Modeling and Analysis of Friction Stir Welding and Underwater Friction Stir Welding of Aluminium Alloy: A Review

摘要

The welding of aluminium and its alloys was a great challenge for researchers and technologists till 1991. Friction stir welding (FSW), a relatively new solid state joining process was first patented in 1991 by Thomas et. al. from 'The welding Institute (TWI), England. Later its application found in various industries like aerospace, marine, automobile, etc. due to its high quality joints. The technique is energy efficient, ecofriendly and versatile too. In this review article, the modeling and analysis of friction stir welding and underwater friction stir welding (UFSW) of aluminium alloy are addressed. Commonly used method for modeling and analysis of welded joints such as Taguchi method and Response surface method (RSM) are considered for the review. Finally an attempt has been made to compare UFSW welded joints with FSW welded joints.
