An apparatus and method for ultrasonically welding wires includes an ultrasonic horn tip and associated structure for allowing adjustment to accommodate different diameters of wires to be welded while maintaining a tight grip around the wires during the welding process to avoid spreading or splaying of the wires. The tip is rotable to provide several alternative and interchangeable work surfaces on a standard-shaped readily machineable cross section, thereby allowing for a longer total worklife and a reduced cost of manufacture.

A device for ultrasonically welding workpieces, comprising: an ultrasonic horn which produces ultrasonic vibrations, said ultrasonic horn having a welding tip with a first work surface disposed parallel to the axis of the ultrasonic vibrations; an adjustably sized channel for retaining and compressing said workpieces during the welding process, said adjustably sized channel comprising: a gathering tool slidably mounted for back and forth movement parallel to said first work surface and having a second work surface facing into the interior of said adjustably sized channel and disposed at right angles to said first work surface; an anvil adjustably mounted with respect to the first work surface, said anvil having a third work surface facing into the interior of said adjustably sized channel and disposed opposite and facing the first work surface of said head; a support having a fourth work surface facing into the interior of said adjustably sized channel and disposed normal to said first work surface and extending at least between said first and third work surfaces whereby said adjustably sized channel is defined by the first, second, third and fourth work surfaces; means for decreasing the size of said adjustably sized channel comprising: means for moving said second work surface towards said fourth work surface whereby the workpieces are compressed between said gathering tool and said support; and means for moving said gathering tool and said horn tip towards said anvil whereby the workpieces are compressed between the welding tip and the anvil.
