Example Embodiment
[0067] Example one:
[0068] The battery tab 10 is bent and attached to the bus bar 20, and the battery tab 10 and the bus bar 20 are connected as a whole through an outer frame bracket, so that they remain relatively fixed. The battery tab 10 and the bus bar 20, which are integrated as a whole, are fixedly placed on a welding platform. The welding platform is moved so that the area to be welded 30 between the battery tab 10 and the bus bar 20 is placed at the initial welding position. This initial welding position makes one end of the area to be welded 30 correspond to the spot position of the laser beam of the laser welding device.
[0069] The battery tab 10 is made of pure copper, and the bus bar 20 is made of pure aluminum.
[0070] Select a laser welding device, wherein: the transmission fiber core diameter of the laser welding device is 10 μm, the optical amplification ratio of the laser beam is 1:1, and the laser output power is 500W.
[0071] The laser beam spot is welded a...

[0072] Embodiment two:
[0073] The battery tab 10 is bent and attached to the bus bar 20, and the battery tab 10 and the bus bar 20 are connected as a whole through an outer frame bracket, so that they remain relatively fixed. The battery tab 10 and the bus bar 20, which are integrated as a whole, are fixedly placed on a welding platform. The welding platform is moved so that the area to be welded 30 between the battery tab 10 and the bus bar 20 is placed at the initial welding position. This initial welding position makes one end of the area to be welded 30 correspond to the spot position of the laser beam of the laser welding device.
[0074] Wherein, the battery tab 10 is made of pure aluminum, and the busbar 20 is made of pure copper.
[0075] Select a laser welding device, wherein: the transmission fiber core diameter of the laser welding device is 20 μm, the optical amplification ratio of the laser beam is 1:2, and the laser output power is 1200W.
[0076] The laser beam spot...
