A method for the inspection of screws with an eddy current test probe including an insulating material body having a linear contact surface and at least one coil disposed in the body, includes orienting the coil transverse to threads of a reactor pressure vessel setscrew to be inspected, feeding high-frequency alternative current through the at least one coil, generating a coil field covering at least two threads, and guiding the linear contact surface along the threads, and a device for carrying out the method.

Method and eddy current test probe for the inspection of screws for

Analysis manipulator for non-destructive material testing, including a support device having a mounting flange, a precision coordinate-moving mechanism having at least two guide frames each including coordinate drives in the form of straight guides and a drive having a spindle and a nut being movable by the spindle along the straight guides, the guide frames including a first lower guide frame having a mounting flange being mountable to the mounting flange of the support device, a second guide frame being movable by the coordinate drive of the first guide frame in a first given coordinate direction, and a testing head mount being movable by the coordinate drive of the second guide frame in a second given coordinate direction, and a method for the coordinate control of the analysis manipulator.
