Macro- and Micro-Galvanic Corrosion Mechanisms in Symmetric and Asymmetric Double-Sided Friction Stir-Welded 7A65 Aluminum Alloy Joints

The corrosion behavior of symmetric (S-joint) and asymmetric (A-joint) double-sided friction stir-welded (DS-FSW) 7A65 aluminum alloy thick plates was investigated in 3.5 wt% NaCl solution. The S-joint, produced using the same large tool (Φ30 mm) for both passes, imposes two high...
