Evaluation and Impacts of Tool Profile and Rotational Speed on Mechanical Properties of Friction Stir Welded Copper 2200 Alloy

Abstract

Friction stir welding has been studied intensively in recent years due to its importance in Automobile industrial applications. The majority of these studies have been based on butt joint configuration. In my present research work and Evaluation, Cu 2200 copper alloys are welded by friction stir welding .The aim of this work determine the feasibility to weld two pieces of Copper Plates by friction stir welding process and study the effect on the mechanical and physical properties of welding joints. These geometries are used extensively in aerospace vehicles, in nautical vessels, pressure vessels, and automobile industries and not widely used because of its poor weldebility. To overcome this barrier, weldebility analysis of Cu 2200 copper alloys with high speed steel H13 tool has been investigated. An attempt has been made to investigate and evaluate the influence of the rotational speed of the tools, the axial force and welding speed on tensile strength of Cu 2200 copper alloys joint. The experiments were conducted on a Vertical milling machine. The main focus of investigation is to determine good tensile strength. Response surface methodology is chosen to design the optimum welding parameters leading to maximum tensile strength. The result shows that axial force increases, tensile strength decreases. Whereas tool rotational speed and welding speed increase, tensile strength increases.
