A Review on Friction Stir Welding of Steel

Friction stir welding is a solid state welding technology used for welding low melting point metals, such as Al, Mg and its alloys. Later welding was conducted on dissimilar metals which also produced a better defect free joint. Tool design and welding parameters contributes a major role for producing a better weld. Material flow and friction heat are the factors that the internal factor
