  • Method for automated measurement of the residual magnetic field strength of magnetized ferromagnetic workpieces
    Patent number: 8941376
    Abstract: The invention relates to a method for the automated measurement of the residual magnetic field strength of magnetized ferromagnetic workpieces, especially steel tubes, the residual magnetic field exiting the face of the tube end being measured by means of a measuring probe. Instead of directly measuring the residual field strength on the face, the curve of at least one magnetic field component is measured on the outer surface of the tube at least in the region of the tube ends and beyond the tube ends and the residual field strength on the face is inferred on the basis of the previously determined correlations between the residual field strength measured on the face and on the tube surface.
