Abstract

The aim of this investigation was to explore the effect of geometric tool parameters and tool probe offset on the properties of friction stir welded of 2 mm thick plates of Ti6Al4V to AA5052-H32 joints. In a probe offset distance of 0.5 mm, sound dissimilar joint with tensile strength higher than 94 % of the parent AA5052 alloy strength is produced. Increasing the probe offset distance result in more homogenous and higher quantity of titanium alloy particles in the weld nugget. Increasing welding heat input results in change of fracture zone from TMAZ of AA5052 side to weld interface. It was found that the tool with square frustum pin produces joints without defect and high strength compared to the cylindrical pin.
