Abstract: A test head for testing a workpiece has an ultrasonic transducer configuration with a plurality of ultrasonic transducers. The test head further contains a carrier matched to a surface contour of the workpiece, a damping layer arranged on the carrier, and a flexible conductor foil configuration, which is arranged on the damping layer and has a number of electrically separated conductor tracks which corresponds to the number of transducer elements. The transducer elements are arranged on the conductor tracks alongside one another in at least one row, and in each case are electrically contact-connected to one of the conductor tracks.

Abstract: An ultrasound probe contains an ultrasound transducer arrangement that is formed with a plurality of transducer elements. The transducer elements are arranged next to one another in a row and they can be controlled with a time delay. The transmitting/receiving surfaces of the transducer elements are inclined relative to one another such that the angle of inclination between the transmitting/receiving surfaces of two transducer elements increases with the number of transducer elements located between the transducer elements. At least two of the incremental angles of inclination between each pair of adjacent transducer elements are different.

Abstract: In a method and device for ultrasonic testing of a workpiece, a multiplicity of ultrasonic testing pulses are launched into the workpiece from a test surface thereof. At least two ultrasonic testing pulses are launched into the workpiece to be tested at launching points that are spaced apart from one another by a test step width measured along the test surface. A single measured value (?) assigned to a local point located in the workpiece is calculated on the basis of the received signals assigned to the at least two ultrasonic testing pulses.

Abstract: A method performs ultrasound testing of a test body having a hole extending in an axial direction. The method include disposing a test head within the hole. The test head extends in the axial direction and has sensor rings which are at a distance from one another and are disposed one behind the other in the axial direction. The sensor rings have a plurality of ultrasound transducers which are at a distance from one another. The ultrasound transducers disposed in a segment of each of the sensor rings extend in a circumferential direction of a respective sensor ring on at least a subsection of a circumference of the respective sensor ring. An ultrasound test pulse is injected into the test body. Measured values of first and second echo signals are evaluated to determine at least one of a location or an orientation of a fault in the test body.
