    Magnetic particle testing (MT) and Penetrant Testing (PT) are widely used for surface inspection of structures. However, they require time-consuming pretreatment work such as coating removal and liquid-proofing, and their detectability may be insufficient depending on the defect type and surface condition, so there is an issue of requiring shorter working time and higher detectability. To address this issue, Mitsubishi Heavy Industries, Ltd. (MHI) has developed an eddy current testing (ECT) service in lieu of MT and PT. This service improves the reliability of equipment and reduces inspection time and costs, thereby contributing to meeting the needs of customers.
