A Review of Studies on Ultrasonic Welding

Abstract

This review work is to summarise the results of the experimental studies on ultrasonic welding of
thermoplastics, blends of thermoplastic polymers and composites at Department of Engineering Technology, Technical
University of Liberec, Czech Republic. The previous studies were focused on determining the effect of selected
technological parameters in ultrasonic welding process, of different energy director shapes and of filler percentages in
the thermoplastic matrix on the tensile strength of the welded joint under various welding conditions. In addition, this
review also mentions the further research directions in this field.
