摘要： A method and a device for the ultrasonic testing of a workpiece having an uneven surface is provided. An ultrasonic test head containing a multiplicity of transducer elements arranged rigidly in a linear array, is acoustically coupled to a workpiece. The ultrasonic test head can be driven in a time-delayed manner with a delay time predetermined for each transducer element. The propagation time of an ultrasonic signal transmitted by an individual transducer element and reflected from the surface and received by this transducer element is measured for a number of the transducer elements and is used for correcting the delay times. The transducer elements are subsequently driven with these corrected delay times.

摘要： A method for the production of ultrasound waves for nondestructive materials testing of a workpiece. The method includes providing at least one radio frequency coil disposed in an essentially uniform magnetic field. The at least one radio frequency coil has a longitudinal axis disposed parallel to a surface of a workpiece. The method also includes producing horizontally polarized transverse ultrasound waves in the workpiece due to an interaction of the magnetic field with eddy currents in the workpiece. The eddy currents are supplied by the at least one radio frequency coil. The invention also teaches a device for implementing the method.
