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

Wear Inducing Phase Transformation of Plasma Transfer Arc Coated Tools during Friction Stir Welding with Al Alloy
TL;DR: In this paper, the PTA coating was used with stellite 1 powders (Co-based) to coat on the head of a SKD61 stirring tool (SKD61-ST1) in order to investigate the wear performance and phase transformation after FSW.

Shoulder Related Temperature Thresholds in FSSW of Aluminium Alloys.
TL;DR: In this article, the heat generation in FSSW of aluminium alloys, was assessed by producing bead-on-plate spot welds using pinless tools, and it was found that for rotational speeds higher than 600 rpm, the main process parameter governing heat generation is the tool diameter.

Mathematical Model for Friction Stir Lap Welded AA5052 and SS304 Joints and Process Parameters Optimization for High Joint Strength
TL;DR: In this article , a log-linear regression analysis was applied to formulate an empirical correlation between the process parameters and shear strength, and the achieved joint strength was 3.46 kN that is 70% of the base aluminium metal.

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.
