ABSTRACT:
An array for non-destructive material testing of cylindrical workpieces such as pipes or ends thereof by means of leakage-flux measurement and if necessary electrodynamic ultrasonic excitation is proposed. A leakage-flux measuring head (56) used for leakage-flux measurement comprises at least two Hall probes (80) disposed along a line parallel and/or vertical to the magnetic field generated by a magnet (10) and forming at least one Hall probe line. In addition, the leakage-flux measuring head has at least two sliding blocks (94, 96, 98, 100) spaced apart and supportable on the workpiece, between which the Hall probes are disposed. The leakage-flux measuring head is also provided with a protective plate covering the faces of the Hall probes on the workpiece side.
