本文介绍检验实心圆柱形试样、以椭圆法工作的渦流检查法。着重于试样直径、缺陷、组织性能的变化对线圈阻抗的影响,从而用示波器营光屏上的椭圆形状及大小辨别试样直径、缺陷、组织及性能的变化。一、概述近年来,在无损检验领域中出现了一个新的、有广阔发展前途的方法——渦流检验法。渦流检验能有许多其它检验法所不具备的
This article describes the eddy current test that tests solid cylindrical specimens in an elliptical manner. Focus on the sample diameter, defects, changes in tissue properties on the coil impedance, and thus use the oscilloscope screen elliptical shape and size of the sample to identify the diameter, defects, changes in the organization and performance. I. Overview In recent years, in the field of nondestructive testing there has been a new, promising broad method - eddy current test. Eddy current test can have many other tests do not have
