Abstract

L'invention concerne un procédé permettant de marquer des points défectueux sur des pièces chaudes à contrôler, au cours duquel, après réception de l'instruction de marquage en provenance d'un dispositif fixe, un agent de marquage est impliqué sur la surface de la pièce au moyen d'air comprimé, au moins pendant la durée du signal indicateur. L'agent de marquage commence à s'écouler sans obstacle et de manière ininterrompue vers la zone de décharge et, simultanément, l'alimentation en air sous pression, qui doit être sufissante, le fonctionnement de toutes les connexions électriques y compris et tous les circuits électriques, lequel doit être parfait, et le niveau d'agent de marquage dont les dispositifs sont surveillés. L'invention concerne également un dispositif permettant de mettre en oeuvre ledit procédé.
