Abstract
The trial system by a unit transmitter emits ultrasonic waves on the side solid material. A solid body rotated every multiple 20˚ of 0-180˚ to get an angle variations. The result obtained that waves as 40 khz can detect the form of solid material defect. The form of defect in a solid material has different wave pattern. Constant wave patterns with small amplitudo is a cylindrical material without defect, constant wave patterns with more much amplitudo is cylindrical material with cylindrical defect also and wave patterns whose amplitudo is different in any variation angle is cylindrical solid with cubicaly defect.
