Abstract
This paper aimed at the problem that it is impossible to evaluate the depths of the surface-breaking defect of austenitic stainless steel pressure pipes using the Magnetic Particle Testing(MT) and Penetration Testing(PT) methods. A quantitative method for measuring the depths of the surface-breaking defect of austenitic stainless steel pressure pipes based on eddy current array testing (ECAT) was proposed. According to the imaging features of defective ECAT correlation, by analyzing the change trend of the color, impedance amplitude and impedance phase of the C scanning, the corresponding relationship between the depth of the defect can be established, and finally, the effective evaluation of the depth of the opening defect on the surface of the material can be realized. Simulation and experimental results verify the effectiveness and reliability of the proposed method.
