The configurations of large-capacity 27 kHz ultrasonic complex vibration sources with eight longitudinal transducers and the welding characteristics of aluminum alloy plates using the complex vibration systems are studied. Ultrasonic complex systems are effective for various types of metal welding and are essential for new applications in various industries. The vibration source consists of a $(2, 1)$ mode transverse vibration disk (aluminum alloy), a complex transverse vibration horn with a welding tip (stainless steel) which is installed in the center of the disk, and eight bolt-clamped Langevin-type piezoelectric ceramic (PZT) transducers (BLTs) installed normally in both surfaces of the disk at an angle of 90° with respect to each other. The vibration source is driven using two systems at a phase difference of 90°. The transverse vibration rod installed at the center of the disk is driven transversally and the welding tip of the rod vibrates in a circular locus. Weld strength over 2500 N was obtained per welded spot area on 1.2-mm-thick aluminum alloy plates.
