Abstract
A method for structural component crack testing comprising: a) identifying a structural component hole and inserting a probe thereinto; b) for different emission directions, automatically performing the following: b1) controlling a probe ultrasound beam emission; b2) measuring a probe signal; b3) if the measured signal amplitude is above a predetermined threshold: determining a distance between the probe and a structural component discontinuity point; recording a data set comprising at least the distance between the probe and the discontinuity point, together with a data element corresponding to the probe emission angular direction, c) automatically searching for data sets corresponding to characteristic discontinuity points, and consequently establishing a correspondence between the probe emission angular directions and an angular reference frame linked to the component; d) based on the recorded data sets, automatically determining the discontinuity point positions; e) determining a dimensional characteristic of a crack based on the discontinuity point positions.
