Eddy Current Testing (ECT)
- High Frequency Eddy Current (HFEC)
- Low Frequency Eddy Current (LFEC)
- Bolt Hole
- Conductivity (Digital, Direct Readout)
- Coating thickness (conductive and non-conductive)
- Material Sorting (Alloy, Heat Treat, Conductivity)
Eddy Current Testing (ECT) is an electromagnetic based Non-Destructive testing method that makes use of electromagnetic induction to detect and characterize surface and sub-surface discontinuities in electrically conductive materials that related to either a change in electrical conductivity or magnetic permeability. This is done using specialized instruments operated by a highly trained staff that have the additional support of multiple subject matter experts.
Eddy Current is commonly utilized in the aerospace industry for detection of cracks and other linear-type discontinuities. HFEC is typically used to detect surface defects, while LFEC can be used to detect subsurface defects or defects in internal structures such as aircraft skin repair doublers. Aircraft wheels and brakes can be inspected for suspected heat damage via a conductivity test.
Advantages of Eddy Current testing are:
- Instantaneous results
- Extremely portable
- No hazardous chemicals required
- No harmful effects or byproducts to personnel or the environment
- Little to no consumable materials required
- Not injurious to parts or materials to be inspected
- Wide range of materials that can be inspected
- Inspection through nonconductive coatings such as paint/primer
