1. INTRODUCTION Welding is a fabrication process that joins materials by causing coalescence, usually done for metals or thermoplastics. This is generally done by melting the work pieces and adding a filler material to form a pool of molten material which cools down and develop into a tough bonding, with pressure at times used in conjunction with heat, or by itself, to produce the weld. This is in contrast with brazing and soldering process, which is done by melting a low-melting-point material and used to fill the gap of parent material pieces.
In late 1991 a very novel and potentially world beating welding method was conceived at The Welding Institute(TWI). The process was named as friction stir welding (FSW), and TWI filed for world-wide patent[1]. Consistent with the more conventional methods of friction welding, which have been practiced since the early 1950s, the weld is made in the solid phase, that is, no melting is involved. FSW uses a rotating tool to generate the necessary heat for the process. Since its invention, the process has received world-wide attention and today two Scandinavian companies are using the technology in production, particularly for joining aluminium alloys. Also, FSW is a process that can be automated. It is also a cleaner and more efficient process compared to conventional techniques FSW process can be used with different alloy materials, aluminium either as parent material or alloy material. Few researchers studied the optimization of machining parameters on Ti-6Al-4V material by using hgh speed machining process which is a base process for Friction stir welding[2,3]. Gurmeet sing et. al. found that friction stir welded joints have superior mechanical properties as compared to TIG welded joints. From the micro structure analysis it was observed that fine and equiaxed grains were observed in the friction stir welded joints and coarse grains were observed in TIG welded joints[4]. The process can also be experimented in manufacturing of cryogenic vessels[5].
2. WELDING PROCESSES
2.1. Friction Stir Welding Process
2.1.1. Working Principle In friction stir welding (FSW) a cylindrical, shouldered tool with a profiled probe is rotated and slowly plunged into the joint line between two pieces butted together. The parts have to be clamped together in contact onto a backing plate to prevent the abutting joint faces from being forced apart. Frictional heat is generated between the work piece material and welding tool which has a property of wear resistant. This heat produced by the friction causes the latter material to soften without reaching the melting point of the parent material and allows traversing of the tool along the weld line. The maximum temperature reached is of the order of 0.8 of the melting temperature of the material. The plasticized material is transferred from leading edge of the tool probe to the trailing edge and is forged by the intimate contact of the pin profile and the tool shoulder. It leaves a solid phase bond between the two pieces[6,7]. The vertical milling machine used for the experiment shown in figure 1.
