Abstract

Appareil pour la détection et la localisation in situ des défauts dans les soudures. L'appareil permet de détecter in situ et de localiser les défauts de soudure; on isole les émissions acoustiques provenant d'un défaut des autres émissions acoustiques, en distinguant les émissions provenant de la zone de soudure qui tombent à l'intérieur d'une bande prédéterminée de fréquences, et on localise le défaut en déterminant le temps requis pour permettre à ces émissions d'arriver à deux points prédéterminés mutuellement espacés. Applicable notamment aux soudures à plusieurs passes.
