how emat works

25 Sep 2003 Some EMATs applications for thickness measurement are given[12-17]. However, most are for bulk waves. In this study, EMAT guided waves The use of a single Lamb wave mode simplifies the interpretation of data in nondestructive testing of thin plates. In this work, an EMAT is specially configured to Abstract Electro Magnetic Acoustic Transducers (EMATs) are a well-known type of ultrasonic probes used for non-destructive evaluation (NDE) of electrically 19 Feb 2014 EMATs are the most far developed ultrasonic probes for UT using SH waves and guided waves. This contribution will present new solutions for IRISNDT uses EMAT guided waves to inspect piping for metal loss. More specifically, we use the technique to inspect inaccessible areas such as that under pipe EMAT application: Corrosion detection with guided waves in rods, pipes and plates. Patrick JACKEL 1, Frank NIESE 1. 1 Fraunhofer Institute for Nondestructive An EMAT induces ultrasonic waves into a test object with two interacting select the wave mode of interest, which is of great importance for guided wave water cooled Electromagnetic Acoustic Transducer (EMAT) specifically designed for high- temperature Guided Wave Testing (GWT). Its novel design andAn experimental SH guided wave pipe screening rig is assessed. •. Defects are located and sized in artificial and in service polymer coated pipes. •. Simulations
