4000W Automatic Cantilever Fiber Laser Welding Machine For Battery Pack Manufacturing

The ACEY-CLW4000W Cantilever Galvo Laser Welding Machine is specifically designed for lithium battery pack welding applications, including aluminum busbars, nickel connecting sheets, battery electrodes, and copper-aluminum composite components.

This advanced system integrates a 4000W fiber laser source with a three-axis coordinated cantilever structure and high-speed galvanometer scanning system. The large working range provides flexible access to various welding positions, making it suitable for battery modules and packs of different sizes.

With programmable welding paths and adjustable laser energy waveforms, the machine can perform welding points, straight lines, curves, and customized patterns. Stable and precise welding reduces connection resistance, improving the electrical performance and reliability of assembled battery packs. For pouch battery applications, the standard welding head can be replaced with a dedicated pouch battery welding head.

The ACEY-CLW4000W is primarily intended for aluminum, nickel, copper-aluminum composite materials and selected lithium battery connection components.

• Three-Axis Cantilever Structure - The coordinated three-axis cantilever design offers a broad working range and flexible positioning, allowing the welding head to access various areas of large battery packs without frequent workpiece repositioning.
• High-Speed Galvo Welding - The galvanometer scanning system directs the laser beam at high speed, boosting welding efficiency compared with conventional point-by-point mechanical movement methods.
• Programmable Welding Patterns - The control software supports welding in point, line, curve, circle, and custom patterns, enabling the machine to handle different battery layouts and complex connection configurations.
• Adjustable Energy Waveform - Laser output power and energy waveforms can be tailored to the material, thickness, and joint structure, helping achieve consistent penetration and improved welding quality.
• Graphical Control Software - The integrated graphics processing software simplifies welding path editing and parameter configuration, reducing the complexity involved in switching battery models or welding patterns.
• Stable Continuous Operation - A reliable control system, high-quality optical components, and a water-cooling system support extended operating periods while maintaining stable laser output and consistent processing performance.
• Welding and Marking Functions - In addition to battery connection welding, the machine also supports laser marking and pattern processing. Stainless steel nameplates can be marked; however, stainless steel welding is not an application specified for this model.
• Reinforced Machine Body - The main enclosure is thickened and reinforced to ensure high structural rigidity. It can also serve as a stable working platform, helping improve space utilization in the production area.
