摘要: The invention is directed to a u/s test device for nondestructive testing of a workpiece moving relative thereto by the pulse echo method, having a fluid coupling between the ultrasonic oscillator and the surface of the work material. At least two test heads are provided whose sound beam axes intersect at a point in the region of the workpiece and a travel path in the form of a chamber is provided for guiding the fluid medium. To reduce susceptibility to interference and to achieve high test performance, a separately guided travel path extending along a determined length of the chamber and forming a duct (12-20) is associated with each test head (1-9), the axes of the travel path being aligned with the respective sound beam axis.

摘要: 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.
