When welding, it is used as a filler metal or as a conductive wire for conductive materials. In the gas welding and tungsten gas protection arc welding, the wire used as a filler metal; in submerged arc welding, electroslag welding and other melting gas protection arc welding, the welding wire is both filled with metal, but also conductive electrodes. Welding wire can be divided into three categories. The surface of the wire is not coated with an oxidative flux.Welding Wire
Casting wire: some alloys, such as cobalt chrome tungsten alloy, not forging, rolling and wire drawing, and made by casting method. It is mainly used for manual surfacing of the workpiece surface to meet specific requirements such as oxidation resistance, abrasion resistance and corrosion resistance at high temperatures. The use of continuous casting and liquid extrusion can produce up to several meters of cobalt chromium tungsten wire for automatic wire tungsten gas arc welding to improve welding efficiency and surfacing quality, but also to improve working conditions. Cast iron welding is sometimes used casting wire.Welding Wire
Flux-cored wire: round with a thin strip or shaped steel pipe, filled with a certain component of the powder, made by the seam of the flux cored wire, or filled with steel pipe drawn from the seamless flux cored wire. With this welding wire welding high efficiency, good adaptability to steel, the trial cycle is short, so its use and use of the ever-expanding. This wire is mainly used for carbon dioxide gas shielded welding, submerged arc welding and electroslag welding.Welding Wire
Flux-cored wire in the powder composition is generally similar with the electrode coating. Contains slagging, gas and stable components of the flux-cored welding wire does not need to protect the gas, said self-protection flux cored wire, suitable for large-scale welding structural engineering construction.Welding Wire
