Is eddy current testing expensive?

Eddy current testing equipment prices vary, based on the capabilities of the equipment and the accessories needed for specific applications, in the same way that commuter sedan prices differ from those of city busses. However, eddy current testing equipment prices pale in comparison to the costs of missed inspections.

What is eddy current testing equipment?

Eddy current instruments are NDT instruments that induce detectable eddy currents in conductive materials. They are used to detect flaws, determine thickness, inspect welds, measure conductivity, and sort alloys.

How accurate is eddy current testing?

In favorable conditions, Eddy Current Testing can test fault in pipes up to 0.5 millimeters. With the proper equipment, the right type of conductive material, and properly trained professional, this test is extremely accurate at pinpointing even the smallest of faults. It can detect through coated materials.

How often should eddy current testing be done?

approximately every 3 to 5 years
Ideally, testing will occur approximately every 3 to 5 years, possibly more frequently if there is active damage occurring that should be monitored. Including eddy current testing in an annual inspection ensures that testing occurs with the proper regularity.

Is eddy current volumetric?

Several benefits are derived from eddy current testing: It is suited to volumetric flaws such as corrosion, wear, and large porosities, as well as cracking. It can detect surface-breaking, near-surface, and far-surface defects.

How does eddy current testing work?

How Eddy Current Testing Works. Relying on the process of electromagnetic induction, an alternating current flows through a wire coil and produces a fluctuating magnetic field in an eddy current probe. The testing procedure uses an ECT probe, which is a coil of conductive wire that is excited by the alternating electric current.

What is eddy current testing (ECT)?

Eddy-current testing (also commonly seen as eddy current testing and ECT) is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials.

What is an eddy current inspection?

Eddy current inspection is a surface inspection method for conductive materials. It utilizes electromagnetic induction to find linear indications and to differentiate between different materials. This test method is excellent for research and development applications.

What is the abbreviation for eddy current inspection system?

Eddy-current testing (ECT) is employed in most inspection works since wheels can be tested without removal of paint and varnish whereas the liquid penetrant method is applied only if the surface is free of coating.
