Eddy current testing (ECT) is a nondestructive testing (NDT) technique used to detect surface and sub-surface defects using principles of electromagnetic induction. ECT offers tremendous flexibility in its ability to not only detect surface cracks, but also sub-surface indications. In the 1980s, ECT was considered the next big NDT technology and was touted as a replacement for magnetic particle inspection (MPI), but it never really took off as expected and the demand for ECT remained relatively stable. In the past two years though, ECT has witnessed large-scale adoption and demand across industries with many experts suggesting that the technique may finally reach its potential market. This article will provide a brief timeline of some of the major developments in ECT as an NDT technique, aim to decipher the reasons for its slow adoption and provide a picture of the future potential for ECT.
