What is ECT?

Eddy Current Testing (ECT) is a form of non-destructive testing (NDT) performed on non-ferromagnetic metals through electromagnetic induction. (Return to Top)

What are eddy currents?

Eddy currents are loops of electric current inducted in conductors through changing magnetic fields. Their name stems from the swirling votricies seen in fluid dynamics, which are called eddies. (Return to Top)

Where are you located?

Eddy Current USA, Inc. is based out of northern Minnesota, and we gladly service work all throughout the Great Lakes and Midwest region. (Return to Top)

What is ECT useful for?

ECT has many, widely varying applications related to the non-destructive testing of non-ferromagnetic metals. Eddy Current USA, Inc. specializes in the testing of tubular products (i.e. bobbin coil testing), particularly those products found within chillers and heat exchangers. (Return to Top)

What can ECT detect?

ECT is useful for detecting large volume, small volume, and circumfrencial cracking, pitting, and corrosion. (Return to Top)

How often should our equipment be tested?

Due to its non-destructive nature, there is no minimum amount of time or times an ECT procedure can be performed. Depending on the vessel being tested however, Eddy Current USA, Inc. typically recommends a test to be performed every 2-5 years. (Return to Top)

Where can I learn more about NDT?

While there are many places to learn about the history and application of non-destructive testing (NDT), we consider the American Society for Non-Destructive Testing (ASNT) to be the authority. (Return to Top)
