High speed ultrasonic axle inspection using a phased array with an electronically rotated beam
- The ultrasonic testing of the railway axes with a hollow drilling can be realized from the inside of the drill hole without demounting the axes and without dismantling the wheels and the brake discs. Flaws in the outer surface of the hollow shafts, whose orientation lies in the radial-radial plane have to be detected. Common testing systems use scanning in the circumferential direction by mechanical rotation of the probe system in the drilling. The presented phased array probe system carries out the rotation scan by electronically steering of the sound field only. Thereby manipulation of the probe inside the drilling becomes more simple and the inspection time can be shortened significantly. The beam will additionally be focused in the plane vertical to the specimen axis to optimize sound field parameters to different axle geometries.
