Parametric Optimization of Friction Stir welding using Different Tool Profiles: A Review

Abstract

the parameters like tool rotational speed, tool profile, depth of cut, feed etc. are affecting the properties of welded joints. Amongst the emerging new welding technologies, friction stir welding (FSW), invented and established by The Welding Institute (TWI) in 1991, is used frequently for welding of high strength aluminium alloys such as AA6061, AA6082, etc. which are difficult to weld by conventional fusion welding techniques. Friction welding (FW) is a collection of a series of friction-based solid state joining processes which can produce high quality welds of different components with either similar or dissimilar materials and has been attracting increasing attention. The project aim is to weld two plates of AA 6082 using different tool profiles and to optimize the strength of joint.
