Abstract

Nondestructive test systems are increasingly applied in the industrial context for their strong potentialities in improving and standardizing quality control. Especially in the service stage of rail, early detection of nucleus defects in the rail can avoid the broken rail accident. The aim of present work is to propose a kind of non-contact nondestructive testing method based on the laser and electro-magnetic acoustic transducer techniques, which is suitable to inspect the nucleus defects. This paper describes the testing system, principle and signal processing. The result shows the relative error of testing nucleus defects is about 3.24 %.
