ULTRASONIC FLAW DETECTION AND CHARACTERISATION--AN AUSTRALIAN VIEW

The ultrasonic testing of welds is a particularly contentious subject. It is hardly surprising that highly divergent views exist regarding the capabilities of the method with respect to an application which requires the detection of flaws of a variety of types, orientation and position. This is demonstrated by the different approaches reflected in codes and specifications applicable to weld testing. If consistent and comparable test results are to be obtained, there is clearly a need for a unified approach to the methods of test to be applied to welds and to the manner in which test results are presented. In Australia, a move has been made in this direction by the recent publication of Australian Standard 2207-1979, "Methods for the Ultrasonic Testing of Fusion Welded Joints in Steel". This paper discusses the problem of reproducibility of test results. A large variability of test results was found to result from differing probe and instrument characteristics. The need for standards and specifications to better reflect the capabilities of N.D.T. methods is emphasized.
