Flux-Cored Arc Welding (FCAW) is a semi-automatic or automatic welding process that uses a continuously fed tubular wire filled with flux. The flux generates a shielding gas when heated, protecting the weld pool from contamination. This method is effective for welding thick materials and is commonly used in construction and manufacturing. FCAW can be performed in various positions and is suitable for both indoor and outdoor applications. It offers high welding speeds and can be used with or without an external shielding gas, making it versatile for different environments and materials.
