| Abstract: | It is difficult to detect defects quantitatively by NDT. To solve this problem, the paper presents a theory and a method based on pattern recognition to analyze the magnetic flux leakage signal for defects quantitatively. Many experiments of detecting works with man - made and natural defects have been conducted. The result obtained is satisfactory. |
