The development of ultrasonic welder for the formation of continuous welding seams.

The paper is devoted to the design of formation of continuous seam by the ultrasonic welding. The base of the device is developed vibrating system consisting of the piezoelectric transducer of longitudinal ultrasonic vibrations with the working tool, which provides the transformation of longitudinal vibrations into radial ones. Designed welder helps to achieve tight joint of thermoplastic materials with different thickness due to the regulation of broaching speed and amount of clearance between the bearing and the working tool.
