Ultrasonic welding

Ultrasonic welding

Piezos are used for ultrasonic welding with high-frequency ultrasonic acoustic vibrations. The vibrations are applied to two parts by a vibrating tool. The actual welding is a result of the heat and agitation generated at the interface between the parts or surfaces. Ultrasonic welding can be used for plastics and different metals. There are no connective bolts, nails etc. necessary to bind the materials together.

How ultrasonic welding works
The piezoelectric effect allows the conversion of high-frequency electrical energy to high-frequency mechanical energy. When the high-frequency vibrations are transferred to the materials being welded, frictional heat is generated where the two materials meet, leading to a local softening or melting. This, together with the mechanical agitation, leads to a solid weld, without the addition of material.

Which piezo elements can be used for ultrasonic welding?
The transducer in the ultrasonic welding device is typically fitted with one or more monolayer elements. A typical design for the piezo element would be a ring of one of our hard doped piezoceramic materials, such as NCE80. This should be driven at high field to provide the highest mechanical power without excessive self-heating. The movement of the piezo element is amplified using a sonotrode or “horn”.
