A man-machine interface for friction stir welding (FSW) was proposed that allows a human operator to augment a traditional control system by monitoring and continuously adjusting the parameters of an established welding programme, and hardware and s…

The degradation mechanisms of friction stir welding (FSW) tools made of three tungsten alloys were investigated. Tools were made from 99%W-1%La2O3, 75%W-25%Re and 70%W-20%Re-10%HfC. These were used to make friction stir welds in high strength steel …

As the development and implementation of hydrogen fuel systems gains momentum, the production of containers capable of ensuring optimal conditions for hydrogen transportation and storage has become a focal point across various industry sectors. In t…

The hybrid component of the combination magnesium’s lightness and aluminum’s formability should be useful for energy saving. The welding of dissimilar metallic materials is difficult for their difference in melting temperatures and the formation of …

A tool made from a Co-based alloy strengthened by precipitation of an intermetallic Co3(Al,W) gamma phase with an L12 structure was developed for friction stir welding of high-softening-temperature materials, such as a 0.45%C steel, and the tool wea…

Thermomechanical modelling of the friction stir butt welding process in AA 5083-H18 aluminium alloys was undertaken using a CFD (computational fluid dynamics) code to describe the steady state, and simulated temperature profiles were compared with t…

Aluminum 6xxx extrusions are commonly joined with either friction stir welding (FSW) or fusion welding into large-sized assemblies. The assemblies are typically deployed to service in as-welded condition. Mechanical performance of naturally aging we…
