4. FSW welding
4.1 Parts preparation
Welding is mainly carried out on butt-jointed parts, but other joint configurations are also possible, such as angle or T-joint welding, for example, or overlap welding (figure 11 ). No chamfers are required, simplifying preparation.
Joint accuracy is not critical, and abutment defects of up to a tenth of the thickness to be welded are, for the most part, acceptable. The process is not disturbed, and there is no potential impact on the geometric and mechanical qualities of the finished assembly.
In the case of aluminum alloys in particular, there's no need to strip the parts before welding, and what's more, the oxides...

Most of the data concerning the process can be found at the British Welding Institute, TWI, and the French Welding Institute, IS.
The process is currently the subject of numerous research and development programs financed by companies and institutes, some of which are French (aeronautics, railways, etc.). They cover all aspects of the process: scientific, technological, economic and practical. All...
