In this research, the effects of parameters include tool rotational and traverse speeds were investigated on heat generation and material flow during friction stir welding of Ti-6Al-4V alloy with computational fluid dynamics (CFD) method. Simulation results showed that with increasing of tool rotational and decreasing tool traverse speed, the more frictional heat generates which causes formatio...

The objective of this study was to develop a numerical model for the prediction of temperature distribution, effective plastic strain distribution, and especially material flow in friction stir welding of copper plates. The DEFORM-3D software was used by incorporating a lagrangian incremental formulation. Threedimensional results of the material flow pattern which were extracted using the point...

The development of Friction Stir Welding (FSW) has provided an alternative approach for producing high-quality welds, in a fast and reliable manner. This study focuses on the mechanical properties of the dissimilar friction stir welding of AA6061-T6 and AA7075-T6 aluminum alloys. The FSW process parameters such as tool rotational speed, tool traverse speed, tilt angle, and tool offset influence...

Friction Stir Welding (FSW) is a recently-developed technique where metals are joined together through mechanical stirring. FSW, often performed by robotic welders, is being used in an increasing number of industries such as aerospace, maritime and transportation. FSW has proven to be very effective and has replaced fusion welding and riveting in a number of manufacturing processes. In order to...

Friction stir welding, a solid state innovative joining technique, is widely being used to join aluminium alloys for aerospace, marine automotive and many other applications of commercial importance. FSW trials were carried out using a vertical machining centre (VMC) on AA6061 alloy.

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 ...
