<p>This method comprises a step of studying the weld (10) metallurgically; a step of dividing the weld (10) into a plurality of theoretical blocks and of jointly determining an elastic Hooke tensor for each theoretical block; a step of simulating by calculation the propagation of at least one incident ultrasound wave (73) through the weld (10); a step of simulating at least one reference diffracted ultrasound wave; a step of emitting at least one incident ultrasound wave (73) into the weld (10); a step of measuring each diffracted ultrasound wave (75); and a step of comparing each reference diffracted ultrasound wave with each measured diffracted ultrasound wave (75).</p> |
