ABSTRACT:
Metallic workpieces, such as the terminals of a direct current motor armature winding, are welded to a slot, such as a commutator slot, using high frequency vibratory energy. A half wavelength resonator including a tip having a cutting surface is disposed opposite a slot containing the workpieces. As an applied force urges the tip into relative motion with respect to the slot, the cutting surface cleaves a sliver from the slot wall, the sliver being urged by the tip into intimate contact with the workpieces to be welded. When the resonator is rendered resonant for undergoing high frequency vibratory motion in a direction normal to the applied force the sliver and workpieces are welded together and to a surface of the slot.
