摘要： PROBLEM TO BE SOLVED: To provide an inspection apparatus which takes advantage of the characteristics of each of an eddy current testing (ECT)-based flaw detection apparatus and an imaging-based flaw detection apparatus in an inspection system for detecting flaws on a metal bar. SOLUTION: The ECT-based flaw detection apparatus 20 and the imaging-based flaw detection apparatus 30 are disposed along a movement path in a predetermined positional relationship with each other, for example, keeping a predetermined fixed offset distance between them. A synchronization mechanism 46 synchronizes output data series from the two flaw detection apparatuses based on the predetermined relationship so as to align the data series depending on an axial position on the metal bar 11. A processing unit 40 is configured to process the synchronized data series for the detection of flaws, and the information on these flaws is also synchronized (axial direction). The synchronization permits a variety of cross-referencing operations, such as flaw verification on the presence of flaws 14 and augmenting imaging-based flaws with flaw depth information from the ECT-based apparatus.
