Ultrasonic welding head introduction
Ultrasonic welding head is a general term for all ultrasonic transmitting ends, sometimes called ultrasonic mold. Its role is to couple the ultrasound generated by the transducer to the object being processed. Because it transmits ultrasonic waves, the welding head must work in a resonant state, that is, its natural resonance frequency must match the transducer; secondly, the amplitude must be uniform. The shape of the welding head end face should be adapted to the shape of the workpiece being welded.
