ABSTRACT:
Apparatus for use with an ultrasonic plastic welder in which an ultrasonic horn on a movable welding head produces sonic vibrations along a first axis generally normal to the contacting surfaces of the workpieces to be welded together, the apparatus rendering the welder suitable for welding metals. The apparatus includes a coupling member removably connected to the distal end of the horn and extending transversely thereof and having coupled thereto a workpiece-engaging member capable of adjustment along a second axis parallel to the first axis. A force-applying member is connected to the welding head and extends therefrom toward the workpieces, with the workpiece-engaging member being adjusted to contact the lower end of the force-applying member at a fulcrum point so that axial vibration of the coupling means by the horn serves to pivot the workpiece-engaging member about the fulcrum point to effect a vibration transverse to the first axis at the contacted workpiece. Static force is applied to the workpieces along the second axis by the movable head acting through the force-applying member and the workpiece-engaging member.
