Ultrasonic welding is based on high-frequency vibrations (typically between 20 and 40 kHz) that cause surface friction and viscoelastic heating at the weld. The most important process parameters are ...

This article overviews the ultrasonic welding process, a solid-state joining method, using the example of welding of a magnesium alloy as well as the joining of magnesium alloys in general. In situ ...

Abstract: Utrasonic treatment of the solidifying metal is a promising method for improving the quality of fusion welding. A method to combine the ultrasonic waves to the welding process using ...

The Ultrasonic Additive Manufacturing process uses sheets or ribbons of metal, which are bound together using ultrasonic welding. The process does require additional cnc machining and removal of the ...

This method uses ultrasonic vibrations to melt the work piece and use that melted piece to join them. This machine does not use any extra soldering materials, bolts, nails or adhesives to join the ...

Source: Proven Process Medical Devices, Inc. Ultrasonic welding is particularly suited for bonding medical devices because it uses the device material itself to form a bond and does not introduce ...

However, one major disadvantage of electric resistance welding process is that it produces very few heat-affected zones (HAZ). This could cause problems when welds need to be tested or inspected ...

They link individual battery cells to make a full battery pack. However, the process of making joints has evolved over the years due to various technologies. This first part of the multipart FAQ will ...

An ultrasonic welder that can join painted plastic parts in automotive applications is among four new welding technologies featured this month. Engineers at the Graz University of Technology (TU Graz) ...
