Abstract

La présente invention se rapporte à un transducteur ultrasonique (1) est destiné au contrôle par ultrasons d'une zone de soudure, ledit transducteur comprend une pluralité d'éléments émetteurs/récepteurs (3) d'ondes ultrasonores destinés à émettre des ondes ultrasonores en direction de la zone de soudure et à recevoir des ondes ultrasonores réfléchies sur la zone de soudure, les éléments émetteurs /récepteurs (3) d'ondes ultrasonores sont agencés de façon à obtenir un transducteur ultrasonique avec une surface de détection formée par au moins deux ensembles d'éléments émetteurs/récepteurs d'ondes ultrasonores qui s'étendent suivant au moins deux directions différentes (X, Y), chaque ensemble d'éléments émetteurs /récepteurs (3) d'ondes ultrasonores comprend au moins un alignement d'éléments émetteurs/récepteurs d'ondes ultrasonores, il est caractérisé en ce qu'au moins un élément émetteur/récepteur d'ondes ultrasonores est disposé à l'intersection des deux directions. La position d'un élément émetteur/récepteur au centre soit à l'intersection des deux directions permet, dans le cas d'un point de soudure, de détecter la présence d'une retassure au centre du point soudé.The present invention relates to an ultrasonic transducer (1) is intended for the ultrasonic inspection of a weld zone, said transducer comprises a plurality of ultrasonic wave emitter/receiver elements (3) intended to emit ultrasonic waves in direction of the weld zone and to receive ultrasonic waves reflected on the weld zone, the ultrasonic wave transmitter/receiver elements (3) are arranged so as to obtain an ultrasonic transducer with a detection surface formed by at least two sets of ultrasonic wave emitter/receiver elements which extend along at least two different directions (X, Y), each set of ultrasonic wave emitter/receiver elements (3) comprises at least one alignment of elements ultrasonic wave transmitters/receivers, it is characterized in that at least one ultrasonic wave transmitter/receiver element is arranged at the intersection of the two directions. The position of a transmitter/receiver element in the center or at the intersection of the two directions makes it possible, in the case of a spot weld, to detect the presence of a shrinkage in the center of the spot weld.
