Abstract

Bei dem vorliegenden Verfahren zum Erzeugen von Ultraschallwellen (4) zur zerstörungsfreien Werkstoffprüfung eines Werkstückes (24), mit wenigstens einer in einem im wesentlichen homogenen Magnetfeld (26) angeordneten Hochfrequenz-Spule (12-18), deren Längsachse (20) parallel zur Oberfläche (22) des Werkstückes (24) angeordnet ist, werden aufgrund der Wechselwirkung des Magnetfeldes (26) mit den von der Hochfrequenz-Spule (12-18) im Werkstück (24) erzeugten Wirbelströmen horizontal polarisierter transversaler Ultraschallwellen (4) in diesem erzeugt. Durch diese Maßnahme ist ein einfaches Erzeugen von horizontal polarisierten transversalen Ultraschallwellen (4) gewährleistet.

In the present method for generating ultrasonic waves (4) for non-destructive material testing of a workpiece (24), with at least one high-frequency coil (12-18) arranged in an essentially homogeneous magnetic field (26), its longitudinal axis (20) parallel to the surface (22) of the workpiece (24) is arranged, because of the interaction of the magnetic field (26) with the eddy currents generated by the high-frequency coil (12-18) in the workpiece (24), horizontally polarized transverse ultrasonic waves (4) are generated therein. This measure ensures simple generation of horizontally polarized transverse ultrasonic waves (4).
