Abstract

Measurement method of density of magnetic flow from the surface of metals that dispose magnetic properties, by the use of Hall sensor (10), aiming at the determination of the areas with non uniform distribution of components or structural imperfections. Furthermore, use of the method for detection of bodies with magnetic properties in non magnetic materials. The scanning of the metal under examination is made by articulated machine (figure 4) that is controlled by a closed loop control system and the distance of the sensor from the surface of the metal and its inclination as to the level of the metal is checked with optical sensors (12. 1 12. 2 12. 3).
