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… Expand
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 rotatingExpand
Dynamics of rotational flow in friction stir welding of aluminium alloys
Abstract Al 1050 and Al 6061 plates with the same thickness were configured one after the other along the welding path. During friction stir welding, the rotating tool traversed from one to the otherExpand
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 deformationExpand
The role of friction stir welding tool on material flow and weld formation
In this investigation an attempt has been made to understand the mechanism of friction stir weld formation and the role of friction stir welding tool in it. This has been done by understanding theExpand
Study on in-situ material flow behaviour during friction stir welding via a novel material tracing technology
Abstract A novel material tracing technology was proposed using ER2319 aluminium alloy welding wire as the tracer material to study the material flow behaviour at different positions of friction stirExpand
Three-dimensional material flow during friction stir welding of AA5083
Abstract Three-dimensional material flow during friction stir welding (FSW) was investigated using a tracer insertion technique. The tracer material is none other than the substrate material used asExpand
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 plasticizedExpand
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-distributedExpand
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 contiguousExpand
The use of plasticine as an analog to explore material flow in friction stir welding
This study investigates plasticine for use as an analog for modeling material flow in friction stir welding of metals. Different colors of plasticine are combined in a weld to aid in flowExpand
