Abstract
A portable ultrasonic welding device for performing ultrasonic welding upon large, awkward, or odd-shaped workpieces is disclosed. The portable ultrasonic welding device comprises a housing inside of which are disposed a transducer, a horn, an interchangeable anvil, and an air actuator. The air actuator urges the anvil toward the cone to capture the workpiece. Due to its compact size and portability, the portable ultrasonic welding device may be hand held in positions and orientations which provide welds that could not be obtained with prior art devices. This flexibility in positioning and orientation also helps eliminate weld voids by assuring maximum contact of the anvil with the workpiece.
