Laser Galvo Welding Machine

When welding thinner materials, such as metal sheets and nickel sheets for lithium battery tabs, traditional laser welding can produce significant thermal effects, leading to structural deformation or damage. In these cases, using a galvanometer laser welder often results in better welding results due to its shorter processing time. The operating principle of a galvanometer laser welder is similar to that of a Laser Marking Machine. A scanning galvanometer rapidly deflects the laser beam, melting smaller volumes of welding materials like tin in a very short time, resulting in finer welds. To maintain laser energy density, a focusing field lens (F-Theta lens) with a smaller focal length is typically required. Therefore, a specialized motion control system is often used to control the servo motor movement module to expand the available scanning welding range. Rotating or tilting fixtures can also be used to automate the welding of special shapes such as cones. For example, when welding individual cells and tabs for energy storage or power lithium battery packs, the efficiency of this machine is more than twice that of a laser welder, and the difference is even greater when welding entire battery packs. Although this machine itself lacks many automation features, it can be integrated into automated production lines and collaborate with MES, PLC, and other systems for automated welding.
