概要
The technique of obtaining shape of inclined defect at heat affected zon e for welded specimen of high chromium steel was proposed. In this techn ique, magnetic flux leakage measurement and the inverse analysis using s ingular value decomposition were used. Suitable defect shape was obtained from the magnetic flux density distribution under the high magnetic fiel d without being subject to the influence of a welding part. Under the lo w magnetic field, suitable defect shape was obtained by subtracting the magnetic field of welding part from measured magnetic flux distribution.
