Abstract Material flow in friction stir welds has been visualised using embedded marker materials. The fidelity of the visualisation technique has also been demonstrated. Results from the flow visualisation show that the friction stir welding process can be roughly described as an in situ extrusion process wherein the tool shoulder, the weld backing plate, and the cold base metal outside the weld zone form an ‘extrusion chamber’ which moves relative to the workpiece. Deviation from this… 

Visualization of the material flow in AA2195 friction-stir welds using a marker insert technique

The material flow in solid-state, friction-stir, butt-welded AA2195-T8 was investigated using a marker insert technique (MIT). Markers made of AA5454-H32 were embedded in the path of the rotating

3D Material Flow in Friction Stir Welds

This study reveals the material flow that occurs as a function of position across a friction stir weld through an analysis of the deviations between the observed orientations of the shear deformation

Analysis of Tool Feedback Forces and Material Flow during Friction Stir Welding

An innovative heuristic force model has been developed to characterize material flow induced by the Friction Stir Welding (FSW) process. When the rotating weld tool travels inside the plasticized

A WELD MARKER TECHNIQUE FOR FLOW VISUALIZATION IN FRICTION STIR WELDING

Experimental techniques have been developed to allow the investigation of metal flows during friction stir welding. The techniques are based on the use of a marker material that is re-distributed

Material flow and intermixing during dissimilar friction stir welding

Abstract Material flow and intermixing during dissimilar friction stir spot welding and friction stir seam welding are investigated. During friction stir spot welding, a ribbon of contiguous

Material-flow behavior during friction-stir welding of 6082-T6 aluminum alloy

Material-flow behavior during friction-stir welding of 6082-T6 aluminum alloy has been visualized by marker insert technique. Four stacked layers were evolved in welding nugget zone (WNZ) in the
