Tensile Strength and Microstructure of Rotary Friction-Welded Carbon Steel and Stainless Steel Joints

Due to the different properties of materials, fusion welding dissimilar metals may be difficult. Structural irregularities form as a result various phase transformations during welding. Solid-state welding, opposed occurs below melting temperature. As and solidification phenomena that happen in solid-state is expected reduce potential for transformation. This paper describes use rotary friction technique join carbon steel 304 stainless steel. The purpose this work investigate characteristics (RFW) when joining steels with contents. Experiments were carried out on RFW low- medium-carbon investigation was using Taguchi method experimental design. joints’ tensile strengths microstructures evaluated. parameters had greatest influence results identified. combination resulting strength also suggested. A microstructural examination weldment revealed mechanical mixing interlocking.
