Abstract:Acoustic Emission (AE) technique has been successfully used to monitor processes like metal cutting, grinding and electron beam welding as a nondestructive evaluation method. Friction Stir Welding (FSW) is a solid state welding that avoids problems associated with fusion welding and is used in aerospace industries. An attempt has been made to study the application of AE technique to monitor FSW process by identifying the occurrence of defect while welding is in progress and suggest means to rectify the defect.… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
