Ultrasonic Welding of Glassy Thermoplastic Polymers
Ultrasonic welding of thermoplastic polymers has been practiced industrially for many years without being fully understood. This study includes an analysis of the energy dissipation mechanisms responsible for the formation of ultrasonic welds in PMMA including viscoelastic loss and by plastic …

Failure analysis of a 30kHz ultrasonic welding transducer
Ultrasonic welding is used across variety of industries to join together thermoplastic materials. During ultrasonic welding, high frequency mechanical vibrations and compressive pressure are applied to the plastic materials. This creates intermolecular friction within the plastic which raises the …

A method of fabricating coated splices for oilfield applications
… finished splice. This project investigates how ultrasonic welding and injection molding can be employed in making the splice. After equipment and a process are designed, splices are produced and testing proceeds. Then an overall assessment of the method is made: connecting the wires in …
