Abstract
Since its development in ’90, Friction Stir Welding (FSW) had known an important growth,
especially for the hard to weld aluminium alloys. For these FSW
has been shown to produce welds of
high quality with no defects, reduced cost and lower environmental impact when compared to
traditional fusion welding. The process parameters influence on
the connection formation is related.
An experimental program realized
by HZG of FSW, applied on two
aluminium alloys recommended
to be used in the field of civil engineering is presented. Detailed characterisations are presented
aiming to emphasize the performance of the process for the analysed alloys.
