In this course students deepen their understanding of electromagnetic principles, including impedance plane analysis, phase relationships, and advanced eddy current techniques. The course covers the selection and configuration of probes, coils, and frequencies to detect and evaluate surface and subsurface defects in various materials and geometries. Emphasis is placed on signal interpretation, distinguishing between defect signals and material variations, and performing detailed evaluations in accordance with applicable standards.
This 40-hour course meets or exceeds the instruction outline and criteria specified in NAS-410, ASNT Recommended Practices SNT-TC-1A, ANSI/ASNT CP-189 and ASNT Standard Topical Outlines for Qualification of Nondestructive Testing Personnel (ANSI/ASNT CP-105).
