Aircraft skin and stringer elements are typically fabricated from 2xxx and 7xxx series high
strength aluminum alloys. A single friction stir welding (FSW) pass using a specially
designed tool with shoulder/pin diameter ratio (D/d) of 3.20 is used to produce dissimilar T-
butt welds between AA2024-T4 and AA7075-T6 aluminum alloys at a constant travel speed
of 50 mm/min and different rotational speeds of 400, 600 and 800 rpm. The AA2024-T4 is
the skin and the AA7075-T6 is the stringer. Sound joints are produced without macro defects …
