ABSTRACT:
A method of inspecting a part in immersion using a focused beam of ultrasound waves oriented perpendicularly to the surface of the part, the method including, when the axis of the focused beam is close to an edge of the part, tilting the axis towards the edge relative to the normal to the surface of the part in order to eliminate the lateral shadow zone over all or substantially all of the depth of the part.
