What is battery module laser welding?

Battery module laser welding is a technology that uses the thermal effect of a laser beam to weld various components in the battery module.

1. Working principle of laser welding of Huiyao laser battery module

Laser welding uses an optical system to focus the laser beam on a small workpiece area and utilizes its excellent directivity and high power density for processing. In a very short period of time, the laser beam causes the workpiece to form a heat source area with highly concentrated energy, thereby melting the workpiece and forming strong welding points and welds to complete the welding task.

2. Main forms of laser welding of Huiyao laser battery module
Laser welding is mainly divided into several forms such as heat conduction welding, deep penetration welding, penetration welding and seam welding. Each form has its specific application scenarios and advantages. Huiyao Laser battery module welding equipment mainly uses penetration welding to firmly combine the battery with the CCS integrated busbar.

3. The significant advantages of Huiyao laser battery module welding equipment

Uniform heat distribution: Huiyao Laser generally uses a 4+2 ring spot laser. The ring spot design makes the heat more evenly distributed during the welding process, effectively reducing thermal stress concentration and deformation, and reducing the occurrence of welding defects, such as pores and cracks. wait.

High-precision welding: Huiyao Laser's 4+2 annular spot laser welding technology can ensure the accuracy of each solder joint through fine spot control and energy distribution, reaching micron-level welding accuracy. This improves the overall accuracy of module welding and ensures high quality welds.

High-efficiency welding: Huiyao Laser optimizes the spot design and the 4+2 annular spot laser welding technology can cover a larger welding area and weld multiple points at the same time, significantly improving the welding efficiency.

Environmental protection and energy saving: During the welding process, Huiyao Laser's 4+2 annular spot laser welding technology does not produce waste gas, waste water and other harmful substances, which is conducive to protecting the environment and the health of employees. At the same time, the efficient welding process also reduces energy consumption and production costs.

Fast welding speed: Huiyao Laser battery module laser welding equipment is fast and can complete a large number of welding tasks in a short time, improving production efficiency.

Automated production: Huiyao Laser's battery module welding equipment is integrated with the automation system to realize an automated battery module welding production line, reducing manual intervention and further improving production efficiency.

To sum up, battery module laser welding is an efficient, precise and reliable connection technology and has broad application prospects in electric vehicles, energy storage equipment and other fields.
