Abstract: There is provided a system for cleaning a material. The system may include a tank, a plurality of ultrasonic transducer disposed within the tank. The material may be placed within the tank, which may be at least partially filled with a liquid. A computing device may be configured to activate the ultrasonic transducers so as to create constructive interference which generates ultrasonic shockwaves within a target zone within the tank to dislodge contaminants from a material located in the target zone.

Abstract: Provided is to ultrasonic probe used in scanning defect of welded zone of tube, the ultrasonic probe includes a probe body having a predetermined length, a connection bar connected to one end of the probe body, a phased array ultrasonic sensor installed on one side surface of the probe body to scan positions and shapes of the defects, and a pair of time of flight diffraction (TOFD) sensors respectively installed in the same line with the phased array ultrasonic sensor therebetween to scan depths of the defects. The present invention having the above-described configurations may significantly reduce a time taken to scan and accurately scan the positions, the shapes, and the depths of the defects.
