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 .

The nature of the CV machine is required by gas metal arc welding and flux-cored arc welding because the welder is not able to control the arc length manually. [ citation needed ] If a welder were to attempt to use a CV machine for a shielded metal arc welding (SMAW) task, the small fluctuations in the arc distance would cause significant ...
Gas metal arc welding Man welding a metal structure in a newly constructed house in Bengaluru, India. Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a joining of the metals.
Rosin used as flux for soldering A flux pen used for electronics rework Multicore solder containing flux Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time.
The flux powder is supplied by the hopper on the left hand side, then follow three filler wire guns and finally a vacuum cleaner.

In recent years its use has declined as flux-cored arc welding has expanded in the construction industry and gas metal arc welding has become more popular in industrial environments. However, because of the low equipment cost and wide applicability, the process will likely remain popular, especially among amateurs and small businesses where ...
C-50 (50% argon/50% CO 2) is used for short arc welding of pipes, C-40 (60% argon/40% CO 2) is used for some flux-cored arc welding cases. Better weld penetration than C-25. C-25 (75% argon/25% CO 2) is commonly used by hobbyists and in small-scale production. Limited to short circuit and globular transfer welding.
