Friction Based Welding Technology for Aluminium

摘要

The friction processes include rotary friction welding, friction surfacing and friction stir welding (FSW). The principles involved are described. Friction stir welding (FSW) has had a revolutionary effect in certain welding applications, so that now FSW is the first choice joining method for the fabrication of the aluminium alloy external fuel tanks for aerospace and for other extreme applications. This paper describes FSW tool evolution, and future applications.
