Introduction:

How does an Ultrasonic welder work? An Ultrasonic welder is a machine that uses kinetic energy from vibrations to heat and melt plastic together. The basic process comes down to a vibration frequency, measured in hertz, directing energy onto a section of the 2 parts you want to weld together.

The parts that are being welded are placed between the nest (commonly known as the anvil) and the sonotrode (commonly known as the horn). Both the horn and the nest is usually made from aluminium or titanium. The sonotrode is the connected to a transducer which emits the acoustic vibration. This vibration flows from the transducer, down the horn, and onto the part that is being welded. The frequency of the vibration can range from 15kHz all the way up to 70kHz.

The part design is usually critically. That part that contacts the horn, usually has a triangular lip that is protruding from the face that is being welded. The other part, that is contact with the nest, is held still and has a small groove that meets the protruding lip on the other part. The energy is concentrated into this lip, which is then heated and melted by the vibrations, and at a certain point this lips’ structure collapses and fills the groove with molten plastic.

Therefore, the ultrasonic horn is the part that directly works with the weldment, and the design of the ultrasonic horn affects the welding effect of the weldment. At the same time, the ultrasonic horn also belongs to the consumables in the entire welding system. Generally, the transducer and the ultrasonic power supply can work for 5 to 10 years, but the ultrasonic horns is available for several months to several years according to different working conditions.
