Eddy Current Testing (ECT)

Principle:

ECT inspection is one of a number of NDT methods employing electromagnetism in conductive materials for tasks such as the detection of surface and near surface flaws and determining material properties.

Applications:

Aerospace Industry:

  • ECT is used for the testing of aircraft components such as turbine blades, engine parts, and landing gear.
  • It can detect surface cracks, corrosion, and flaws in critical components, ensuring the safety and reliability of aircraft.

Automotive Industry:

  • ECT is employed for quality control and testing of automotive parts like engine blocks, crankshafts, and suspension components.
  • It can detect defects such as surface cracks, porosity, and heat treatment irregularities.

Power Generation:

  • ECT is utilized in the testing of power plant components, including steam turbine blades, generator rotors, and heat exchanger tubes.
  • It helps identify surface cracks, erosion, and other defects that may affect the efficiency and reliability of power generation equipment.

Tube and Pipe Inspection:

  • ECT is commonly used to test tubes and pipes in industries like oil and gas, petrochemical, and heat exchangers.
  • It can detect wall thickness variations, cracks, corrosion, and other defects that may compromise the integrity of the tubes or pipes.
