摘　　要：在金属工件的无损检测之中磁粉探伤是非常关键的一种检测方式,一般被运用到工件表面或者近表面的缺陷及裂纹检测上。为了防止在给金属件进行探伤的时候发生结果不精准或者是漏检的情况,就必须要定期对该设备实施校准。本文就将重点通过磁轭式的探伤机的校准及金属构件磁粉探伤机的校准,对其磁化电流的不确定度进行分析评定,以供参考。Magnetic particle testing is a very important testing method in the non-destructive testing of metal workpieces,which is generally applied to the detection of defects and cracks on or near the surface of workpieces.In order to prevent inaccurate or missed results when testing metal parts,the equipment must be calibrated regularly.This paper focuses on the analysis and evaluation of the uncertainty of magnetizing current through the calibration of yoke type flaw detector and metal component magnetic particle flaw detector for reference.
