Feasibility of FSW as Assembly Technology in Aerospace

Feasibility of FSW as Assembly Technology in Aerospace
Summary
Riveting is the best known and most extended technology for airframe component assemblies. Nevertheless, it results in a very inefficient process even when automated since it requires individual drilling, rivet installation, sealant application and inspection plus a significant increase of the assembled set weight. Friction stir welding has demonstrated certain benefits that could be applied to assembly processes of linear profiles and this project aims to evaluate the feasibility and gains when substituting traditional riveting by friction stir welding of the parts.
