Mathematical Methods and Systems in Science and Engineering Study of Friction Stir Welding Technique as a Solid-State joining of Metallic Plates Mohd Anees Siddiqui, S.A.H. Jafri, Shahnawaz Alam Department of Mechanical Engineering, Integral University Lucknow, INDIA Abstract- Through this paper an attempt is made to study and review a special welding technology of friction stir welding (FSW) which is a solid-state joining on the basis of available literature related to friction stir welding. Friction stir welding is a joining method adopted for joining of two p lates which are applied with compressive force by using fixtures on the work table. FSW process is governed by several process parameters such as tool geometry, joint design and process speed which are discussed in the paper. Quality and environmental aspects regarding friction stir welding are discussed. The major applications of FSW in the field of aerospace, shipbuilding and automotive are also discussed with reference to the several technical reports from FSW machine manufacturers. Keywords—Friction stir welding, process parameters, tool geometry, welding parameters. As a result of this process a joint is produced in ‘solid state’. Because of various geometrical features of the tool, the I. INTRODUCTION material movement around the pin can be quite complex [1]. During FSW process, the material undergoes intense plastic Friction stir welding FSW is one of the
