Blade lithium battery laser welding machine technical parameter

 Functions:

1. Battery tab welding

The tabs are usually divided into three materials. The positive electrode of the battery is made of aluminum, and the negative electrode is made of nickel or nickel-plated copper. In the manufacturing process of power batteries, one of the links is to weld the battery tabs and poles together. In the production of the secondary battery, it needs to be welded together with another aluminum safety valve. Welding not only needs to ensure a reliable connection between the lug and the pole, but also requires smooth and beautiful weld seams.

2. The power battery shell and the cover plate are sealed and welded

The casing materials of the power battery include aluminum alloy and stainless steel (stainless acid-resistant steel), among which aluminum alloy is used more, generally 3003 aluminum alloy, and a few use pure aluminum. Stainless steel is a laser weldable material, especially 304 stainless steel, whether it is pulsed or continuous laser, it can obtain welds with good appearance and performance.

The laser welding performance of aluminum and aluminum alloys (melting point 660°C) varies slightly depending on the welding method used. Except for pure aluminum and 3-series aluminum alloys, there is no problem with pulse welding and continuous welding, and continuous laser welding is used for other series of aluminum alloys to reduce crack sensitivity. At the same time, according to the thickness of the power battery shell, choose a Lithium Battery Laser Welding Machine with appropriate power (referring to the amount of work done by the object in unit time). Generally, when the shell thickness is less than 1mm, you can consider using a single-mode laser within 1000W. Use more than 1000W single-mode or multi-mode laser.
