Abstract
Friction stir welding is a solid state joining process mostly used to weld aluminium alloys which are difficult to weld by conventional fusion welding processes. Apart from this, its ecofriendly and versatile quality makes friction stir welding stand unique from other traditional welding. As the joining process in friction stir welding is done below the melting point of base metal, it can be considered as the most significant development in metal joining world. It is essential to measure the amount of heat generated and temperature distribution during friction stir welding as it had direct influence over the mechanical properties of the weld zone and heat affected zone. However, it is difficult to measure temperature in the weld zone due to the plastic deformation produced non-consumable rotating tool. In this review article, development in the analysis of heat generation and temperature distribution are addressed. The complexities in experimental analysis lead to numerical analysis in the measurement of temperature histories during friction stir welding and hence more emphasis has been given to the latest developments in numerical analysis of friction stir welding process.
