- What it is about:
- Non-destructive testing technique that uses electromagnetic fields to detect surface and subsurface discontinuities in conductive materials.
- How it is done:
- An alternating magnetic field induces an electrical current in the material. Discontinuities in the material disrupt the Eddy currents, which are detected by sensors.
- Where it applies:
- In the aerospace, automotive, railway, and pipeline manufacturing industries to detect cracks, fissures, and other defects in metallic materials.
