The Effect of Tool Geometry on Material Flow Behavior of Friction Stir Welding of Titanium Alloy
Article history: Received 1.11.2012 Received in revised form 10.12.2012 Accepted 10.12.2012 Based on the RNG k-ε model, the finite volume model of friction stir welding of Ti6Al4V alloy is established by ANSYS FLUENT software. The effect of rotational tool geometry on titanium alloy flow behaviour is exhibited. The results of numerical simulation show that the flow direction of material near th...
متن کاملMaterial Flow Visualization in Friction Stir Welding via Particle Tracing
This work deals with the modeling of the material flow in Friction Stir Welding (FSW) processes using particle tracing method. For the computation of particle trajectories, three accurate and computationally efficient integration methods are implemented within a FE model for FSW process: the Backward Euler with Substepping (BES), the 4-th order Runge-Kutta (RK4) and the Back and Forth Error Com...
متن کاملTool Geometry for Friction Stir Welding—Optimum Shoulder Diameter
The most important geometric parameter in the friction stir welding (FSW) tool design is the shoulder diameter, which is currently estimated by trial and error. Here, we report a combined experimental and theoretical investigation on the influence of shoulder diameter on thermal cycles, peak temperatures, power requirements, and torque during FSW of AA7075-T6. An optimum tool shoulder diameter ...
متن کاملCoupled Eulerian-Lagrangian (CEL) Modeling of Material Flow in Dissimilar Friction Stir Welding of Aluminum Alloys
In this work, the finite element simulation of dissimilar friction stir welding process is investigated. The welded materials are AA 6061-T6 and AA 7075-T6 aluminum alloys. For this purpose, a 3D coupled thermo-mechanical finite element model is developed according to the Coupled Eulerian-Lagrangian (CEL) method. The CEL method has the advantages of both Lagrangian and Eulerian approaches, whic...
متن کاملModeling of heat generations for different tool profiles in friction stir welding: study of tool geometry and contact conditions
In this work, improved heat generation models are developed for straight and tapered shoulder geometries with different tool pin profiles in friction stir welding. The models are developed considering the welding process as a combination of the pure sliding and the pure sticking conditions. From the results, the amount of heat generation is directly proportional to the number of edges in the pi...
