Optimization of friction welding parameters on aluminium 7068 alloy

Abstract In present scenario, the role of welding techniques was played an essential to any industrial applications. The demands of most economical and high productive weld have been increased. It was satisfied by Friction Welding (FW) technique. It was used to join ferrous and nonferrous metals. In the present work, to discuss about friction welding of aluminium 7068 alloy. The tensile strength was measured with respect to the input factors such as rotational speed, friction and forging pressure. The parametric effect and best possible solutions were done by Response Surface Methodology (RSM). The intercept of factors and its effects have been discussed through three dimensional surface plot analysis and variance test.
