Abstract

L'invention concerne les contrôles non destructifs effectués à l'aide de dispositifs électromagnétiques à ultrasons. Un tel dispositif comprend un électro-aimant 1 à 4 produisant un champ magnétique constant dans le spécimen 5, un enroulement d'émission 8 et un enroulement de réception 8 montés à proximité des pôles de l'aimant et bobinés de manière à être sensiblement plats et séparés par une certaine distance latérale L'invention est applicable au contrôle des matériaux conducteurs de l'électricité, notamment des métaux, se présentant sous la forme de tiges, de barres ou de tubes.
