friction stir tooling tool materials and designs
Commonly used tool materials Tool steel Materials such as aluminium or magnesium alloys and aluminium matrix composites AMCs are commonly welded using steel tools817 Steel tools have also been used for the joining of dissimilar materials in both lap and butt configurations1825 Lee et al18 welded AlMg alloy with low carbon steel in lap joint. Friction stir welding FSW was invented by TWI in 1991 1 and substantial development has been conducted subsequently.

Making a choice in selection of friction stir weldingprocessing FSWP tool material has become an important task which determines the quality of the weld produced.
. Materials welded experience plastic deformation at elevated temperatures creating a weld zone consisting of a wrought microstructure instead of the solidification microstructure produced by fusion welding methods 1 2 3. Tool Design The tool must be designed to generate. Along the way several successful new tooling designs were developed for current issues at the.
Production engineering Delhi Technological University India. Is a screw threaded taper pin with a concave shoulder. Most important Challenges of Friction Stir Welding are application of high temperature materials Tool material selection Development of Tool Materials Tool design and Complex geometries and dissimilar materials.
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. Friction Stir Processing of Materials. The shape of the friction stir tool.
