The vibrations, through surface and intermolecular priciton, produce a temperature raise at the joint. When the temperature is high enough to melt the plastic, there is "flow" of material between the parts.When the vibrations stop, the materials solidified under pressure.(2) principle of system:A 50/60Hz, 220V line source feeds in a power supply generator supplies high frequency electrical energy to the "transducer" which changes this energy to machanical or vibratory energy. A booster preamplifies the amplitude or vibration produced at the faced of the horn, the purpose of the horn is to transfer the ultrasonic vibrations from the tranducer to the parts to be welded, and apply the necessary pressure to achieve a good weld.The transducer-booster-horn assembly is lowed and raised over the workpiece by a pneumatic system which brings the horn in contact with the part at a predetermined pressure and velocity. The transducer, booster and horn are mounted in the carriage, a movable housing in front of the welder. Fig. Shows the general arrangement of the major components.
