Friction Stir Welding and Processing
Rajiv S. Mishra,Zongyi Ma +1 more
TL;DR: Friction stir welding (FSW) is a relatively new solid-state joining process that is used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding as discussed by the authors.

Friction stir welding of aluminium alloys
TL;DR: A comprehensive body of knowledge has built up with respect to the friction stir welding (FSW) of aluminium alloys since the technique was invented in 1991 is reviewed in this article, including thermal history and metal flow, before discussing how process parameters affect the weld microstructure and the likelihood of entraining defects.

Microstructure, mechanical properties and residual stresses as a function of welding speed in aluminium AA5083 friction stir welds
TL;DR: In this article, the results of microstructural, mechanical property and residual stress investigations of four aluminium AA5083 friction stir welds produced under varying conditions were reported, and it was found that the weld properties were dominated by the thermal input rather than the mechanical deformation by the tool.
Journal ArticleDOI
Cross-sectional mapping of residual stresses by measuring the surface contour after a cut
TL;DR: In this paper, a part is cut in two, and the contour, or profile, of the resulting new surface is measured to determine the displacements caused by release of the residual stresses.
