—Rapid performance and the absence of filler material in Ultrasonic welding has established itself as one the
most effective techniques in manufacturing industry for fusing plastic assemblies. Faster joining and reliable process for
developing plastic utility has increased in past decade. In Ultrasonic welding, by applying high-frequency vibratory
energy and pressure, thermoplastics materials are joined. Because of high-quality joints and low cost of Ultrasonic
welding of Thermoplastic materials has become a popular process in the industry. In this research, experimental data of
welding strength of acrylonitrile butadiene styrene (ABS) and Polycarbonate (PC) of material for ultrasonic welding are
studied. For the investigating the significant effect of process parameters of ultrasonic welding, various welding
parameters like Amplitude, Weld time and Welding Pressure and material thickness has been studied. In order to
determine critical states of the welding parameters. Taguchi Orthogonal Array method is employed as Design of
Experiments and analysis of variances has applied. Mathematical model was developed using Linear Regression method
and experiment was validated with confirmation Test.
