An Overview of Friction Stir Welding Process and Parameters of Aluminium Alloys

The widespread application of aluminium and its alloys in the field of engineering, aerospace, automobiles etc. has made it an important material which is being extensively explored. Various welding techniques have been used to weld aluminium and its different alloys. Friction stir welding is a new process and a promising solid welding technology which is easily overcoming the disadvantages of the traditional welding techniques. The present review paper which constitutes the information explored through various online resources on friction stir welding process of different aluminium alloys and also give briefs of the results of various studies related to the effect of process parameters such as tool rotation, tool pin shape etc. on the mechanical properties such as tensile strength, hardness, fatigue strength, impact strength etc and microstructure of the welded joints of similar and dissimilar aluminium alloys.
