The probe configuration in ultrasonic welding typically consists of a converter, a booster, and a horn.

The converter is a piezoelectric transducer that converts electrical energy into mechanical vibration. The booster is a metal component that amplifies and modifies the amplitude and displacement of the vibration generated by the converter. The horn is attached to the end of the booster and transmits the vibration to the parts being welded. The shape and size of the horn are customized for each specific application to optimize the weld process.

The configuration of the probe can significantly impact the weld quality and efficiency, and it is important to select the appropriate configuration based on the materials being welded and the requirements of the application.
