Flux-cored arc welding, or FCAW, is a common welding technique that has existed since the 1950s. Arc welding uses an electric arc to generate heat that melts and ultimately binds metal. Since flux-cored welding is taught in welding training programs, here is a brief overview of this welding method. What is fluxed cored welding? Flux-cored arc welding is a semi-automatic or automatic arc welding process. This arc welding technique creates an electronic arc through a continuously fed consumable tubular electrode containing a flux (flow) and a constant voltage welding power supply.
