The inspection of ultrasonically noisy steels (using commercially available signal processing routines)

The author describes the study of the propagation of ultrasound through ferritic plate material containing a range of inclusion populations in order to identify those parameters which are significant in understanding the interaction of ultrasound with inclusions and in quantifying inspection performance. In particular he considers the benefits which can be derived from the use of standard commercial packages (both hardware and software) in the development of data collection and display systems
