    • The invention pertains to a process and device for the ultrasonic examination of a disk element (2) shrunk onto a shaft (1) in the region of the shrink seat (3) and adjacent shrink-affected zone. The disk element (2) in cross-section has lateral faces (4, 5) which taper radially outwards from the shrink seat. The contours of the disk element (2) are scanned and thus its geometry is deduced. A geometrical reflection surface is determined. In accordance with predetermined test techniques, test parameters and positions are determined from the disk element geometry and ultrasonic test heads (9, 10) are coupled to the lateral faces (4, 5) using the test parameters thus determined to travel along the defined test paths. The associated device has a geometry recognition device which captures the geometry of the disk element (2) before the actual test. The invention facilitates time-saving examination of turbine wheel disks without the need to know their geometry beforehand.

Date Apr. 10, 1997Method and apparatus for ultrasound testing of disc bodies which are shrunk onto shafts and have an unknown contour. The invention relates to a method and an apparatus for ultrasound testing of a disc body (2), which is shrunk onto a shaft (1), in the region of the shrink seating (3) and of the adjacent shrinkage influence zone, the disc body (2) having side pieces (4, 5) which taper radially outwards from the shrink seating in cross-section. The contour of the disc body (2) is scanned and its geometry is derived in this way. A geometric reflection surface is determined. Test parameters and test positions are determined from the disc body geometry in accordance with a predetermined test technique, and ultrasound test heads (9, 10) are coupled, using the determined test parameters, to the side pieces (4, 5) in order to cover the determined test paths. The associated apparatus has a geometry identification device which detects the geometry of the disc body (2) before the actual test procedure. The invention makes it possible to test turbine discs in a time-saving manner, without it being necessary to known their geometry before the test.
