Abstract

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.
