Flux-Cored Welding: The Basics for Mild Steel

01.06.2010· Self-shielded flux-cored welding is a wire welding process in which a continuous hollow wire electrode is fed through the welding gun into the weld joint. Self-shielded flux-cored welding differs from MIG welding in that it doesn’t require an external shielding gas, such as carbon dioxide or argon, to protect the weld pool from contamination.

Flux Cored Wire - an overview | …

The equipment is similar to MIG/MAG but uses a flux-cored wire (Fig. 5.7). An arc is formed between a continuously fed tubular electrode wire containing a flux and the work. The arc is protected by a gaseous shroud formed by the flux melting. An external secondary shielding gas can also be supplied through the torch (Fig. 5.8).

Flux-cored arc welding - Wikipedia

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.An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon to generate …
