Ultrasonic energy can be used to weld electrical grade, non-ferrous metals. There are several advantages that ultrasonic metal welding has over other joining methods, including superior electrical qualities and low-temperature rise during the weld process, which in most cases does not change the parent material properties.

Ultrasonic metal welding has been embraced as the standard for many manufacturing processes, including, battery manufacturing, automotive and appliance wire harness splicing, copper and aluminum metal tube manufacture and sealing, and the manufacture of heat transfer devices such as solar panels, automotive and electrical heat sinks.
