The
ultrasonic welding transducer is similar to the cleaning transducer in principle. It is also used to compensate the expansion stress of piezoelectric ceramics by applying prestress to achieve high frequency vibration with large amplitude. Because the welding transducer requires a great instantaneous power, it has a high demand for materials and technology, is a high-power acoustic super-energy. Usually, the ultrasonic welding of plastics, metals and other materials is accomplished by the vibration system with the characteristics of high power and large amplitude combined with the horn and working head.
Ultrasonic welding is the ultrasonic vibration produced by transducers, which produces high-frequency friction and heat on the surface of the contact gap of the welded object under compression, so as to achieve the purpose of heat fusion welding.
Ultrasonic welding transducer is a kind of high-power transducer with gap or pulse operation. Its power is usually calculated by instantaneous peak power.
