Detection of flaws in metallic structures (ferromagnetic and non-ferromagnetic):
- production of metals (material and structural defects, discontinuities )
- process of manufacturing metal items (quality control)
- metal items being operated
- electrical conductivities of non-ferromagnetic metals
- thickness of metallic coatings and non-metallic coatings on conductive materials
- orientation and scope of the flaws
Classification of metals according to:
- chemical components
- identification of alloy
- effects of the heat treatment
- High sensitivity to microscopic flaws.
- No possible harm to the surface being inspected.
- No surface preparation needed (eg. no paint removal).
- No danger from radiation.
- No couplant needed.
- High inspection speeds.
- Low costs of inspection.
- Underwater probe available.
- Compatible with PCs (data sending and processing).
- Environment-friendly testing method.
- Possibility of application in the automated quality control systems.
