English
Welding material used as a filler metal or as a conductive wire. Welding wires are used as filler metals in welding and tungsten gas shielded arc welding, and when submerged arc welding, electroslag welding and other gas shielded arc welding, the welding wire is both a filler metal and a conductive electrode. Welding wire can be divided into 3 categories.Welding Wire
① rolling Wire: Most of the wire belongs to this category, including carbon steel wire, low alloy structural steel wire, alloy structural steel wire, stainless steel wire and non-ferrous metal wire.
② cast Wire: Some alloys, such as cobalt-chromium-tungsten alloys, cannot be forged, rolled, and shaped, but made with casting methods. It is mainly used for manual surfacing of workpiece surface to meet special performance requirements such as anti-oxidation, abrasion resistance and corrosion resisting at high temperature. The use of continuous pouring and liquid extrusion can produce a number of meters of cobalt-chromium-tungsten welding wire for automatic tungsten electrode gas shielded arc welding, in order to improve welding efficiency and the quality of surfacing layer, but also improve working conditions. Cast iron welding wire is sometimes used to repair.Welding Wire
③ flux-cored wire: With thin steel tape rolled into a circular or profiled steel tube, filled with a certain component of the powder, the tension made of slotted flux-cored wire, or filled with a steel tube to pull the powder made of seamless flux-cored wire. With this welding wire weld The high efficiency, good adaptability to the steel, trial-production cycle is short, thus its use and use of the scope of expanding. This kind of welding wire is mainly used for carbon dioxide gas shielded welding, submerged arc welding and electroslag welding. The powder composition in flux cored wire is generally similar to that of the electrode. The flux cored wire, which contains slag, gas-making and ARC-stabilized components, does not need to be protected when welding, and the self shielded flux-cored wire is suitable for the construction of large-scale welded structural engineering.Welding Wire
