Eddy Current Testing (ET) is an electromagnetic non-destructive testing method that detects surface and near-surface discontinuities by measuring changes in the eddy currents induced in a conductive material. Flaws are sensed as impedance changes.
It requires no couplant, can be applied through thin coatings and delivers high speed and sensitivity, particularly 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 ET (Eddy Current Testing)?
- No couplant — clean and fast
- Inspects through thin coatings
- Excellent for tube bundles
- High throughput screening
