Ultraschallschweißen von Kontaktwerkstoffen

Ultrasonic Welding of Contact Materials . Ultrasonic welding of metals has found only a few industrial applications until now. Today however ultrasonic welding equipments with high power output for the welding of thicker parts are available. Contact materials have been welded ultrasonically on various base materials, e. g. silver and silver alloys on copper and copper alloys and aluminium. Bond quality was determined by shearing off the contact plates from the base material. Metallographic investigations and microhardness measurements were made to examine the bonding mechanisme. Ultrasonic welding will be a very good supplementary method in contact technology mainly for the welding of hardly weldable components like AgCdO or Al.
