Ultrasonic butt welding of thick metal plate specimens is studied. Welding specimens used are aluminium, anticorrosive aluminium, and copper plates of 6-mm thickness. These welding specimens are successfully joined end to end with specimen strength of about 100 MPa (pure aluminium) or 250 MPa (anticorrosive aluminium) using 26-kHz or 19-kHz butt welding equipment. An ultrasonic vibration source of 19 kHz uses eight bolt-clamped Langevin-type PZT transducers of 50-mm diameter. The power required for joining aluminium, anticorrosive aluminium specimens, and anticorrosive aluminium to copper specimens is found to be 1-3 kW/cm/sup 2/, 6-8 kW/cm/sup 2/, and 7-9 kW/cm/sup 2/, respectively.
