Abstract:
PCT No. PCT/DE91/00658 Sec. 371 Date Feb. 17, 1993 Sec. 102(e) Date Feb. 17, 1993 PCT Filed Aug. 16, 1991 PCT Pub. No. WO92/03725 PCT Pub. Date Mar. 5, 1992.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.
