FluxCored Arc Welding Welding involves joining different materials together. In the welding process a good amount of 'melting' of the metals takes place while fixing two metals together, andn this is what differentiates it from soldering and brazing. Usually metals or thermoplastics are used in the welding process. Fluxcored arc welding (FCAW) is one of the popular welding processes. It is an automatic or semiautomatic arc procedure. Introduced in the 1950s, this process involves the use of a new kind of wire electrode on an MIG welding machine. This is the reason why fluxcored is regarded as similar to MIG welding process. The equipments used in both the processes are same, so are wire fields and power supply. The wire used in this purpose is the tubular wire and not that the usual solid wire. Basically there are two types of fluxcored wire: a. Selfshielded b. Dual Shield While selfshielded wires do not use any external gas shield, rather they employ the flux to shield the molten weld puddle; dual shield wire uses both the external shielding gas as well as the flux to protect the molten weld puddle. Usually carbon dioxide and argon are used as shielding gases in dual shield flux cored wire. If we compare fluxcored arc with MIG welding process, then it is has greater productivity. While a MIG welder can produces on an average 5 to 8 pounds of weld in an hour, FCAW produces above 25 pounds of weld per hour. Along with higher productivity, fluxcore welding
