 Friction stir spot welding, FSSW, of similar AA5052H32 joints has numerous benefits in shipbuilding, aerospace, and automotive structural applications. Additionally, studying the role of tool rotation speed on the microstructure features, achieved textures, and joint performance of the friction stir spot welded, FSSW joint still needs more systematic research. Different FSSW AA5052H32 lap joints of 4 mm thickness were produced at different heat inputs using three tool rotation speeds of 1500, 1000, and 500 rpm at a constant dwell time of 2 seconds. The applied thermal heat inputs for achieving the FSSW processes were calculated. The produced joints were characterized by their appearance, macrostructures, microstructures, and mechanical properties, hardness contour maps and maximum tensile shear load at room temperature. The grain structure and texture developed for all the FSSW joints were deeply investigated using an advanced electron backscattering diffraction, EBSD, technique and compared with the base material, B.
