Optimizing the friction welding parameters to attain maximum tensile strength in AISI 1035 grade carbon steel rods

In this work, 12 mm diameter AISI 1035 grade steel rods are friction welded with an aim to optimize the process parameters. The joints are made with various process parameter combinations (incorporating ANOVA methods) subjected to tensile test. The empirical relationships are established to predict the ultimate tensile strength, notch tensile strength, and % of elongation of the welded joints. The consistency of the model has been checked. The tensile properties, micro-hardness, microstructures, SEM, and the EDAX of the welded specimens have been studied and presented in this study. (C) 2014 Elsevier Ltd. All rights reserved.
