In this work, the effect of the pin diameter on the microstructure, hardness, and strength of friction stir welded 6061-T6 aluminum alloy to dual phase steel has been investigated. Microhardness measurements, tensile shear tests, optical microscopy, scanning electron microscopy with energy dispersive spectroscope (EDS), and X-ray diffraction were the main techniques used. The results showed that friction stir welding can be used for the joining of dissimilar 6061-T6 aluminum alloy to dual phase steel. We have found that the maximum strength is obtained after welding with the highest pin diameter.
