Eddy Current Testing Market Sees Phenomenal Growth, Predicted to Reach US$ 2.6 Billion by 2032

The global eddy current testing market is forecasted to reach a value of US$ 2.6 billion by the year 2032. This market is anticipated to experience consistent growth, with a CAGR of 8.3% from 2022 to 2032. To put things in perspective, in 2022, the global market for eddy current testing was valued at US$ 1.1 billion.

When doing eddy current testing, a specifically created coil that is controlled by a current that flows is brought close to the testing area. It helps to create a fluctuating magnetic field that interacts with a particular sample. Eddy current measurements are also produced as a result.

Eddy current testing is the basis for the physics phenomenon known as electromagnetism. An alternating current passing through a wire coil creates an oscillating magnetic field in an eddy current sensor.

When a magnet and its magnetosphere are brought close to an electrical conductor, eddy currents, or the moving round electrons, begin to flow through the metal. It resembles a test piece made of metal.

The eddy current in the metal would combine with the magnetic field of a coil. Via mutual inductance, it would generate its own magnetic field.

A knowledgeable user can map fluctuations in resistivity loudly using eddy current equipment. In seeking out changes in the substance that is to be measured, phase differences can also be used. The global market is expected to rise as new eddy current testing methods are invented.

Average penetration is defined as the point where the eddy flow rate is 37% of the surface value. The test frequency, polarizability, and conductivity of test samples can all be used to calculate this depth.

Changes in the conductivity of test materials might have an impact on precision, test receptivity, and solubility. It can also be influenced by the coil’s design, velocity of the AC impulses driving the circuit, and the material’s magnetic permeability.

High standards for substance, design, and durability are required by the global aircraft industry. Numerous fatal occurrences and grave injuries can result from smoothness, roughness, and crevice breakdowns.

Competitive Landscape: Eddy Current Testing Market

To develop novel solutions, leading businesses in the worldwide eddy current testing market are concentrating on research and development operations. Other businesses are forming alliances, mergers, and acquisitions with regional small businesses. They are doing so to increase their geographic presence and jointly develop novel solutions.

For instance,

In June 2021, ETher NDE announced the launch of ETi-300n. It was developed to improve the end-to-end workflow of inspection. It is an eddy current equipment that was developed to inspect the non-ferrous tubing from an inner diameter and deliver accurate inspection results.

Market Growth Drivers: One of the primary drivers propelling the growth of the eddy current testing market is the rising emphasis on safety and quality assurance across industries such as aerospace, automotive, manufacturing, and electronics. With stringent regulations and standards governing product quality and safety, manufacturers are increasingly adopting advanced inspection technologies like eddy current testing to ensure compliance and mitigate risks.

Moreover, the growing adoption of automated inspection systems is fueling market expansion. Automation not only enhances the speed and accuracy of inspections but also reduces operational costs and minimizes human error. This trend is particularly prominent in industries with high-volume production, where the efficiency gains offered by automated eddy current testing systems are invaluable.

Technological Advancements: Advancements in eddy current testing technologies have played a pivotal role in widening the application scope and improving the efficacy of this inspection method. Innovations such as phased array eddy current testing (PAECT) and remote field testing (RFT) have enabled more precise defect detection, especially in complex geometries and hard-to-reach areas. Furthermore, the integration of artificial intelligence and machine learning algorithms into eddy current testing systems is enhancing defect recognition capabilities and reducing false positives, thereby boosting the reliability of inspection results.
