Experimental Investigation of Ultrasonic Welding on Thermoplastic Material – A Review

Abstract

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 without melting. 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 tensile strength of acrylonitrile butadiene styrene (ABS) and Polycarbonate (PC) of material for ultrasonic welding on welding parameters like Amplitude, Weld time and Welding Pressure has been studied. Analysis of Variation (ANOVA) and Full Factorial method are used to determine the critical states and effects of the welding parameters.

Interdependence of Technical and Technological Parameters in Polymer Ultrasonic Welding

“…The functional dependence of a decrease in ultrasound intensity in a material with distance (thickness) is defined by Equation (11):…”

“…In their research related to the development of textile-based transmission lines using conductive yarns and ultrasonic welding technology for e-textile applications, O. Atalay et al [10] mention only strength and compression force as process parameters. Based on a literature review of ultrasonic welding of thermoplastic material like most influential process parameters A. K. Makawana and V. R. Patel [11] list amplitude, weld pressure and welding time. S. K. Bhudolia et al [1] reviewed advances in ultrasonic welding of thermoplastic composites and listed welding time, frequency, amplitude and compression force as process parameters.…”
