Abstract

Friction welding is the process in which the heat required for welding is obtained by friction occurs between the ends of the parts to be joined .One of the part to be joined is rotated at a very high speed and the other part is axially aligned with the first one and pressure applied against it. In this study, the effect of welding parameters on hardness of Al alloys weld were investigated. Three levels of Rotational speed, travelling speed & Tilting angle were taken to weld specimen of aluminium alloys. This paper investigates the influence of friction stir welding based on Taguchi method so as to obtain optimum value for hardness. It was found that hardness response displaying a decreasing trend with an increase in the value of Rotational speed. The maximum value of hardness response is at the first level of Rotational speed & second level of Travelling speed & Tilting angle parameters.

Keywords: Taguchi Design, Orthogonal Array, Friction stir welding, traveling speed.
