One of the advantages of friction stir welding is that no filler material is required to make a weld. However, this can also be disadvantageous, as additional considerations are required to overcome issues with component ‘fit up’ and alignment in production. Adding material to the weld can aid production issues and could also be used to alter component properties and add features.

Trials have shown that it is not only possible to add material to a weld using the stationary shoulder friction stir welding (SSFSW) technique but also to change the form of this additional material into a different geometry. This technique is called ‘AdStir’.
