Surface Crack Detection using
Eddy Current Vs Magnetic Particle testing
Crack detection methods on ferrous materials like iron, nickel, and cobalt-based alloys are simple. Magnetic particle inspection effectively detects cracks in all ferromagnetic materials. For non-ferrous metals, Eddy current testing emerges as a valuable NDT technique. Detects cracks up to 3-5mm based on frequency, conductivity, permeability, of material.
Eddy current testing can be performed without the need for direct contact. Crack detectors taken precedence in various fields. Rapidly replacing magnetic particle testing where precision, speed are of utmost importance. Consider railway track inspection at steel plants. Eddy current machines adeptly uncover cracks. The non-contact nature, swift inspections, surpassing the capabilities of ultrasonic testing without requiring couplant.
Though magnetic particle equipment costs are comparatively less, the cost of eddy current inspection is minimal. Possibility for fully automating the process has direct effect on productivity, economy. Eddy current testing offers speeds that surpasses other NDT techniques. Thickness gauging of pipes, tubes, while in hot condition are possible using non-contact probes. The only limiting factor is higher level of operator skill for performing the test, evaluation of signals.
Overall, in summary, MPT testing suits for ferromagnetic materials much better. For non-ferrous, we recommend eddy current testing for speed and accuracy combined with economy. We offer finest NDT solutions on both MPT and ECT from our NABL accredited labs in Bangalore. Contact us with your challenge today.
Depth of Penetration in Eddy Current Inspection
Similar to Ultrasonic Testing (UT), our method offers accurate crack depth detection. The depth of crack identification in Eddy Current relies on material conductivity, frequency. Higher material conductivity or higher permeability leads to shallower penetration. Mainly limiting currents to surfaces. Less conductive materials allow the detection of deeper cracks. The depth of detection reaches three times the skin depth.
Typically eddy currents penetrate up to a maximum depth of 3-5mm. For ferrous metals depth of penetration is quite less. May be not even 1mm. In practice, to enhance penetration in highly conductive, permeable materials we use lower frequencies. Our ASNT Level III eddy current experts can analyse the objective of your testing, provide appropriate solution.

Facility for Solutions to Challenging Applications.
Material Sorting based on Hardness, Heat treatment
Material mix-up is a frequent challenge arising from the diverse range of machined, heat-treated materials. When mix-ups involve variations in chemical composition, traditional methods like wet analysis, PMI are time-consuming, cost-intensive. Here is the solution. Eddy Current offers effective means of sorting based on chemistry, hardness.
Components with varying designs, chemistries, heat treatments, and properties are processed. One of the most prevalent issue is the inadvertent mix-up of different material grades. Mix-ups might encompass variation in chemistry, mechanical properties, or metallurgical structures. Eddy Current sorting emerges as the cost-effective, time-efficient solution. This method is progressively gaining traction in modern manufacturing.
Portable, stationary Eddy Current machines are available, tailored to the sorting volume, speed requirements. Whether it’s manual sorting or automation, machines excel in delivering precise results, Trinity NDT – Labs in Bangalore, provide material sorting solutions, catering to your specific needs.

Know more about Eddy Current Testing
Principle
When a test conducting object is brought close to the AC field of test coil, flux causes electrons to circulate in a swirling eddy-like pattern in the object; thus the term ‘eddy currents’. In other words, eddy current behavior depends on the properties of both the flux and the object itself. Therefore, eddy currents are circular AC currents caused by a varying magnetic field. It works on the principle of ‘EM induction’. If there is a change in current flow path, that will provide an indication on screen.
How Eddy Current Testing works?
In Eddy current testing, the test component is placed in a varying magnetic field of a coil carrying Alternating Current(AC). The AC magnetic field (primary) induces eddy currents in the test component. The eddy currents, in turn, produce an secondary magnetic field. As per Lenz’s law, this secondary magnetic field opposes the primary magnetic field which caused it to produce. Finally, by scanning and measuring the changes in impedance in an area of test object, cracks and material properties can be evaluated.
Limitations
Eddy Current testing is only suitable for electrically conducting materials such as Aluminium, Steel, Brass, Bronze, Gold etc., Testing is not possible on wood, plastics, glass and other non conducting materials. It is one of the major limitation in this NDT method.
Also, Alternating currents (AC) can only be used to generate and perform inspection. Because, to generate eddy currents, changing magnetic field is needed.
Maximum Depth of Penetration
Eddy current has skin effect, there the maximum depth of penetration is limited to three skin depths only. Beyond that current density deminishes rapidly thus reducing crack detectability exponentially. Can detect flaws up to maximum 3-4mm based on conductivity and permeability of the material.
Differences between Ultrasonic and Eddy Current Testing
- Ultrasonic Testing (UT) and Eddy Current (ET) are two prevalent methods. Each utilizing distinct physical principles. UT relies on high frequency sound waves, while ET employs electromagnetic waves.
- In terms of frequencies, UT operates within the range of 20kHz to 25MHz. ET utilizes a frequency spectrum spanning from 50Hz up to 15MHz.
- A significant divergence lies in the use of couplant. UT mandates use of a coupling medium. ET does not require a couplant.
- Contact is essential in UT. ET operates without the need for physical contact.
- Comparing inspection speeds, ET takes the lead with significantly faster inspection rates compared to UT.
- UT specializes in identifying internal flaws, while ET excels in detecting surface, subsurface flaws.
- Ultrasonic can be applied to any object that conducts sound. Eddy current necessitates the material to be an electrical conductor.
- By understanding these distinctions, one can make informed decisions when choosing between UT and ET for specific non-destructive testing needs.
