Laser welding of copper and aluminum busbars

Abstract

This utility model relates to the field of copper-aluminum busbar technology, specifically a laser-welded copper-aluminum busbar, comprising: a busbar body, a flat bend, a folded bend, a twisted bend, and a vertical bend; the flat bend and the folded bend are provided with a first welding part, and the twisted bend and the vertical bend are provided with a second welding part; the first welding part and the second welding part are laser-welded; the flat bend, folded bend, twisted bend, and vertical bend are sequentially arranged on the busbar body, forming a complex and orderly shape, meeting specific electrical connection requirements, and greatly improving space utilization; the first welding part connects the flat bend and the folded bend, ensuring a stable connection between the two parts; the second welding part connects the twisted bend and the vertical bend, achieving a high-strength and high-precision connection; the first welding part and the second welding part are laser-welded, resulting in fast welding speed; ensuring the strength and sealing of the welded parts, and improving the corrosion resistance and service life of the copper-aluminum busbar; the structure is compact and highly practical.
