The configurations of large-capacity 27 kHz ultrasonic complex vibration sources with multiple longitudinal transducers are proposed and studied. Ultrasonic complex vibration systems are effective for various types of metal welding and essential for new applications in various industries. The large-capacity vibration source consists of a complex transverse rod with a welding tip (titanium alloy), a complex vibration rod with a flange and a stepped part for holding the system (stainless-steel), a one-wavelength longitudinal vibration disk (aluminum alloy) and six bolt-clamped Langevin type piezo-electric ceramic (PZT) transducers (BLTs) installed along the circumference of the disk at an angle difference of 60°. The vibration source is driven using three driving systems with three transformers at a phase difference of 120°, and the disk is driven in a circular locus. 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.
