Abstract

Quadraphonic transmission ultrasonic defectoscopy (QTUD) is a new method of ultrasound. This paper presents a detailed and systematic view of the measuring procedure that enables the discovery of a necessary optimal balance between, on the one side, efficiency and reliability of the QTUD measuring system, and on the other, minimizing the investment costs in the measuring components precision. This type of defectoscope applies relatively low frequencies of just a few tens of kilohertz that enable the necessary signal penetration during the measuring procedure. This paper shows a defectoscopic examination of the standard aluminum material AlMg3 with a defect that has been purposely created in need of developing the QTUD measuring procedure, whereby varied wave forms and the amplitude levels of signal have been used for the purpose of their optimization.

Kurzfassung

Die quadrofonische Transmissions-Ultraschall-Defektoskopie QTUD ist ein neuartiges Ultraschall-Prüfverfahren. Die vorliegende Arbeit stellt sowohl das Prinzip als auch Einzelheiten der Messmethode dar, für die eine Ausgewogenheit zwischen Effizienz, Präzision und Zuverlässigkeit auf der einen und niedrigen Kosten der Komponenten des Messsystems auf der anderen Seite realisiert wird. Bei der vorgestellten Ausführung des Defektoskops werden relativ niedrige Ultraschallfrequenzen von einigen zehn Kilohertz eingesetzt, um eine hohe Signaltransmission zu erreichen. Die dargestellten Messergebnisse der Untersuchungen eines Probekörpers aus AlMg3 mit einem künstlichen Fehlerartefakt werden für die Entwicklungsprozedur des Ultraschallverfahrens eingesetzt. Für die weitere Optimierung werden unterschiedliche Signalformen und verschieden hohe Schallamplituden angewandt.
