Analysis of friction welding parameters on the mechanical metallurgical and chemical properties of AISI 1035 steel joints

Abstract In this present work, the analysis of process parameters on mechanical, metallurgical and chemical properties of American Iron and Steel Institute (AISI) 1035 steel rods of 12 mm diameter joints produced by friction welding is analyzed. The joints made with various process parameter combinations are subjected to tensile tests, hardness test and cyclic potentiodynamic polarization tests. The properties such as tensile strength, notch tensile strength, yield strength, % elongation, and vickers’s hardness, fully deformed zone (FDZ), flash formation and pitting corrosion has been analyzed for high level and low level process parameters. The optimized process variable is obtained by using Response Surface Methodology (RSM). The integrity of the welds has been investigated using high magnification optical microscopy. The fracture surface of the tensile test specimen is analyzed by using Scanning Electron Microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDAX).
