Abstract: Friction stir welding (Fsw) uses anon consumable tool to generate friction heat in the abutting surface, the welding parameter such as rotational speed, welding speed, tool tilt angle and tool pin profile play a major role to produce best quality joint. in this project we select two tool geometries square and triangle and constant tilt angle 2° as well as to three rotational speed 800,1000,1200 rpm and constant welding speed 35mm min.under the above parameters we peformed six specimens at different condition and two kinds of tool geometring (square,triangle) After the tensile test for all specimens it is clear to detect that the Square tool under 1200 rpm and welding speed 30mm min produce the high tensile stress due to heat generation at this condition.
