Detailed description of the processing technology for copper aluminum transition plates and copper aluminum transition bars:
Definition of copper aluminum transition plate and copper aluminum transition bar
Product processing technology: (1) Flash welding (2) Friction welding
A: Flash welding instructions:
(1) The weld seam is complete and free from pores and cracks
(2) Horizontal misalignment shall not exceed 2.0mm, and thickness misalignment shall not exceed 0.7mm
(4) The surface of the copper aluminum plate is flat and smooth, with local scratches not exceeding 0.5mm
(5) The weld seam should not break when the copper aluminum transition is bent at 180 °
B: Friction welding instruction: Friction welding is a solid-state welding method that utilizes the heat generated by the mutual movement and friction of the workpiece end faces to achieve a thermoplastic state at the end, and then quickly break to complete the welding process
Friction welding process: (1) Mechanical energy is converted into thermal energy, (2) Material plastic deformation, (3) Forging pressure under thermoplasticity, (4) Molecular diffusion in crystallization

Connection Scheme of Busbars for Electric Vehicle Motors
Copper busbar, also known as copper busbar or copper busbar, is a long conductor made of copper material with a rectangular or chamfered (rounded) cross-section (now commonly used with rounded copper busbar to avoid tip discharge), which plays a role in conveying current and connecting electrical equipment in circuits.
What is the function of battery pack copper bars?
The power batteries of new energy vehicles need to rely on copper bars to connect with each other to form a high-voltage circuit. Copper bars are made of flexible or hard copper bars that can be bent. They are responsible for connecting various battery modules in the battery pack in series and playing a conductive role, with the characteristics of high current and high voltage loads.
How to choose copper busbar for electric vehicle power batteries?
Busbars, also known as busbars, are the main electrical connection solution between batteries and modules. According to the different materials, copper bars and aluminum bars are more common. Busbars are the connecting link between all high-voltage systems and socket connectors.
From the principle and process of continuous extrusion deformation, it can be seen that compared to traditional processes, continuous extrusion has the following advantages:
Factors affecting the quality of copper busbar
The surface quality of copper busbar can be divided into three main aspects: surface smoothness, surface flatness, and surface defects, which are closely related to copper properties, production processes, production management, and production environment.
