Fluxed-cored
Arc Welding (FCAW)
The Fluxed Cored Arc Welding (FCAW) process
is also referred to as “fluxed cored”.
In FCAW, a continuous solid wire is fed
through the welding gun from a wire feeder.
The wire consists of a metal sheath filled
with a flux. The flux helps to establish
the arc, provides additives to the weld,
and produces a slag.
In gas-shielded FCAW, the shield gas (mix
of carbon dioxide & inert gas) is used
to protect the arc. In self-shielded FCAW,
the flux decomposes to produce the shielding
gas and slag. FCAW is used to weld mild
and alloy steel and generates large amounts
of fumes.
