Abstract
AbstractUltrasonic welding (USW) of metals is counted as a solid state consolidation of the involved parts, in which the growing interface temperature is far below the melting point of the material. This type of welding is a joining technique, in which a combined effect of the applied pressure and the ultrasonic frictional vibrations on the surface of the mating parts causes the formation of the bond. This contribution is devoted to study the coupled effect of the process parameters, namely the applied pressure and the amplitude of the ultrasonic vibrations on the interface temperature rise. Finally the result of the proposed thermo‐mechanical model are compared with the results from experiments in ultrasonic wire bonding.
