Abstract

The application of ultrasonic welding has increased over the last decade due to the rapid technological development and its availability at lower cost. In this paper ultrasonic welding of conductors is presented as one of the most important manufacturing processes in the automotive industry. Using this method of welding, conductor joints are created that represent a crucial part of any electrical installation such as wiring harnesses for vehicles. Additionally, connections between conductors and components, such as metal terminals, can also be achieved using the same welding process. These conductor joints or connections between conductors and terminals must provide high electrical conductivity and satisfying mechanical properties in order to create a safe and reliable product. The conclusions of this study provide some advantages of ultrasonic welding application, particularly in the automotive industry, and further trends in this field.
