Abstract :
Complex vibration ultrasonic lap spot and seam welding systems of 27 kHz and 40 kHz are studied. Welding characteristics of 27 kHz and 40 kHz complex vibration lap spot welding systems with a longitudinal-torsional vibration converter were compared using aluminum plate specimens. And also, a lap seam welding system with a complex vibration disk welding tip was designed. Aluminum plates of various thickness were continuously joined at multiple positions uniformly using the complex vibration system.
