Copper-aluminum transition plate and copper-aluminum transition row processing technology
Description of copper-aluminum transition plate and copper-aluminum transitional processing technology:
 
Copper-aluminum transition plate, copper-aluminum transition row definition: This product has high composite strength and realizes the contact surface compounding between copper and aluminum. It is suitable for the connection between copper busbar and aluminum busbar of power plants and substations, and is also widely used in the conductive industry. (eg transformer, equipment, electrical, mechanical, etc.) requires a connection between copper and aluminum connections
 

Product processing technology:
(1) flash welding (2) friction welding
 
A: Flash welding instructions:
 
(1) Complete weld, no porosity and crack
 
(2) The wrong side of the water plane does not exceed 2.0mm, and the thickness of the wrong side does not exceed 0.7mm
 
(4) The surface of the copper and aluminum plate is smooth and smooth, and the local scratch is not more than 0.5mm.
 
(5) The weld should not break when the copper-aluminum transition is bent at 180°
 
B: Friction welding description:

Friction welding is a solid-state welding method for achieving welding. It is a method of using the heat generated by the mutual movement of the workpiece end faces and rubbing each other to make the end portion reach the thermoplastic state, and then quickly breaking off to complete the welding.
 
Friction welding step process:
(1) mechanical energy is converted into thermal energy
(2) plastic deformation of material
(3) thermoplastic forging pressure
(4) intermolecular diffusion in crystallization
