A novel ultrasonic technique for material testing

Abstract

The material defectoscopy method that uses separate ultrasonic heads for emitting and reception of signals, i.e. ultrasonic transmission defectoscopy, hasn't been in use in science and engineering that much until now. This method consists of an ultrasonic head for emitting the signal and a single ultrasonic head for the reception of the signal. The method described in this paper is named "Quadrophonic Transmission Ultrasonic Defectoscopy" (QTUD). It is an ultrasonic defectoscopy method for material testing that uses a single ultrasonic head for emitting and four ultrasonic heads for receiving the ultrasonic signal. The prime advantage of the QTUD method is its real life applicability even with porous materials, and the basis for the method on relatively low frequencies (only a few tens of kHz). Because electronic components are very cheap to acquire, therefore, the wide application of this method, both in science and industry, is very likely.
