With the development of automotive lightweight, aluminum alloy and other light alloys have also developed rapidly, high-power ultrasonic welding technology is one of the branches. In this paper, Cu and Al foils with thickness of 0.3 mm are welded by high-power ultrasonic welding method. Using relevant instruments for copper alloy organization characteristics, interface temperature, and interface mechanical properties test, the corresponding results found copper–aluminum current—compound ultrasonic welding, ultrasonic power peak, welding interface temperature and interface the depth, the vertical depth of the plastic flow and increases with increasing the thickness of the IMC as auxiliary current. Too high welding pressure is not conducive to the transmission of ultrasonic energy in the workpiece, reducing the quality of the workpiece connection. During ultrasonic welding, the texture strength of copper and aluminum alloy decreases first and then increases. The texture type of copper does not vary with the welding process.
