Module for assisting with the calibration of a device for testing metallurgical products comprising memory capable of storing data in the form of value/angle pairs. Each pair corresponds to an amplitude of response to an ultrasonic inspection in a direction of the metallurgical product corresponding to said angle. A computer is capable of executing a function for processing the stored data. A first set of data relates to a polydirectional reflector embedded in the metallurgical product. The pairs of the first set correspond to amplitudes of response to ultrasonic inspections in certain at least of the working directions of the polydirectional reflector. A second set of data relates to a directional reflector embedded in the metallurgical product. The second set of data comprises, for the directional reflector, at least one pair corresponding to an amplitude of response to an ultrasonic inspection in a working direction of the reflector. The processing function establishes a third set of data by interpolation of the pairs of the first set of data and of the second set of data. The pairs of the third set correspond to standard amplitudes for ultrasonic inspections in certain at least of the working directions of the polydirectional reflector.

A second electronic component is configured to process at least a portion of the signals captured by each of the elementary transducers. Each temporal law is arranged such that the corresponding burst produces a beam of ultrasonic waves which is generally divergent about the line of sight on moving away from the ultrasonic sensor.
