Abstract
This paper presents a measurement technology to detect surface and subsurface flaws in heavy steel plates. This method is related to a magnetic flux leakage (MFL) widely used in the inspection of flaws in pipeline and storage tank. The MFL measuring system including element technologies such as multi-channel magnetic sensors and high-speed signal processor has been developed for use in the manufacturing process. Pilot tests were conducted for detecting surface and subsurface flaws, and detecting material property deviations. Interesting results were obtained, and how to utilize them in the future will be discussed.
