Abstract

The welding characteristics of large metal place specimens using an ultrasonic butt welding system with a 15-kHz large capacity vibration source are studied. The vibration source has eight 15-kHz bolt-clamped Langevin-type lead zirconate titanate (PZT) transducers of 60-mm diameter driven by a 50- or 100-kW static induction thyristor power amplifier. Aluminium plates of 6-mm thickness and 100-mm to 400-mm width are successfully joined end-to-end by changing welding tip driving positions. The required input power is about 2.2 kW/cm². Aluminium and copper plate specimens were also joined successfully by about 4 kW/cm² input power
