Abstract

L'invention se rapporte au contrôle des produits métallurgiques. Dans ce procédé et ce dispositif, on se sert du bras 1 qui porte les outils d'ébavurage intérieur du cordon de soudure pour monter les sondes 2 et 5, sensibles aux champs magnétiques, utilisées pour la détection magnétique des defauts de la région du joint soudé. Les générateurs de champs magnétiques 4 et 6 peuvent être indépendants de l'équipement de soudage ou au contraire constitués par des éléments de cet équipement L'invention s'applique notamment à la détection des défauts de soudure des tubes soudés à joint longitudinal ou hélicoïdal.
