History of the flux cored wire:

Flux-cored wires have been around since the 1950s and are available in two main versions: gas-shielded and self-shielded. Both types are composed of an outer sheath and are filled with flux, a compound that is a mixture of alloys and deoxidizers, the latter of which are necessary to protect the weld from contaminants.

As their name implies, gas-shielded flux-cored wires require an external shielding gas supply to protect the weld; self-shielded wires do not. The flux in self-shielded wires generates the shielding gas, which makes these wires highly portable and ideal for outdoor welding applications, such as structural steel, shipbuilding, and bridge construction. Common applications for gas-shielded flux-cored wires include general fabrication ,pressure vessels, petrochemical piping, and heavy-equipment manufacturing.
