Joining of the 5083 aluminum alloy using the bobbin tool friction stir welding technique
Conventional fusion welding of aluminum alloys results in coarse-grained structure, inevitable defects, and significant softening in the welding region. Friction stir welding with bobbin tool is a technique of friction stir welding method that has a great potential for developing applications of friction stir welding method in marine, aerospace, and automotive industries due to having an extra ...

متن کاملModelling of friction stir welding for robotic implementation
A three-dimensional numerical model is used to simulate the Friction Stir Welding (FSW) process using the computational fluid dynamics package ‘FLUENT’. Two mechanical models: the Couette and the Visco-Plastic fluid flow models for Al-6061-T6 were simulated. The simulation results are compared to experimental data for Al 6061-T6 welded at high rotational (1500–5000 rpm) and travel speeds rangin...
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 کاملDesign of Friction Stir Welding Tool for Avoiding Root Flaws
In order to improve material flow behavior during friction stir welding and avoid root flaws of weld, a tool with a half-screw pin and a tool with a tapered-flute pin are suggested. The effect of flute geometry in tool pins on material flow velocity is investigated by the software ANSYS FLUENT. Numerical simulation results show that high material flow velocity appears near the rotational tool a...
