抄録

To enhance a wobbling noise reduction feature and 2D flaw resolution characteristic for tube eddy current ISI, the authors developed a new multi-bank multi-coil probe using uniform eddy current. The new probe has a large/long solenoid coil for excitation and small pancake pickup coils. The excitation coil induces a uniform eddy current that flows in a circumferential direction in the tube wall and the pickup coils are positioned in the area of the uniform eddy current. The self-differential feature makes the probe self-nulling and free of wobbing noise. The authors also developed a multi-bank probe that is constructed from four banks of coil. Each bank has eight pickup coils. All signals generated by the 32 pickup coils are integrated into a 2D defect signal just like a signal by an ordinary multi-coil probe. The multi-bank method allows easy establishment of a higher resolution multi-coil. The newly developed probe makes the tube test reliable with less noise and more information than a conventional multi-coil probe.
