Abstract

In this article, the introduction of a new NDT system that utilises two different non-contact techniques in a complementary mode, namely Electromagnetic Acoustic Transducers (EMATs) generating surface ultrasonic waves, and Pulsed Eddy Current (PEC) sensors, is reported. Being non-contact, both lend themselves to automatic on-line inspection that can benefit inspection of materials during the manufacturing process and whilst in service. This paper also highlights other potential benefits and presents some preliminary experimental results
