Friction welding (FW) means a solid-state welding process that is extensively used due to its various beneficial points such as it can be used with numerous materials, develops the low heat input, easy for manufacturing, and environmentally friendly. Friction welding process parameter values such as friction pressure, friction time, forging pressure, forging time, and rotation speed have great influence on strength of the joints. The main objective of this research is to understand the effects of friction welding parameters on the joint characteristics of aluminum semi solid casting 7075 to AISI 1018 low carbon steel with 10 mm diameters and 100 mm length. The experimental result revealed that rotation speed and forging pressure affected the tensile strength of welded joints with level of significance. With increasing rotation speed and forging pressure, the tensile strength of welded joints increased. Microstructural characterization of FDRZ provided a complete characterization of dynamic recrystallization. The grains sizes were refined with increasing rotation speed while the tensile strength of welded joints increased accordingly.
