Effects of tool rotation speed and tilt angle on friction stir welding of Al- 6075

Abstract

Friction stir welding (FSW) is a new technology of welding the aluminium alloy profile plate. In conventionally welding technique toxic and hazardous gases emits. But FSW we didn?t get such toxic gases and it is energy efficient. There are few parameter which effects FSW like tool tilt angle, tool rotational speed, tool shape design, and feed rate. In this paper impact of tool tilt angle and tool rotational speed on tensile strength and hardness is discussed.
