Abstract
L'invention concerne la détection précoce de la formation de fissures dans des éléments de construction. Elle se rapporte à un procédé qui comprend la formation d'une cavité dans des éléments de construction, par exemple au voisinage d'une soudure, cette cavité étant reliée par une canalisation 9 à une source de vide par exemple. Si une fissure 15 se propage dans l'élément de construction, le vide de la cavité est affecté et est détecté et des mesures correctrices peuvent être donc être prises. Application au contrôle des soudures des plates-formes de forage en mer.
