The mechanical properties of friction stir butt welded joints of Aluminium 6061-T6 sheets under oblique loading was experimentally investigated. Six types of test specimens with different oblique butt welding angles were used for tensile test which is subjected to withstand the fixed directional loading. The effect of oblique loading on the tensile strength of the friction stir butt welded structure has been studied. Aluminium 6061-T6 is a solution heat treated then artificial aged aluminium alloy contains Magnesium and Silicon as its major alloying elements exhibits good mechanical properties and weldability. This alloy regularly used in the construction of structural components such as aircraft wings and fuselages, automotive chassis and welded widely by the TIG and MIG welding processes. Friction stir welding is a solid state welding process overcomes fusion welding by means of solidification of molten metal. Chemical properties tests has been done to check the properties of parent metal after welding. Non destructive tests has been performed to test the quality of welds.
