Flux Cored Arc Welding (FCAW)

Flux cored arc welding (FCAW) uses a flux core electrode wire that is continuously fed from a spool, through the welding cable assembly, and out through the welding gun.

Equipment and Uses

Flux cored arc welding works well with welding most carbon steels, cast iron, stainless steel and hard facing / surfacing alloys. It is a flexible welding process suitable for all position welding, given the correct filler material and flux composition.

The basic arc welding equipment consists of a power source, controls, wire feeder, welding gun, and welding cables.

 

Types of Wires used:

Self-shielded flux-cored wires (FCAW-S) produce their own shielding gas when the arc initiates, eliminating the need for an external gas cylinder and making them suitable for use in portable and remote applications. 

Gas-shielded flux-cored wires (FCAW-G) require an external shielding gas of either 100 percent CO2 or a blend of argon and CO2. They tend to have a higher operator appeal, meaning they are easier to control and to use to produce an aesthetically pleasing weld.
