Flux-Cored 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, and this is what differentiates it from soldering and brazing. Usually metals or thermoplastics are used in the welding process. Flux-cored arc welding (FCAW) is one of the popular welding processes. It is an automatic or semi-automatic 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 flux-cored is regarded as similar to MIG welding process. The equipment's 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 flux-cored wire: Self-shielded Dual Shield While self-shielded wires do not use any external gas shield, rather they employ the flux to shield the molten weld puddle;...
