Welding characteristics of bi-metal, braided wires, aluminum and copper foils using 20 kHz ultrasonic complex vibration welding equipments

Welding characteristics of copper, bimetalic strip, braided flexible copper and tin coated copper wires consisted of thin wire elements, and large number of aluminum and copper thin foils are studied. Welding of copper, bimetal and braided wires and different metal foils are required for various electronic devices and multi-layer fuel cell, battery or EDLC electrodes for electric or hybrid automobile and various industry fields. These specimens are welded successfully using complex vibration welding.
