Review: friction stir welding tools
TLDR
Friction stir welding (FSW) is a widely used solid state joining process for soft materials such as aluminium alloys because it avoids many of the common problems of fusion welding as mentioned in this paper.Abstract:
Friction stir welding (FSW) is a widely used solid state joining process for soft materials such as aluminium alloys because it avoids many of the common problems of fusion welding. Commercial feasibility of the FSW process for harder alloys such as steels and titanium alloys awaits the development of cost effective and durable tools which lead to structurally sound welds consistently. Material selection and design profoundly affect the performance of tools, weld quality and cost. Here we review and critically examine several important aspects of FSW tools such as tool material selection, geometry and load bearing ability, mechanisms of tool degradation and process economics.read more

Process Force Reduction During Robotic Friction Stir Welding of Aluminum Alloys with Reduced Tool Aspect Ratios
TL;DR: In this paper, the scaling effects during FSW with reduced tool diameters at adjusted process parameters, in order to keep the stress conditions in the shear layer constant and hence counteract the compromised mechanical loadability of the scaled tools, are evaluated.

Effect of rotational speed and copper interlayer on the mechanical and fracture behaviour of friction stir spot welds of 5754 aluminium alloy
TL;DR: In this article , the authors evaluated the mechanical behavior of 5754 aluminium sheets jointed by friction stir spot welding (FSSW) and found that without an interlayer, lower and intermediate rotational speeds lead to higher mechanical strength under tensile shear tests compared to riveted assembly.

I and i
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
