SIZE MEASUREMENT AND CHARACTERISATION OF WELD DEFECTS BY ULTRASONIC TESTING
Reports from the fabrication industry on the misinterpretation of defects with conventional manual ultrasonic testing have been widespread. Over-estimation of defects has resulted in unnecessary, expensive and time consuming repair and under-estimation may have led to significant defects being allowed into service. This paper reports on a program to define the problem by studying the interaction of ultrasound with weld defects using conventional equipment and assessment techniques, and to establish how the more recently developed and sophisticated techniques can be used to advantage. The present collaborative program of work is aimed to quantifying ultrasonic testing capability by providing detailed information on the application of both conventional and more specialized ultrasonic techniques to a large sample of defects and features in ferritic steel weldments in the 38 to 95mm thickness range.
