An ultrasound method and device for inspecting the bulk of a weld for the presence of defects are provided. The method includes a step of studying the weld metallurgically; a step of dividing the weld 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 through the weld; a step of simulating at least one reference diffracted ultrasound wave; a step of emitting at least one incident ultrasound wave into the weld; a step of measuring each diffracted ultrasound wave; and a step of comparing each reference diffracted ultrasound wave with each measured diffracted ultrasound wave. |
