Abstract

Complex vibration ultrasonic lap spot welding systems of 100 kHz are studied. The complex vibration welding tip vibrates in elliptical locus. Welding characteristics of 100 kHz, 60 kHz, 40 kHz and 27 kHz complex vibration systems with a longitudinal-torsional vibration converter were compared using aluminum plate specimens. Aluminum plates were welded independent to the directions between welding tip vibration direction and specimens. The vibration amplitudes of the welding systems required for obtaining sufficient weld strength become smaller, as the vibration frequencies become higher. The required vibration amplitude of aluminum plate specimens the 100 kHz system was smallest among them
