Abstract

Friction stir welding -FSW- is a new process of joining AA7020- T53 aluminum alloy sheet. There are few parameters which effects of FSW such as spindle speed, feed rate, tool design and tool tilt angle. In this search, the effect of tool rotational speed (spindle speed) and travel speed (feed rate) on mechanical properties are discussed. The FSW technique was performed using three different of rotational speeds and three different traverse speeds, while other parameters are kept constant to compare between joints. It was found that the best mechanical properties can be obtained from using high spindle speed and high feed rate. The ultimate tensile strength increases approximately 25% while the yield stress and elongation increases approximately 19% and 57% respectively, when used spindle speed (900r.p.m) and feed rate (50 mm/min).
