Abstract
Ultrasonic welding of thin metal plates using a complex vibration welding tip is studied. The welding tip vibration locus shape is changed from linear, elliptical, to circular using a pair of the same frequency 27 kHz complex vibration systems. Aluminum and copper plate specimens of 0.5 to 1.0 mm thickness were welded successfully using this welding system. Required vibration amplitude is about half compare to a conventional system. Weld strength and weld area obtain by this system are larger, and welded area becomes more concentrated than these by a conventional system. The weld strength also was independent of specimen direction.Keywords
