DAAAM INTERNATIONAL SCIENTIFIC BOOK 2015 pp. 249-266 Chapter 22 A CRITICAL REVIEW OF FRICTION STIR WELDING PROCESS VERMA, S. M. MISRA, J.P. Abstract: Friction stir welding (FSW) is a permanent type solid state joining process which is increasing rapidly for joining different metal alloys and non-metals in manufacturing industries especially aerospace, marine, spacecraft, automotive, etc. In present scenario the welding of metal alloys are replaced by FSW owing to its unique features ove r fusion welding processes, i.e. reduced porosity defect, reduced heat affected zone (HAZ), no requirement of shielding gas, ecofriendly, reduced distortion, etc. In this chapter, a critical evaluation of critical aspects of friction stir welding namely process principle, metallurgical and mechanical aspects; effect of prehea ting and nano-particle inclusion have been discussed . Difficulties and other issues related to FSW are also addressed to provide a guideline to global research community to carry out extensive research in this field. Key words: Solid-state welding, friction stir welding, preheating, quenching, nano - particle inclusion Authors´ data: Verma, S[hubham], M[eenu] Misra, J[oy] P[rakash], Mechanical Engineering Department, National Institute of Technology Kurukshetra , India, joyprakash.misra@ .
