Ultrasonic Characterization of Flaws
Results obtained from the ultrasonic inspection of tubes and other parts may not be satisfactory due to insufficient sensitivity and inability to characterize a flaw (i.e. determine its shape and orientation) and then size it. It is therefore worth to develop some special approach, which could significantly improve inspection capabilities by using some simple techniques. For example, one can employ a few transducers positioned differently and working in parallel. The obtained image will contain a number of responses, related to various transducers. Combining these data, one can evaluate flaw shape and orientation, as well as estimate its dimensions.
