Abstract:
An arrangement for testing an elongated body 1 or a welded and bonded joint in the body for faults 60 has a device 4, 5 for production of an eddy current in the elongated body 1 or its welded and bonded joint. At least one magnetic field sensor 7 for sensing the magnetic field is provided on the elongated body 1 or the welded and bonded joint. The dimensions of the at least one magnetic field sensor 7 are equal to or less than the fault 60 to be investigated.
