Abstract
An ultrasound testing device for the non-destructive testing of a workpiece wherein at least three testing heads are disposed on a testing head carrier, and the testing heads emit sound waves which converge at one or more intersections in an area of the workpiece so as to detect defects and determine the wall thickness. Operationally, the number of intersections is one less than the number of testing heads, and the separation between the sound waves is chosen so as to avoid the disturbances associated with utilization of oppositely situated testing heads. In addition, the device uses a flow medium to couple the testing heads to the surface of the workpiece.
