Abstract

Engineering materials require the joining of various members to form usable structures. Among the commonly used joining methods are riveting and fusion welding. Riveting has a challenge of low joint tensile strength while some important materials cannot be welded by the fusion method. To solve the fusion welding challenge, the welding institute invented a solid-state metal joining technique called friction stir welding for joining aluminium alloys. Friction stir welding has however gained remarkable attention for application to metals hard to weld by fusion. This review paper analyses applications of friction stir welding on hard-to-weld metals by fusion. The selected metals include steels, magnesium, copper, titanium and aluminium alloys.

Keywords: FSW, Hard-to-Weld Materials.
