Magnetic flaw detector for tubular goods |
摘要 |
A magnetic flaw detector for use in small-diameter tubular goods employs a second magnetic field to confine a first magnetic field to reside within a desired volumetric region in the wall of a specimen under test. A flux leakage detector and a variable reluctance sensor provide means for detecting and discriminating between defects on the inner and outer surfaces of the specimen. |
