A MICROCOMPUTER AID TO OPERATOR-BASED WELD INSPECTION

A simple microprocessor-based electronic aid to assist the operator of manual inspection systems is described. The problems of probe-positioning and a-scan interpretation are solved by using a surface-wave positioning unit and electronic processing of defect data. In this way a larger number of individual measurements on a particular defect can be made with a subsequent improvement in accuracy. Also due to the electronic processing a hard copy output is readily available either as a plotted graph or printed data.(a) (TRRL)
