PROCEDE ET DISPOSITIF PERMETTANT LE SOUDAGE ULTRASONIQUE DE FILS SUR LASURFACE METALLIQUE D'UN SUPPORT

摘要

A method of and a device for the ultrasonic welding of wires comprising a non-metal insulating layer on the metal surface of a support by means of a welding tip which is made to vibrate in a direction parallel to the longitudinal direction of a wire to be welded; according to a previously programmed welding cycle, the insulating layer is first removed locally and the wire is then welded; a preceding mechanical or chemical cleaning of the wires is not necessary.
