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

Characterization of tool wear and weld optimization in the friction-stir welding of cast aluminum 359+20% SiC metal-matrix composite
G. J. Fernandez,Lawrence E Murr +1 more
TL;DR: In this paper, the authors show that the weld zone becomes more homogeneous for efficient welding with self-optimized tools, and there is a reduction in the welding zone grain size due to dynamic recrystallization, which facilitates the solidstate flow.

Characterization of aluminum/steel lap joint by friction stir welding
TL;DR: In this article, the effects of the welding parameters on the joint strength were discussed metallographically based on observations with optical and scanning electron microscopes, showing that the welding strength depended strongly on the depth of the pin tip relative to the steel surface.
