Evaluation and Impacts on Mechanical Behavior of Friction Stir Welded Copper 2200 Alloy

Abstract

In the recent years, friction stir welding (FSW) is playing vital role in automobile and aerodynamic industrial applications. Butt joint configuration is the mainstream of FS welding. In this research work, copper alloys are used for analysis and evaluation by FS welding. The endeavor of this work is to find out the achievability of FS welding process by welding pair of copper plates and study the consequences on the physical properties and mechanical characteristics of welded joints. These geometries are used comprehensively in aerodynamic vehicles, in naval vessels, marines. Since of its weak weldability, it is not comprehensively used in automobile industries. To conquer this barrier, weldability analysis is carried out with Cu 2200 copper alloys using a high-speed steel H13 tool. On further attempts, investigations conceded an influence of elevated revolving speed of tools 900 rpm, axial force 5KN, and welding feed 31.25 mm/sec on tensile strength of 254.25 N/mm2, hardness of 451HRB, and impact test of 34 J of copper alloys joint. Vertical milling machine (VMM) is used for conducting experiments. Determining the good tensile strength is main aim of investigation. The end results show that axial load and tensile strength are inversely related, whereas if tool rotating speed and welding velocity increase, the tensile strength increases.
