Notes:
The current research has assessed the correlation between welding parameters and corrosionbehaviour for friction stir welded 6056 aluminium alloy. Different thermal treatments and weldingparameters were considered. For the welding parameters studied in this project, the data stronglyindicate that sensitivity to corrosion is linked to the welding parameters employed. Substantialdifferences were found for the higher and lower speed welding parameters, with the lower speedparameters appearantly resulting in less corrosion resistance. The most widespread form ofcorrosion observed was pitting; however, intergranular corrosion (IGC) was also seen. While theT78 thermal treatment appears to decrease the corrosion resistance of the parent alloy, the weldregion tends to improve, with the nugget being cathodic
