Overview of Battery Laser Welding Equipment

Utilizing a fiber optic or diode laser, this machine promptly heats the current collector and contact plate, leading to their fusion.

This advanced procedure is completed in less than a second, thanks to rapid energy transmission.

The footprint required for a laser system is minimal, making it highly space-efficient.

Laser welding provides remarkable flexibility for adjustments in subsequent processes due to its non-contact nature.

Laser Welding Features for Battery Connections

Welding of Battery Tabs

The connection points, or tabs, are typically created from three different materials: copper, aluminum, and nickel. The battery's positive terminal usually consists of aluminum, while the negative terminal is made from nickel or nickel-plated copper. A crucial step in power battery production involves welding the battery poles and tabs together. For secondary batteries, an aluminum safety valve must also be welded in place. This welding must ensure a solid connection between the lug and the pole while producing aesthetically pleasing weld seams.

Electrical Connections

The process begins with connecting the cells through the contact tabs and current collectors. Following that, the joints' conductivity is verified using resistance measurements. The welding seams undergo optical inspection during the operation, facilitated by a high level of automation.

Explosion-Proof Valves

The explosion-proof valve on a battery features a thin-walled design integrated into the battery's sealing plate. If the internal pressure reaches beyond a predetermined limit, the valve ruptures to avert potential explosions. This component's intricate structure demands strict adherence to quality in the laser welding process. Continuous laser welding enables high-speed, quality welds while ensuring stability, efficiency, and yield consistency.

Pulse Welding Technology

Battery pole strips may consist of pure aluminum, nickel strips, aluminum-nickel composites, or a small amount of copper. Typically, pulse welding machines are used to weld these pole strips. The QCW quasi-continuous laser demonstrates excellent beam quality and produces small welding spots (under 1.5 mm) which confer distinct advantages.

Precision Advantage

Laser welding provides high levels of precision and accuracy, enabling complex and intricate welds with minimal heat-affected zones. This results in cleaner, more refined welds compared to conventional techniques.

Speed Efficiency

Characterized by its speed, laser welding can carry out tasks rapidly, significantly boosting productivity while shortening manufacturing lead times.

Reduction in Distortion

Laser welding minimizes distortion within the workpiece, leading to reduced material wastage and enhanced quality of the welded components.

Automated Processes

The compatibility of laser welding machines with automated manufacturing processes permits ongoing production with little human interaction, thus improving efficiency and lowering labor-related expenses.
