Vue d’ensemble

Inspection des soudures — Scanner motorisé à un axe

Le WeldROVER^™ est conçu pour les clients ayant besoin d’une inspection offrant plus de stabilité que celle fournie par les scanners manuels, mais qui cherchent une solution plus abordable que les systèmes par discrimination de zones à production élevée généralement utilisés pour les projets de construction de pipeline en mer.

Le WeldROVER est un scanner motorisé à un axe codé simple de qualité industrielle qui permet une acquisition de données mécanisée et entièrement automatisée. Il est conçu pour effectuer des inspections par ultrasons multiéléments rapides et efficaces des soudures circonférentielles ou longitudinales sur les tuyaux ou les réservoirs ferromagnétiques. Son utilisation nécessite peu de formation et peu de temps de mise en place. Le scanner supporte jusqu’à six sondes pour l’inspection par ultrasons multiéléments, TOFD et ultrasons conventionnels.

Très facile à utiliser, le scanner WeldROVER fonctionne à l’aide d’une télécommande à deux boutons à vitesse variable. Le scanner peut se connecter directement aux appareils de recherche de défauts de la gamme OmniScan^® et FOCUS sans qu’il soit requis d’utiliser un logiciel, un contrôleur d’exécution ou des configurations complexes. L’indicateur laser aide l’opérateur à régler manuellement la direction du scanner à l’aide du levier de direction. Cet outil assure une acquisition de données précise, sans qu’il soit requis d’utiliser des bandes de guidage ou un système de repérage ou de direction motorisée complexes. Il s’agit de la solution parfaite pour les entreprises offrant des services d’inspection par ultrasons multiéléments automatique et mécanisée. Pour ceux qui ont déjà complété la formation OmniScan de base, moins d’une heure de formation est nécessaire.
