It utilizing a pivoting apparatus to create frictional heat that makes materials of the segment be welded to mellow without achieving the dissolved point and enable the device to move along the weld line. Plasticized materials are exchanged from the trailing edge of the instrument test to main edge, leaving a strong stage bond between the two sections. Friction stir welding from nut and bolts to applications surveys the essentials of the procedure and how it is utilized as a part of modern applications. Key Words: Friction, Alloy, Tensile 1. INTRODUCTION Friction stir welding (FSW) is a process of joining work piece without softening the metal and it uses non consumable tool. Heat is delivered by the erosion between the non consumable tool and work piece material, which stir up a locale close to the friction stir welding tool. While the devise is crossed along the joint line, it mechanically intermixes the two bits of metal, and produces the hot and mellowed metal by mechanical weight, which is connected by the tool, much like joining dirt, or better. It is basically utilized on created and expelled aluminium and especially for structure which required high weld quality. 2.

Cut the required size of the work piece to be weld. 2. Place the work piece on the machine work bench. 3. The selected friction stir welding tool has to be fit in the machine spindle. 4. In friction stir welding machines setting the rotation speed (w), axial force (F) and welding speed (v) 5. Welding process is started from one end to another end of the work piece. 6. Repeat the same procedure for other work pieces. 7. Cut the specimen according to the standard size for testing.
