Abstract
A method of joining the ends of wire windings for a motor stator or the like includes preparing a surface at each end (e.g., by removing any enamel coating), deforming the surfaces to produce knurls, striations, and the like, and then ultrasonically bonding the two surfaces to produce the bond between windings, thereby providing a joint with improved strength.
