Description

Technical Field

[0002] Currently, the welding of copper bars and copper / copper-aluminum lap bars for output terminals on new energy vehicles is typically done using a single machine with a jig. This process exposes the product to air without protection, which can easily lead to surface oxidation during high-temperature welding. This leads to unstable welding temperatures and a lack of effective temperature control, which affects weld quality. After welding, the material is manually removed and immersed in cold water for cooling, and the workpiece cannot be quickly loaded and removed before and after welding. This process fails to meet the requirements for weld stability, poor oxidation appearance, and rapid production. This traditional high-frequency induction brazing process fails to meet the desired workpiece appearance and welding efficiency, lacks weld quality stability, and cannot meet the demands of rapid production. Furthermore, disassembly and assembly of the workpiece into the welding jig is cumbersome, significantly impacting production efficiency.
