The aim of this work was to evaluate residual stress levels and mechanical properties of welded joints of Aluminum-Magnesium alloy AA 5083-O using the Friction Stir Welding process.
Aluminum, considered the most frequently used non-ferrous metal in modern industry, combines with various chemical elements with the aim of increasing some properties such as mechanical and corrosion resistance, forming the aluminum alloys.
The traditional processes of fusion welding promote the formation of intermetallic compounds (IMC) of FexAly type, which significantly decrease the joint tenacity [2].

Magnesium alloys are attractive materials for structural applications as they are the lightest commercial alloys which pose highest strength to weight ratio.
The study was carried out with the aim of optimizing the distance between the passes of multi-pass FSP of the AE42 alloy.
As magnesium alloys are easily processed, the load required for FSP is less; hence a medium duty CNC milling machine can be used for FSP of magnesium alloys.
