Calibration Standard for Array Eddy Current Testing Probe

摘要

The present invention relates to a calibration test piece of an array type eddy current inspection probe. In particular, an array type eddy current inspection device used to detect surface defects such as pipe welds, turbine blades, pump impellers, and valve disks, which are main components of a power plant, can be used for a short time. It relates to a calibration specimen that can be calibrated inside.;More specifically, the artificial defects constituting the calibration test piece are arranged in various directions according to the directions so as to be suitable for the array type eddy current test probe, so that the calibration of the eddy current test device, which is essential before the eddy current test, can be efficiently performed in a short time. The calibration test piece of the array type eddy current test probe can be used.;Eddy current inspection, transducer, calibration test piece
