Flux-Cored Wire

Flux-Cored Wire vs Solid-Cored Wire

Professional welders are well aware that the flux-cored wire is improved to offer performance that is simply not possible with a solid wire. That is why, the commercial welders prefer to use Flux-Cored wire over Solid-Cored gas wire in many welding applications including flat welding and vertical-up welding, welding over galvanized or welding hard-to-weld steels. The Solid-Cored wire is more popular and is easier to weld, as it needs cleaner steel and thus it is hard to maintain the fusion for out of position welding.

Gas-Shielded vs Self-Shielded Flux

Commercial welders use two types of Flux Wires: Gas Shielded and Self-Shielded. The gas shielded flux cored wire works with external shielding gas from a bottle and has a flux coating that solidifies rather quickly compared to the molten welded materials. The commercial welders use Gas Shielded Flux-Cored wire when they are welding thicker metals or in different out of position welding applications. The Self-Shielded Flux wire does not request for external shielded gas as the weld pool is protected by the gas which is generated form the flux when the wire is fed and burned. The Self-Shielding Flux Wire is more versatile and ready for on-the-go welding applications as there is no need of external bottles.
