6 FAQs about [New energy lithium battery laser welding debugging]

Can laser welding be used in the production of lithium battery modules?

How does laser welding affect the temperature of lithium battery lugs?

1. The heat during the laser welding of lithium battery lugs is distributed centrally within the weld region, resulting in a significant temperature gradient in front of the molten pool and a smaller gradient at the rear. During the cooling process after welding, the temperature decreases rapidly within 5 s.

What is laser welding of lugs?

The laser welding of the lugs refers to the laser overlay welding of the lugs and the busbar, in which there are two types of materials for the lugs, namely 1060 aluminium alloy and TU1 oxygen-free copper, and the material for the busbar is 6061 aluminium alloy. The main chemical compositions of the materials are shown in Table 1.

What is laser welding & how does it work?
