The electrodes used in flux-cored arc welding are made up of a flux core, surrounded by a metal sheath. The primary function of flux at the core of the wire is to provide shielding to the arc from the oxidizing gases in the atmosphere such as oxygen and nitrogen. The metal sheath accounts for 75 to 90% of the weight of the wire.<\/p>\n\n\n\n
For some FCAW electrodes, a supplemental shielding is also provided in the form of a shielding gas. The composition of the wire, flux in the core, and the shielding gas determine the ultimate chemical and mechanical properties of the deposited weld metal with that wire.<\/p>\n\n\n\n
A typical wire used in FCAW process is illustrated in the figure 1 below. For carbon steel electrodes, the flux at the core simply performs the function of providing shielding to the arc.<\/p>\n\n\n\n
