Abstract
An ultrasonic resistance welding apparatuscontains a resistance spot welding apparatus, a first electrodeand a vibrable second electrode, the vibrable second electrodein operable communication with an ultrasonic transducer, whereby the ultrasonic transducerselectively imparts vibratory energy to the vibrable second electrodebased on signals from a controller. The vibrable second electrodemay be tuned or designed to resonate within 2.5% of an operating frequency of the ultrasonic transducer. During operation of the welding apparatus, a tipof the second vibrable electrodemay be positioned at an anti-nodal pointof the vibratory energy and the vibrable second electrodemay be attached to the resistance spot welding apparatusat a nodal planeof the vibratory energy. A process for employing the apparatusis also presented.
