In ultrasonic machining, welding and mixing, a sonotrode is a tool that creates ultrasonic vibrations and applies this vibrational energy to a gas, liquid, solid or tissue.
A sonotrode usually consists of a stack of
resonant frequency of the tool, so the entire sonotrode acts as a half-wavelength resonator, vibrating lengthwise with standing waves at its resonant frequency. The standard frequencies used with ultrasonic sonotrodes range from 20 kHz to 70 kHz. The amplitude
of the vibration is small, about 13 to 130 micrometres.
Sonotrodes are made of
heat treatment (carbide). The shape of the sonotrode (round, square, with teeth, profiled ...), depends on the quantity of vibratory energy
and a physical constraint for a specific application. Its shape must be optimized for the particular application.
Sonotrodes of small diameter are sometimes called probes.
For an ultrasonic welding or cutting application, the sonotrode gives energy directly to the welding contact area, with little
wave propagation) could damage surrounding electronic components.[1]
