ABSTRACT
Friction Stir Welding (FSW) is an innovative welding technology that has made significant inroads in the joining of aluminum alloys. To explore the potential advantages in joining structural steels by FSW, the present study focuses on basic characterization of friction stir welded S235JR plates Microstructure, micro-hardness and tensile properties in terms of the joint efficiency were found 130 % compare to as receive base material (BM) theoretically properties. The study focuses on the mechanisms of microstructure evolution at various regions of the FSW joint, resulting from the effect of strain, temperature and tool interaction on the phase transformations. Hardness of weld zone was higher than the base material Different microstructure zones were revealed by optical microscopy.
