Flux-cored ARC welding (FCAW or FCA) is a semi-automatic or
automatic arc welding process. FCAW requires a continuously-fed
consumable tubular electrode containing a flux and a
constant-voltage or, less commonly, a constant-current welding
power supply. An externally supplied shielding gas is sometimes
used, but often the flux itself is relied upon to generate the
necessary protection from the atmosphere, producing both gaseous
protection and liquid slag protecting the weld. The process is
widely used in construction because of its high welding speed
FCAW was first
developed in the early 1950s as an alternative to shielded metal
arc welding (SMAW). The advantage of FCAW over SMAW is that the
use of the stick electrodes used in SMAW is unnecessary. This
helped FCAW to overcome many of the restrictions associated with

E71T-1C is a most popular flux cored wire designed for single or
multi pass welding having a smooth arc transfer, low spatter,
flat to slightly convex bead contour, with a high deposition
rate and easily removal slag. This all-position wire has
excellent feeding and low fume generation using 100% CO2 making
it a good choice for mild steel and higher strengths steels.
Argon - CO2 gases may be used if tested with application.
There are two types of
flux-cored wire electrodes: gas-shielded and self-shielded. As its name
implies, the gas-shielded type of flux-cored wire requires an external shielding
gas. The self-shielded variety does not.
The flux coating on gas shielded
flux-cored wires solidifies faster than the molten weld material. Consequently,
a sort of shelf is created which holds the molten pool when welding overhead or
vertically up. Gas-shielded flux wires work well when welding thicker metals.
They also work well for welding out-of-position applications. Slag removal is
easy with this type of wire.
Self-shielding flux-cored wires
do not require an external shielding gas. With this type of electrode, the weld
pool is protected as gas is generated when the flux from the wire is burned.
Because the self-shielding wire produces its own protective shield and doesn't
require an external gas tank, it is more easily carried about.
Advantages of Flux-Cored Wire
There are several advantages of using flux-cored wire electrodes. These advantages include but are not limited to:
- They allow for a high
- They work well outdoors and
in windy conditions.
- With the right filler
materials, these electrodes can make FCAW an all-position process.
- Typically, flux-cored wires
create clean, strong welds.
Disadvantages of Flux-Cored Wire
There are concerns with any type
of welding method. Regardless of the process and type of electrode used, there
is the possibility of creating an incomplete fusion between the base metals.
Slag inclusion or cracks in the welds may also result.
Additional problems that may
arise when using flux-cored electrode wires include:
- A melted contact tip may
occur if the electrode contacts the base metal and fuses the two together.
- If gases do not escape the
welded area before the metal hardens, the weld may develop holes and become
Which Wire is the Best Choice?
When comparing the flux-cored
wires to the solid wires, it would be wise to note that the best choice is
dependent upon the welding job and location. Both types of wires can produce
sound welds with good weld bead appearances, when done correctly.
For thicker metals and outdoor
jobs, the flux-cored wire electrodes work best. For thinner metals and jobs
performed out of the wind, solid wire electrodes can work quite well. Solid wire electrodes used in
MIG welding are not as portable as flux-cored wires. This is due to the
necessity of a shielding gas in MIGW. Both solid wire electrodes and
flux-cored wire electrodes are relatively easy to use. However, flux-cored wire
electrodes are more costly.
