Abstract
The invention relates to an ultrasonic process for testing, by immersion, the soundness of a metal piece (26) using at least one transducer (21) emitting ultrasonic waves focused in the piece (26). There are a plurality of transducers (21) used. Each of the transducers having in the tested piece (26) a focal spot at -6 dB, the section of which, perpendicular to the axis of propagation of the waves is less than 40 mm2. The focal spots of the transducers (21) being distributed depending on the depth to be tested of the piece (26). Additionally, the invention describes a process to guarantee the soundness of the interior of a piece (26), in particular a bar made of a titanium alloy (26) of a diameter of between about 50 and 400 mm for use in aeronautics.
