Advantages and disadvantages of eddy current testing
Eddy Current testing machine range of applications: 1,Specimen geometry: shape, size, thickness of the like. 2,Conductivity: chemical composition, hardness, stress, temperature, heat treatment and so on. 3,Discontinuous defect: cracks, inclusions, porosity, delamination, uneven material. 4,Permeability: ferromagnetic materials heat treatment, chemical composition, stress, temperature and the like. Eddy Current testing machine advantages: First, for the detection of metal pipes, rods, wire and plate, without touching, does not require a coupling medium, so that a high detection speed, easy to automate the detection, especially for online inspection P; followed by high sensitivity for the detection of defects, and within a certain range a good linear indication of the size of the different defects can be evaluated, so can be used as quality management and control, such as cracks, material, size, shape and electrical conductivity and permeability; the third, sinc...
