Abstract

L'invention concerne un procédé et un système d'inspection ultrasonore, qui se rapportent au domaine technique de l'inspection ultrasonore. Le procédé d'inspection ultrasonore consiste en : le marquage d'une première zone sur une entité de pièce, la première zone étant une zone qui ne peut pas être inspectée au moyen d'un dispositif de balayage automatique ou une zone qui doit être balayée dans un second mode de balayage, et la zone qui doit être balayée dans le second mode de balayage recouvrant la zone qui ne peut pas être inspectée au moyen du dispositif de balayage automatique ; et la réalisation d'un balayage automatique sur une zone de l'entité de pièce qui peut être inspectée au moyen d'un balayage automatique, et le balayage de la première zone dans le second mode de balayage, achevant ainsi l'inspection de balayage pour l'entité de pièce entière. Par conséquent, lorsqu'une zone de balayage automatique existante est limitée, une inspection automatique ultrasonore pour une pièce surdimensionnée peut être réalisée, il n'est pas nécessaire d'inspecter manuellement la totalité de la pièce, et il n'est également pas nécessaire d'adapter un dispositif de balayage automatique plus grand, ce qui permet de réduire les coûts et d'obtenir une efficacité élevée.
