Laser welding machine technical requirement
This laser welding machine is mainly used for welding the prismatic or pouch pack. Welding material: aluminum, copper, nickel, etc. Welding seam is beautiful and welding seam width＞1mm. A
protective cover is required around the welding machine, and a fume absorber device is required. In addition, a protective gas purge device is required.
The specific requirements of the equipment are as follows:
1）The welding thickness 3mm.
2）The stroke: X=1000mm, Y=800mm Z=400mm.
3）Welding speed≥1mm/s.
4）Laser type: CW.
5）Laser power: 6000W.
6）Laser working medium: optical fiber.
7）Laser working mode: single mode/multimode.
8）Laser service life: ≥5 years.
9）Pressing tool: 2pc for prismatic cell.
Process
- 1) Welding material: aluminum bus bar, copper bus bar, nickel tab.
- 2) Two modes of welding are available: CW and pulse spot welding.
- 3) Welding point penetration: 0.6±0.2mm or specified by Party A.
- 4) The tensile strength of welding point is greater than the destructive strength of material.
