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 has been studied. In order to determine critical states of the
welding parameters, Full Factorial methods is employed as Design of Experiments and analysis of variances has applied
while optimization of the parameters affecting the welding strength has been achieved with the Response Surface
Methodology.
