  • Device and method for the material testing and/or thickness measurements of a test object that contains at least fractions of electrically conductive and ferromagnetic material
    Patent number: 8037764
    Abstract: The invention relates to a device and a method for testing the material of a test object (4) which contains at least electrically conductive and ferromagnetic material fractions and has at least one engineered surface (5), by means of at least one electromagnetic ultrasonic transducer assembly (EMUS). Said assembly comprises a permanent or electromagnetic assembly (1) comprising at least two magnetic poles (N, S) of different magnetic polarity that face the engineered surface (5), in addition to an eddy current coil (2) that is placed in close proximity to the engineered surface (5) between the two magnetic poles (N, S) in indirect or direct relation to the engineered surface (5). The invention is characterized in that the eddy current coil (2) is configured and arranged in such a way that when said coil (2) is supplied with an alternating current, free ultrasonic waves that run essentially perpendicular to the engineered surface (5) are generated and propagate inside the test object (4).

  • METHOD AND DEVICE FOR AN IMAGING ULTRASONIC INSPECTION OF A THREE-DIMENSIONAL WORKPIECE
    Publication number: 20100064811
    Abstract: A method for an imaging ultrasonic inspection of a three-dimensional workpiece, in which ultrasonic waves are coupled into the workpiece with at least one ultrasonic transducer and ultrasonic waves reflected within the workpiece are received by ultrasonic transducers and converted into ultrasonic signals forming the basis of the non-destructive imaging ultrasonic inspection.
