摘要：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. FSW is considered to
be the most significant development in metal joining in a decade. Recently, friction stir processing (FSP) was
developed for microstructural modification of metallic materials. Because melting does not occur and joining takes
place below the melting temperature of the material, a high-quality weld is created. This characteristic greatly reduces
the ill effects of high heat input, including distortion, and eliminates solidification defects. Friction stir welding also is
highly efficient, produces no fumes, and uses no filler material, which make this process environmentally friendly..In
this project we have designed circular tool by using creo-2 and then applied static (tool rotational velocity 1000 rpm)
and thermal (temperatures’ and convection on plates and tool also) boundaries conditions And calculated results like
deformation stress and heat flux etc. Here we also designed 3 more tools hexagonal and tapered and truncated and
applied same boundary condition with same material properties and calculated all results from all these results which
tool can be used in the place of circular tool.
