| Abstract: | By studying the magnetic nondestructive testing technologies home and abroad,the scheme and testing system for steel ball surface or near surface flaws was put forward, by which the balls were magnetized by the magnetic field of the earth. It solved the problem of complicated magnetization procedure in magnetic inspection, and offered the possibility of low price, high sensitivity and micro magnetic testing. |
