This compendium is a compilation of technical articles on the guided wave test method published in ASNT's Materials Evaluation and The NDT Technician newsletter from 1996 through 2014. It was compiled at the request of the Guided Wave Testing Committee of the ASNT Technical and Education Council in order to provide reference material for the development of the GW body of knowledge included in ANSI/ASNT CP-105 (2016). This compendium is also one of the references used in the development of the ASNT NDT Level III examination for GW. The research and findings contained in this compilation offer real-world and laboratory-tested insight into the field of GW and can be useful to a diverse readership. For students, this is an invaluable tool toward a greater understanding and overall knowledge of GW. For the seasoned technician, the compendium serves as a reference that documents past and present articles on the method. ISBN: 978-1-57117-371-3
