Abstract
In non-destructive testing (NDT) it is often preferable to test samples using several different techniques, in order to gain a higher probability of detection and a more reliable characterisation of each defect. However, this can lead to an increase in testing time and cost. A probe containing several NDT devices will give this accuracy and reliability, with the testing speed of using only one technique. We present initial results using a dual-probe containing a pulsed eddy current probe and a pair of electro-magnetic acoustic transducers generating ultrasonic surface waves in a pitch-catch manner. These two techniques are complimentary and are sensitive to surface and near surface defects, and no detrimental interference between the two techniques is observed. As both techniques are non-contact there is the possibility of use in hot or moving environments. The results from both can be combined using data fusion to give a higher probability of detection and more reliable sizing. Measurements of aluminium and steel samples containing manufactured and real defects are presented.
