Eddy Current Testing

The eddy current inspection service, provided by Caparo Testing Technologies, is an electromagnetic non destructive testing technique used extensively by our clients in the aerospace, automotive, power generation, marine, manufacturing and many other industries. As a fast and reliable method of identifying a range of potential problems, such as cracks, small component flows, size and material variation, it provides the ability to update materials, components and entire mechanisms rapidly and in a cost effective manner.

As a company, we have extensive experience in the aerospace industry, working with a number of commercial airline businesses in both Europe and the Middle East. Using our eddy current inspection service, for example, we perform thousands of aircraft crack detection inspections every year. Constructed from multi layered skins, and held together by fasteners, aircraft are often subjected to continuous stresses, which can cause for fatigue cracks to be introduced into the vicinity of their fastener holes. Eddy current testing is not only a highly efficient but also the most expedient method of detecting flaws, saving our customers time and money and protecting them from potential disaster. In addition, this type of non destructive testing can also be used to measure material thickness in the process of detection and characterisation of corrosion damage on the skin of the aircraft.

In power generation, Caparo Testing Technologies often applies eddy current inspections to tubing in heat exchangers and steam generators. Detecting corrosion, erosion, cracking and other changes in tubing is especially important for nuclear power plants where reused, contaminated water must be prevented from mixing with fresh water that will be returned to the environment. The eddy current test method provides high-speed, consistent inspection technique for these applications.

Other applications of this non destructive testing service include:
• Measurement of metal thickness;
• Determination of coating thickness – widely applied to measure the thickness of plastic and paint coatings in a variety of industries;
• Measurement of electrical conductivity and magnetic permeability – used in many industries for sorting metals, checking for proper heat treatment, and inspecting for heat damage.
