Difficulties In Laser Welding Square Aluminum Shell Batteries

At present, square aluminum shell batteries account for a large proportion of the entire power battery, but during the welding process, due to the particularity of the aluminum alloy shell, problems such as bumps and pores appear during the welding process, especially at the corners.

1. Battery raw materials

The casing of the power battery is made of aluminum alloy, which has the characteristics of easy forming, high temperature resistance, corrosion resistance, and conductivity. The main problem with aluminum alloy laser welding is due to the high emissivity and high thermal conductivity of aluminum alloys, making it difficult to perform.

2. Welding method

The thickness of the square battery shell is usually less than 1 mm, and the mainstream is 0.6 mm and 0.8 mm, while the laser welding of the square power battery shell mainly includes side welding and top welding. It will penetrate into the shell, but there will be protrusions during the welding process, which will affect the subsequent processing; the top welding is carried out on a plane, which has high requirements for the shell entry and positioning of the previous process, which requires a lot of High degree of automation.

3. Difficulties in welding

In the laser welding of aluminum materials, because the diameter of the optical fiber is too small, or because the laser power is set too high, problems such as bumps, pores, and bubbles will appear. There are many factors that affect spatter, including the characteristics of the material itself, The cleanliness of the material, etc., and the stability of the laser is the main factor affecting the laser.

1500w fiber laser welding machine

In production and assembly, the welding techniques of square aluminum shell lithium batteries mainly include: welding of soft joints of batteries and cover plates, welding of sealing nails, etc. Therefore, the selection of laser welding equipment should be customized according to the welding process requirements. Fly Laser Company can provide users with free proofing and laser welding scheme design, which can truly meet the needs of users for welding.
