What is Flux-Cored Arc?

Flux-Cored Arc Welding (FCAW) is an arc welding process that uses a continuously fed consumable flux-cored electrode and does not require an externally supplied shielding gas (though it can be used). The flux within the electrode provides the shielding gas and deoxidizers necessary to produce a sound weld. It is commonly used in heavy fabrication, construction, and repair work, especially for welding thicker materials and in outdoor environments where wind could disrupt gas-shielded processes. FCAW offers high deposition rates and good penetration.
