Abstract

This is a brief report on some early work on the testing of steel sheets using pulsed eddy currents. Penetration up to about 10 mm has been achieved and some artificial defects have been observed. Longer pulses are to be employed for deeper penetration, and more work done on the observation of defects. Some theoretical work is also reported. An indication is given of further work and the preparation of computer programs to produce a calculated output pulse where the input pulse shape is known.
