International Journal of Materials and Product Technology (IJMPT), Vol. 33, No. 4, 2008

Abstract: Ultrasonic technique has been successfully used in a Non-Destructive Testing (NDT) of materials. This method aims to characterise the physical properties of reflectors in terms of their location, size, orientation, etc. To perform ultrasonic NDT, a transmitting/receiving transducer is moved along a known path producing a reflectivity map of the tested material. In order to characterise flaws, an innovative methodology of ARTMAP network and Wavelet Transform is presented. It consists of two non-supervised networks which are then used to build a mapfield. The mapfield is constructed using the neural networks output trained with time-scale information of perpendicular reflectivity maps.
