Ultrasonic Welding of Alumina/Aluminum Using Inserts

Abstract

This paper gives a description of an experimental study of ultrasonic welding of aluminum and alumina by using inserts. For example, the ultrasonic welding of 5N-Al sheet (0.2t) and anodized aluminum by means of vaporized aluminum (5N-Al, A1050, A2017, A6061, A7075) as inserts can be accomplished under condition of 5MPa and 0.1s. With the exception of vapor-deposited 5N-Al film, the vaporized film used for auxiliary purpose played a role of binders to facilitate welding, with short welding time and with low welding pressure, but much difference in welding strength was not found the welds with each aluminum alloy.
