Using Ultrasonic Transducers in Welding Applications
Ultrasonic vibrations produced by piezoelectric ceramic elements can be used to generate heat to weld or melt thermoplastics.
In order for an ultrasonic transducer to be used in a welding application the longitudinal vibrations on the end of the transducer need to be amplified and concentrated onto a small surface area. This is accomplished through the use of an amplitude transformer, or horn, manufactured from a titanium or aluminum alloy.
In ultrasonic welding, the horn is brought into contact with one piece of thermoplastic that is to be joined to another piece. Pressure is applied to the two pieces of thermoplastic and the ultrasonic vibrations pass through the first piece to the interface with the second piece. Frictional heat at this interface will melt the material and once the vibrations stop, the temperature drops, and the plastic solidifies the two pieces of plastic will have bonded together.
Using ultrasonic transducers for welding is beneficial because it is:
- Fast and efficient
- Produces a strong bond
- Eliminates the use of solvents and adhesives
- and Heat generated is confined and thus rapidly dissipated
If you're interested in developing a piezo transducer for use in a welding application or have any questions about the ultrasonic welding process, please contact an APC Sales Representative today!
