Final answer:
In Flux-Cored Arc Welding (FCAW), the filler metal is provided by the material in the flux-cored wiring, improving efficiency and convenience in the welding process.
Explanation:
The filler metal in an FCAW process is provided by the material in the flux-cored wiring. In Flux-Cored Arc Welding (FCAW), the filler metal is contained within the tubular wire electrode. When the wire is melted, it creates the weld bead by providing the necessary filler metal to join the pieces being welded. This method eliminates the need for separate filler metal rods, making the process more efficient.
