Abstract

Friction welding is a solid state welding process that generates heat through mechanical friction between wok pieces in a relative motion to one another with the addition of lateral force called “upset” to plastically displace and fuse the materials. The purpose of this work is to join and assess the development of solid state joints of similar AA6063T6 grade aluminum alloy materials and studying the effect of rotational speed and size effects on the mechanical behaviour of welded joints. Apart from being a very efficient heat source friction provides an effective cleaning action. Various foreign inclusions, surface oxides and absorbed films that oppose formation of bonds are destroyed & removed by abrasion produced by friction. Hence the bonding or welding is stronger. Finally it is concluded that the rotational speed and size of the material strongly influencing the mechanical properties of the welded joints.
