Most metallic alloys that are not easily joined by conventional fusion welding are usually joined by friction stir. on this basis, friction stir welding has seen a wide application in different industry. Friction stir welding is complex phenomena having connected physical phenomena. However, it is usually difficult to theoretically develop a system of governing equation to analyze friction stir welded joint, due to the three-dimensional nature and complex geometry. Also, the experimental techniques are often time consuming and costly. Meanwhile, numerical analysis has been introduced to overcome these problems. This study presents a straightforward perspective to friction stir welding (FSW) of AISI 4340 steel alloy numerical modeling and simulation. A three-dimensional heat transfer model for FSW was presented, the coordinate system was considered as a moving one, while the tool axis is fixed. Stationary convection-conduction was adopted to solve heat transfer problem. The Heat generated between the interface between the tool pin the work piece was simulated using model created in COMSOL Multiphysics software V 4.0.
