Over the years, eddy current testing (ECT) has evolved significantly, driven by advances in technology and changing industry needs. Historically, ECT has been primarily a manual and technician driven process, dependent on the human eye and technician experience to discern differences in the signals produced during the critical inspection. However, with the advent of improved instrumentation and transition to eddy current array probes (ECA), this inspection process is becoming more objective and precise, with greater accuracy and consistency across various industries.
