Flux cored wire is a rapid development in recent years a new type of welding materials, and have access to a wide range of applications in industrialized countries. According to information on: Japan from 1985 to the present its electrode accounted for the proportion of the entire welding consumables decreased from 45% to 20%;  Welding Wirethe proportion has reached nearly 30%. In the U.S. electrode proportion dropped to less than 40%, flux cored wire is close to 40%; Western European countries electrode about 30%, about 20% of flux cored wire. Thus, over the past decade the proportion of traditional electrode of the industrial countries is declining, while the ratio of the flux cored wire throughout the welding consumables has substantially increased. Flux cored wire and hand-welding rods and welding wire has a distinct advantage compared to intermittent welding process into a continuous mode of production, thereby reducing the number of welded joints and improve weld quality, but also increased production efficiency, saving energy. Flux Core Welding Wireis also known as tubular wire can easily design a variety of different uses of welding material types and proportions of additives by adjusting the drug core, flexibility and easy adjustment of the alloy composition, flux cored wire The variety is solid wire can not be smelting and rolling. Flux cored wire again into the seam and seamless flux cored wire, seamless flux cored wire finished silk processing copper wire custody in the process of moisture resistance and electrical conductivity in the welding process, are superior to slit cored wire.
