Nondestructive testing——Eddy current testing
Eddy current testing is suitable for inspection of defects generally not larger than 6 ~ 7MM deep below the surface. Eddy current testing is divided into two methods: the method of placing coil and the method of passing through coil. : when the specimen is placed near the coil of alternating current on, into the alternating magnetic field of the specimens can be induced in the specimen perpendicular to the direction of the magnetic field phase, the shape of vortex flow of current (eddy current), eddy current will produce a and motivation in the opposite direction from the magnetic field magnetic field, reduce part of the original magnetic field in coil, thus cause the coil impedance change. If the casting defects in the surface, the electrical characteristics of the eddy current distortion happens, to detect the presence of defects, the main disadvantage of eddy current testing is not intuitive display detected defect size and shape, normally only determine the defect on the surface of the position and depth, and it small openings on the workpiece surface defect detection sensitivity than penetrant testing.
