Eddy Current Testing Applications. For this materials such as nickel alloy, ferrite chromium etc. testing can be done by permeability variation suppressed by applying magnetic field. Saturation probes contains conventional eddy current coils and magnets. Remote field eddy current testing is the procedure for carbon steel tubing testing. Some facts on testing of eddy currents. Applications. Eddy current testing can be used for a wide range of applications. It is often applied for surface crack detection and material sorting. Material sorting is used to ensure that the proper materials are in use and to verify component materials or assembly features (such as the orientation or position of a subcomponent in an assembly). Basic Principles of Eddy Current Inspection. Eddy current inspection is one of several NDT methods that use the principal of electromagnetism as the basis for conducting examinations. Several other methods such as Remote Field Testing (RFT), Flux Leakage and Barkhausen Noise also use this principle.
Metal Detectors: It detects present of metals inside rocks, soils etc. with the help of eddy current induction in the metal if present. Data Processing Applications: Eddy current non destructive testing used in investigating composition and hardness of metal structures. Speedometer and Proximity Sensing Applications The two major applications of eddy current testing are surface inspection and tubing inspections. Surface inspection is used extensively in the aerospace industry, but also in the petrochemical industry. The technique is very sensitive and can detect tight cracks. Surface inspection can be performed both on ferromagnetic and non-ferromagnetic.
An Eddy current can be produced by both electromagnets and permanent magnets, as well as transformers and by the relative motion generated when a magnet is located next to a conducting material. Eddy currents are used in specific applications, including non-destructive testing, which are discussed in this article.
High quality eddy current testing solutions for complete inspections. Zetec is the industry leader for cost-effective eddy current testing (ECT) in complex applications. We have the most extensive experience, and we develop the highest quality ECT inspection products. Eddy-current flaw detectors. eddy current flaw detector Eddycon is referred to the testing and evaluation means.It is intended for manual testing by eddy current technique for the presence of surface and subsurface defects, such as discontinuity of the material (cracks, overlaps, holes, fine cracks, etc.) Read more... Eddy current testing is one of several non-destructive testing methods that uses the electromagnetism principle for flaw detection in conductive materials. A specially designed coil energised with an alternating-current is placed in proximity to the test surface, generating a changing magnetic field that interacts with the test-part and. Applications. Eddy current testing can be used for a wide range of applications. It is often applied for surface crack detection and material sorting. Material sorting is used to ensure that the proper materials are in use and to verify component materials or assembly features (such as the orientation or position of a subcomponent in an assembly).
