Flux-cored arc welding (FCAW) 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 supplied, but often the flux itself is relied upon to generate the necessary protection from the atmosphere. The process is widely used in construction because of its high welding speed and portability.


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) Note: FCAW wires that don't require a shielding gas commonly emit fumes that are extremely toxic; these require adequate ventilation or the use of a sealed mask that will provide the welder with continuous fresh air.



FCAW APPLICATIONS

  • FCAW may be an "all-position" process with the right filler metals

  • No shielding gas needed

  • 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
