Abstract:Capacitor discharge welding (CDW) is analysed to repair aeronautical components made with Inconel 718 and Ti 6 Al 4 V alloys, currently used for compressor and turbine applications.The CDW process is a resistance welding technology; it makes use of high-intensity current pulses, discharged by large capacitors. The use of multipoint contact features allows us to reduce stress concentration effects at the weld toe, obtaining thin weld beads, and achieve good material continuity.Base material and as-welded specim… 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.
