Abstract :
The method of eddy-current flaw detection based on the combined multi-sector transducer with a magnetic field of different frequencies is observed. Technical implementation of a method for flaw detection of bars and pipes in the conditions of the considerable transverse displacements of controllable articles and inhomogeneity of magnetic and electrical properties of a material is presented.
