What is the welding process of Huiyao laser battery module?

The battery module welding process is a key link in the battery PACK process. It uses advanced welding technology and equipment to ensure a strong and reliable connection between cells while reducing internal resistance and heat loss. Welding quality is directly related to the performance and safety of the battery module, so various parameters and quality standards during the welding process must be strictly controlled.

1. Welding method of Huiyao laser battery module

Laser welding:

Principle: An efficient and precise welding method that uses high energy density laser beam as a heat source. Laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through thermal conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool.

Features: high welding efficiency, easy to realize automated production; fast welding speed, large depth, small deformation, and high precision; small deformation of the workpiece, more stable performance changes, and higher welding quality. In addition, it also has the advantages of low welding material loss, high degree of automation, and stable performance.

2. Selection of Huiyao Laser Battery Module Welding Laser

When choosing a battery module welding laser, Huiyao Laser favors annular spot 4+2 power lasers, mainly based on the following key reasons:

1. Welding quality optimization:

The annular spot design can provide more uniform and wider heat distribution, which helps to achieve more uniform heating during the welding process and reduce the temperature gradient in the welding area, thereby reducing welding stress and deformation risk.

The 4+2 power configuration means that the laser has higher energy output and more flexible power adjustment capabilities, and can more accurately control the welding depth and width, meeting the high precision and high consistency requirements for battery module welding.

2. Improvement of production efficiency:

The ring-shaped spot 4+2 power laser has a high welding speed and can complete the welding of large areas or complex structures in a short time, significantly improving production efficiency.

The laser also has excellent stability and durability and can work continuously for a long time without being prone to failure, ensuring the continuity and stability of the production line.

3. Strong adaptability:

The ring-shaped spot design allows the laser to more flexibly adapt to the welding needs of battery modules of different shapes and sizes, without the need to frequently change welding tools or adjust welding parameters.

The 4+2 power configuration provides a wider power range to cope with welding challenges of different materials and thicknesses, ensuring welding quality and efficiency.

4. Cost-effectiveness:

Although the initial investment of the ring-spot 4+2 power laser may be higher, its efficient production capacity and excellent welding quality can significantly reduce subsequent maintenance costs and defective product rates, thereby achieving higher cost-effectiveness.

In addition, with the continuous development of technology and intensified market competition, the price of ring spot lasers is gradually decreasing, making them more market competitive.
