Abstract

Bei einem Verfahren zum Erkennen und Lokalisieren von Materialfehlern, insbesondere zur Längsriss-, Längstiefenfehler- und Punktfehlererkennung, wobei mittels Wirbelstromprüfung zumindest eine Erregerspule (1) und zumindest eine Messspule (3) mit einem Material zusammenwirken, soll ein Signal (S1) der Messspule (3) and ein Signal (S2) der Erregerspule zueinander abgeglichen werden.
