NDT Techniques that use Magnetism

Within the realm of Non-Destructive Testing (NDT), various techniques are employed to inspect materials and structures for flaws and defects without causing damage. EMWorks specializes in NDT techniques that utilize magnetism, offering cutting-edge solutions for a range of critical applications. These magnetic NDT techniques include:
Magnetic Particle Testing (MT)

  • Magnetic Particle Testing, often abbreviated as MT, is a widely used NDT technique. It's particularly effective for detecting surface and near-surface defects in ferromagnetic materials.

  • The process involves magnetizing the material under inspection using a magnetic field. Then, fine magnetic particles (usually iron filings) are applied to the surface.

  • These magnetic particles are attracted to areas with magnetic flux leakage, indicating the presence of defects like cracks or discontinuities.

  • MT is commonly used in industries such as aerospace, automotive, and manufacturing for its ability to quickly reveal flaws in materials, making it a cost-effective inspection method.

Eddy Current Testing (ET)
  • Eddy Current Testing, or ET, is a versatile NDT method that relies on the induction of eddy currents in conductive materials.

  • A coil carrying an alternating current is placed near the material being inspected. Eddy currents are induced in the material, which in turn generate their own magnetic fields.

  • Variations in the eddy currents are detected and analyzed to identify surface and subsurface defects, measure material thickness, and assess the conductivity of materials.

  • ET is widely used in the aerospace, automotive, and manufacturing industries for inspecting critical components like aircraft engine parts and automotive brake components.

Magnetic Flux Leakage (MFL)

  • Magnetic Flux Leakage (MFL) is a specialized NDT technique primarily used for inspecting pipelines, storage tanks, and other ferromagnetic structures.

  • In MFL, a magnetic field is applied to the material under inspection, magnetizing it.

  • Any discontinuities or defects in the material, such as corrosion or cracks, disrupt the magnetic field, causing leakage.

  • Sensors are used to detect these disruptions, allowing for the precise identification and measurement of defects.

  • MFL is vital in the oil and gas industry for inspecting pipelines, ensuring their structural integrity and preventing leaks.

Remote Field Testing (RFT)

  • Remote Field Testing (RFT) is an extension of eddy current testing, designed for inspecting ferromagnetic tubing or pipes, particularly in situations where access is limited.

  • It is highly effective at detecting defects in heat exchanger tubes, boiler tubes, and other components that are challenging to access directly.

  • RFT employs specialized probes that generate remote field eddy currents, allowing for the assessment of wall thickness and the detection of flaws.

  • This technique is crucial in industries like power generation, where the integrity of heat exchanger tubes is essential for efficient operations.

Alternating Current Field Measurement (ACFM)

  • Alternating Current Field Measurement (ACFM) is a precise NDT technique used to detect and size surface-breaking cracks and defects in conductive materials.

  • ACFM utilizes alternating current to induce eddy currents in the material being inspected, and a probe measures the resulting magnetic fields.

  • It is highly sensitive and capable of providing accurate defect sizing information, making it valuable for applications where precision is crucial, such as offshore oil and gas infrastructure inspections.

Pulsed Eddy Current Testing (PECT)

  • Pulsed Eddy Current Testing (PECT) is employed for assessing the thickness and integrity of metallic components, such as pipes, storage tanks, and pressure vessels.

  • This technique utilizes pulsed eddy currents, where short-duration electromagnetic pulses are used to induce eddy currents in the material.

  • PECT is particularly useful for corrosion assessment, as it can penetrate through non-conductive coatings to inspect the underlying metal, making it vital in industries like oil and gas for asset integrity management.

These NDT techniques provide invaluable tools for inspecting materials, ensuring safety, and maintaining the integrity of critical components across various industries. Their precise and non-destructive nature makes them essential for quality control and defect detection in modern applications.
