Abstract :
This paper describes an experimental study on ultrasonic welding of aluminum and copper alloy. There are several welding techniques which are expected to replace other welding and brazing processes. In this study the relation between energy density and welding pressure in welding certain types of aluminum alloys was clarified. The welding energy is effectively used in the ultrasonic welding of a flexible, narrow material with a narrow pressurization area. The ultrasonic welding of Al/Cu can be accomplished when the conditions of amplitude: 15 μm, welding pressure: 20 MPa, at a required duration of 1.0 s under the water bath. Furthermore, the oxide film and organic coating are periodically removed from bonded interfaces by ultrasonic wave vibration, and it can be expected to form transition layer of 1–2 μm at the bonded interface.
