Abstract
The FSSW is a well-known technology used to obtain joints in overlap configuration. It was developed by Mazda Motors Corporation in partnership with Kawasaki Motors Corporation in 2001. The weld is performed by a rotating tool, composed of two cylindrical geometric features named pin and shoulder. The tool plunges into the sheets, in overlap configuration, at a given rotational speed until the shoulder reaches a defined depth in the upper sheet. In this study, FSSW joints of AA6060-T5 in sheets 3,2 mm thick were produced to assess the effect of welding parameters on plunge force, temperature and joint strength. Three levels of rotational speed and dwell time were defined using a DOE factorial complete analysis that led to a L9 orthogonal matrix. For each welding configuration four samples were produced, one for microstructural assessment and three for mechanical tests. The results showed that the dwell time proved to be a determining factor in the strength of the welded joint. Temperature and plunge force are strongly affected by the welding parameters and their assessment give important insight into the welding development.
