<abstract xmlns="http://www.w3.org/1999/xhtml"><p> The main aim of this investigation is to produce a welding joint of higher strength than that of base metals. Composite welded joints were produced by friction stir welding process. 6061 aluminum alloy was used as a base metal and alumina particles added to welding zone to form metal matrix composites. The volume fraction of alumina particles incorporated in this study were 2, 4, 6, 8 and 10 vol% were added on both sides of welding line. Also, the alumina particles were pre-mixed with magnesium particles prior being added to the welding zone.

Friction stir welded joints containing alumina particles were successfully obtained and it was observed that the strength of these joints was better than that of base metal.
