Eddy Current Testing (ET) induces circulating currents in a conductive part; flaws disturb those currents and are detected as impedance changes. It needs no couplant, works through thin coatings and is extremely fast for surface crack screening and heat-exchanger tube inspection.
Typical Applications
- Heat-exchanger and condenser tube inspection
- Surface crack detection on conductive alloys
- Coating and conductivity verification
- Weld toe inspection on painted structures
Why TESKO NDT
- No couplant — clean and fast
- Inspects through thin coatings
- Excellent for tube bundles
- High throughput screening
