Section: abstract

A detection and inspection of cracks (135) on the internal surface of the adapter (2) is carried out, at least in a zone close to the weld for fastening the adapter (2), using remote inspection operations comprising at least one dye penetration inspection with remote borescope examination of the cracks (135) revealed by the dye penetration. At least one excavation cavity (136) is made by machining to a specified depth of the internal surface of the adapter (2) having a crack (135). As a function of the result of the dye penetration inspection, the zone is or is not built back up after excavation. The device comprises an assembly for moving a rod in translation and in rotation inside the adapter. Brushing, cleaning or sprinkling devices, a device for moving a borescope support inside the adapter and tooling for machining the internal surface of the adapter may be fastened to the end of the rod.
