A study of process parameters of friction stir welded AA.
Friction stir welding is a solid state welding technology used for welding low melting point metals such as al, mg its alloys. friction stir welding ( fsw) is fairly a recent technique that uses a non consumable rotating welding tool to generate frictional heat and plastic deformation at the welding location while the material is in solid state.

Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding.

Tools for Friction Stir Welding R. R. Rai, A. De, H. K. D. H. Bhadeshia and T. DebRoy Abstract. Friction stir welding (FSW) is a widely used solid state joining process for soft materials such as aluminium alloys because it avoids many of the common problems of fusion welding.
The research efforts are principally focused on the effect of the forming parameters of very diverse processes (forming, solid phase (friction) or liquid (TIG, SMAW, etc.) brazing and additive manufacturing, materials implantation and deposition) on the microstructural aspect of the junction ensuring the cohesion and required properties of the.
Since its development in ’90, Friction Stir Welding (FSW) had known an important growth, especially for the hard to weld aluminium alloys. For these FSW has been shown to produce welds of high quality with no defects, reduced cost and lower environmental impact when compared to traditional fusion welding. The process parameters influence on the connection formation is related.
