The ultrasonic cleaning tank is similar to a container, containing cleaning solution and the washed parts. In general, the transducer is directly connected (bonded or welded) to the bottom of the cleaning tank, and the cleaning tank is used as an ultrasonic vibration radiation plate. In order to have good corrosion resistance, fatigue resistance, and sound conductivity, cleaning tanks or ultrasonic vibration radiation plates are commonly made of stainless steel.
