• Non-Destructive Testing: The test causes no damage to the material, allowing it to remain in use.
• Fast and Effective: Enables high-speed testing and rapid scanning of large areas.
• Detection of Surface and Sub-surface Defects: Detects small defects on the surface and just below the surface with high sensitivity.
• Portable Use: Testing equipment is generally portable and can be easily used in a wide range of environments.
• Applicable to Various Materials: Can be used on many different types of materials, such as aluminum, copper, and steel.
• High Sensitivity: Offers high accuracy in detecting even minute defects.

• Requirement for Surface Cleaning: The surface to be tested must be clean; otherwise, test results may be misleading.
• Detection of Surface Defects Only: Eddy currents can only detect defects on the surface or just below the surface. Other methods may be required for deep-seated defects.
• Requirement for Electrical Conductivity: It is applicable only to electrically conductive materials; it cannot be used on non-conductive materials.
• High Equipment Costs: The devices and testing kits can be expensive in some cases.

Techniques:

• Surface Scanning: The most common technique used to detect surface defects.
• Depth Scanning: A technique used to detect defects located beneath the material's surface.
• Internal Defect Detection: Advanced techniques used to detect corrosion, cracks, or other flaws within the internal structure of metal parts.

Eddy current testing is widely used in the following areas, particularly to detect surface and near-surface defects:

• Automotive Industry: Detecting surface defects in metal parts, chassis, engine components, and other structures.
• Aerospace Industry: Inspecting for cracks and corrosion on the surfaces of critical components such as airframes, wings, and engines.
• Energy Sector: Detecting corrosion, cracks, and other defects in pipelines, tanks, and other equipment at nuclear and thermal power plants.
• Oil and Gas Industry: Inspecting for internal and surface defects in pipelines, tanks, and other materials.
• Construction and Infrastructure: Detecting cracks and deterioration on the surfaces of reinforced concrete and metal structures.
• Electronics and Home Appliance Industry: Inspecting electrical circuits, solder joints, and other critical electronic components.

Eddy Current Testing (ECT) is a non-destructive testing method used to detect subsurface defects in electrically conductive materials. In this method, an alternating magnetic field is applied to the material's surface, generating eddy currents. Defects within the material are detected by the changes they cause in the density and direction of these eddy currents. Consequently, surface cracks, holes, corrosion, and other defects can be easily identified.

The primary standards adopted for eddy current testing are as follows:

• ISO 15549: An international standard providing information on the general methods and applications of eddy current testing.
• ASTM E2871: Establishes standards for testing electrically conductive materials using eddy currents.
• EN 1711: A European standard that defines requirements for the industrial application of eddy current testing.
• ASME Section V: A standard published by the American Society of Mechanical Engineers (ASME) that outlines specific requirements for eddy current testing.

Eddy current inspection is performed through the following steps:

1. Preparation and Cleaning: The surface of the material to be tested is cleaned. Oil, dirt, and rust on the surface can adversely affect test results; therefore, a clean surface is ensured.
2. Probe Placement: The eddy current probe (sensor) is placed on the surface of the material to be tested. The probe directs a magnetic field to induce an electrical current within the material.
3. Applying Alternating Current: Alternating current (AC) is applied to the material via the probe. This current interacts with the material's electrical conductivity and generates eddy currents within the material.
4. Measuring Eddy Currents: Any defect in the material (crack, corrosion, hole, etc.) alters the flow of the eddy currents. This change is transmitted to the probe's detector.
5. Data Analysis and Results: The obtained data is analyzed using a device or software. Changes in the eddy currents indicate the location and size of defects within the material.
6. Reporting: The test results are documented and presented to the relevant parties.
