Abstract

Ultrasonic welding is the mostwidely used and fastest known welding technique for joining of thermoplastic materials. The process uses high frequency vibrational energy to produce low amplitude mechanical vibrations. These vibrations cause generation of heat at joint interface of the parts being welded, the heat generated is sufficient for melting of the thermoplastic materials and after cooling weld formation takes place. The fundamental aim of this study is to investigate the effect of welding parameters such as amplitude, pressure, weld time and thickness ratio on weld strength of thermoplastic materials. The thermoplastic materials such as Acrylic, Polycarbonate andPolypropylene are selected for this study. An experimentalmodel based on full factorial design is selected and experiments are performed as per Design of Experiment. The significantly affecting process parameters are identified and ranked using analysis of variance (ANOVA) method. The outcome of this study is to identify the weld strength obtained in different thermoplastic materials for a selected range of process parameters
