Abstract

The aim of this research is to make a high performance EMAT, highly sensitive, with low electric power consumption and wireless data communication. For this purpose, we introduced the following new devices and techniques into the EMAT: 1) A high efficiency power supply circuit to generate a strong oscillating magnetic field in the excitation coil, and 2) Effective use of high quality noise reduction to increase S/N ratio of the received signal. This EMAT system detects fatigue cracks in thick austenitic stainless steel 316L specimens by angle beam inspection as well as detecting EDM slits by the normal beam method.
