Friction stir welding is gaining significance in typical joining applications day by day. Modeling and simulation of FSW has been a great challenge due to the complexity of the process. We are initiating an effort to review various modeling and simulation techniques mentioned in literature and to find the future scope and possibilities of new techniques.
In present study, the effect of heat treatment after friction stir welding dissimilar welds T6-7075 and T4-2024 aluminum alloys were investigated. Friction stir welding was performed at a constant rotation speed of 1140 rpm and welding speed 32 mm/min. After welding samples are taken under various heat treatment processes at different aging temperature and time period. Microstructural observati...
Friction stir welding is a relatively new solid state joining process, which is suitable for welding similar and dissimilar materials. The present research work concentrates on the effect of tool rotational speed on the tensile, microstructural properties and microhardness of the friction stir welded joints of different grades of austenitic stainless steel sheets. Four different tool rotationa...
Friction stir welding (FSW) is a joining process where the regulation of some technological parameters, like machining forces and tool velocities, is essential to ensure the required product quality. Therefore industrial robots are often equipped with force sensors in order to have a monitoring of the interaction forces between the rotating tool and the sheets metal. Alternatively a mathematica...

This paper focuses on Friction Stir Welding (FSW), a fairly recent technique, invented by The Welding Institute (TWI) in 1991, that utilizes a non-consumable rotating welding tool to generate frictional heat and plastic deformation at the welding location; thereby, affecting the formation of a joint while the material is in the solid state. In particular, FSW can be used to join high-strength a...
