Computational Modeling of Friction Stir Welding
Friction stir welding (FSW) is a relatively new, solid-state, metal joining process invented by Wayne Thomas et al. at the Welding Institute of England (now TWI) in 1991 [1.] A FSW butt weld is made by following the joint-line of two butted pieces of material with a rotating tool while applying a significant down-force through the tool. Heating is provided at or near the tool-work interface by ...
متن کاملThermal Analysis of Friction Stir Welding with a Complex Curved Welding Seam (TECHNICAL NOTE)
Friction stir welding (FSW) can be defined as a green technology, because the consumption of energy during this process is less than other welding methods. In addition, during the process there is no gas, filler material or other consumables. It should be noted that, complex curved shapes are now commonly used in different industries in a bid to have lightweight structures. According to the abo...
متن کاملFinite element modeling of friction stir welding—thermal and thermomechanical analysis
Friction stir welding (FSW) is a relatively new welding process that may have significant advantages compared to the fusion processes as follow: joining of conventionally non-fusion weldable alloys, reduced distortion and improved mechanical properties of weldable alloys joints due to the pure solid-state joining of metals. In this paper, a three-dimensional model based on finite element analys...
متن کاملThermal modeling of friction stir welding in a moving coordinate system and its validation
A three-dimensional heat transfer model for friction stir welding (FSW) is presented in this paper; a moving coordinate is introduced to reduce the difficulty of modeling the moving tool. Heat input from the tool shoulder and the tool pin are considered in the model. The finite difference method was applied in solving the control equations. A non-uniform grid mesh is generated for the calculati...
متن کاملModeling of Friction Stir Welding of AL7075 Using Neural Networks
Friction stir welding (FSW) is a solid state welding process, which is used for the welding of aluminum alloys. It is important to note that the mechanical properties of the FSW process depends on various process parameters, such as spindle speed, feed rate and shoulder depth. Two different tool materials, such as High speed steel (HSS) and H13 are considered for the welding of Al 7075. The pre...
