Flux Cored Arc Welding
Return to welding history
Flux-cored arc welding (FCAW) is a common 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. The use of an externally supplied shielding gas is optional creating the primary process variation:
-
FCAW–S (self-shielded or “open-arc”)
-
FCAW–G (gas-shielded)
FCAW key process variables
-
Wire feed speed (and current)
-
Arc voltage
-
Electrode extension
-
Travel speed
-
Electrode angles
-
Electrode wire type
-
Shielding gas composition (if required)
FCAW applications
-
FCAW may be an “all-position” process with the right filler metals
-
A high-deposition rate process in the 1G/1F/2F
-
Some “high-speed” (e.g., automotive applications)
Used on the following alloys:
-
Mild and low alloy steels
-
Stainless steels
-
Some high nickel alloys
-
Some wearfacing/surfacing alloys
