Abstract

Abstract: The ultrasonic welding (UW) technique is an ultrafast joining process, and it is used to join thermoplastic composite structures, and provides an excellent bonding strength. It is more cost efficient as opposed to the conventional adhesive mechanical and other joining methods. In the paper, an ultrasonic atomization welding system is discussed, which composed of the high frequency ultrasonic power supply and the transducer. The high frequency ultrasonic power supply provides appropriate electric for the transducer, and the transducer transforms the electric energy into the ultrasonic kinetic energy. This project is focus on the theory analysis and the design of the mechanical system. Based on the analysis and argument ofultrasonic welding power, for ultrasonic welding of the specific requirements, other parts, gave the parameters ofcalculation and choice of methods.Keywords- ultrasonic welding, transducer, kinetic energy
