<p>The subject of the invention is a method for checking the contact between two metal sheets placed edge to edge, in which an ultrasound signal propagating in one of the two metal sheets (1, 2) is emitted, the said ultrasound signal passing through the joint plane (3) of the said metal sheets over its entire height and propagating through the second metal sheet (2), the said ultrasound signal is picked up in the second metal sheet (2) and the quality of the contact of the metal sheets (1, 2) at the joint plane (3) is determined by comparing the said ultrasound signal picked up with respect to the said ultrasound signal emitted. A further subject of the invention is a checking device for implementing this method. <IMAGE></p> |
