What is Friction Stir Welding (FSW)? - Process and

The mechanical properties of friction stir welded aluminium alloys have been proven better than those found with other welding processes,such as arc welding.With regard to the mechanical properties of FSW,this process typically has three main microstructural regions; a weld nugget,a thermo-mechanically affected zone (TMAZ) and a heat Transformation in Stir Zone of Friction Stir WeldedTransformation in Stir Zone of Friction Stir Welded Carbon Steels with Different Carbon Contents Ling CUI,1)Hidetoshi FUJII,Nobuhiro TSUJI,2) Kazuhiro NAKATA,Kiyoshi NOGI,1) Rinsei IKEDA3) and Muneo MATSUSHITA3) 1) Joining and Welding Research Institute,Osaka University,11-1 Mihogaoka,Ibaraki,Osaka 567-0047 Japan.Transformation in Stir Zone of Friction Stir Welded Carbon Transformation in Stir Zone of Friction Stir Welded Carbon Steels with Different Carbon Contents Ling Cui 1) ,Hidetoshi Fujii 1) ,Nobuhiro Tsuji 2) ,Kazuhiro Nakata 1) ,Kiyoshi Nogi 1) ,Rinsei Ikeda 3) ,Muneo Matsushita 3)
