Description

In 1980–81, Harwell developed a mini-computer controlled multi-probe defect detection and sizing system(l) based on the ultrasonic time-of-light/diffraction principle introduced by Silk(2). This system proved to be capable of fully automatic data collection from the PWR girth-weld simulation Plates 1 and 2 in the Defect Detection Trials of 1981–82. The speed of collection and subsequent analysis was such that a report on the defects found could be filed within 48 hours. The mode of operation adopted simulated minimum time of access to the defects, and was intended to define that dimension of a defect which has greatest significance, ie the through-thickness dimension.
