Sensitivity analysis of friction welded AISI52100 grade carbon steel rods

In this work, friction welding of AISI 52100 grade carbon steel rods of 12mm diameter was investigated with an aim to analyze the sensitivity of Tensile strength for the process parameter. Welds are made with various process parameter combinations using ANOVA design matrix which were subjected to tensile tests. The Ultimate tensile strength of the welded joints has been reported. A microstructure analyses were carried out to acquire the joint efficiency. The various zones of the microstructure have been shown in the optimized condition.
