Developing a Mathematical Model to Predict Tensile Properties of Friction Welded AISI 1035 Grade Steel Rods

Abstract:

In this work, frictions welding of AISI 1035 grade steel rods of 12 mm diameter were investigated with an aim to predict the value of tensile properties. Welds made with various process parameter combinations were subjected to tensile tests. Here, the three factors, five levels, central composite, rotatable design matrix are worn to limit the number of experiments. The mathematical models were developed by response surface method (RSM). The adequacies of the models were checked through ANOVA technique. From developed mathematical models, ultimate tensile strength (UTS) of the joints can be predicted by means of 95 percent confidence level. The integrity of the joints has been investigated using optical microscope.
