Welding wire is used as metal filling stuff or at the same time as metal wire welding materials for electric conduction. In gas welding and tungsten pole gas shielded arc welding, the welding wire is used as filling metal; in submerged arc welding, electroslag welding, and other melting pole gas shielded arc welding, the wire works both  as filling  metal also conductive electrodes. Welding wire can be divided into three categories. The wire surface does not require flux for anti- oxidation.

1.Rolled Welding Wire. Most welding wire falls into this category, including carbon steel wire, low-alloy steel wire, alloy structural steel wire, stainless steel wire and nonferrous metal wire, etc.
2.Casting Welded Wire. Some alloys, such as cobalt-chromium-tungsten alloy can not be made by forging, rolling, and drawing, can only be made by casting. Casting welding wire is mainly used for manual welding workpiece surface in order to meet special property requirements such as anti-oxidation, anti-wear and high temperature corrosion resistance, and other special performance requirements. Use of continuous casting and liquid extrusion can produce up to a few meters of cobalt chromium tungsten wire, tungsten wire for automatic filling gas shielded arc welding, in order to enhance welding efficiency and quality of cladding layer, while also improving the working conditions.

3.Flux-cored welding wire. A thin strip rolled into round or shaped steel tubing, with the filling of powder of certain extent, then into seam flux cored welding wire through drawing, or seamless flux-cored welding wire with tubes filling completely with powders. Welding with this wire has good welding deposition efficiency, good adaptability of steel and wide range of uses. This wire is mainly used for carbon dioxide gas shielded welding, submerged arc and electroslag welding. The powder flux cored wire electrode composition contains slag, building gas and solid components of the flux-cored wire arc welding without shielding gas. The self-shielded flux-cored wire is suitable for large welded structure and the construction works.
