Study on Ultrasonic Welding (3rd Report)

On design of coupling system of ultrasonoc welder

Abstract

Recently, ultrasonic welders of several types are fabricated and are widly employed for working or welding of various materials in Japan
In previous work, authors had studied about the following factors on joining properties of various materials, such as ultrasonic power, tip pressure, joining time, conditions of the materials to be joined etc. However, had not studied about the effect of coupling system design of welder on joining properties of various materials.
In this study, we have investigated about the effect of design of horn seemed to the most important of coupling system having influence on joining properties.
We have obtained some informations as to essential relations between joining properties and design of horn.
