Demands for improved productivity, efficiency, and quality challenges to the welding industry. As materialsbecome ever more sophisticated in their chemical composition to provide ever-better functionally specific properties, amore complete and precise understanding of how such materials can be joined for optimal effectiveness. In thisresearch study paper, Mild Steel and Stainless Steel 304 materials were used, due to their utilization and capabilities ofthese materials in the industry. The research study considers the analysis of Temperature, Time for weld, Heataffected zone in rotary friction welding joint. After rotary friction welding sample preparation, the tensile test hasbeen carried out for examine the strength of the weld (breaking, ultimate, yield strengths).
