Description
Lap joints were fabricated in 2024-T3 aluminium alloy sheets (thickness 1 or 0.6 mm) by refill friction stir spot welding (RFSSW) and the influence of tool sleeve depth on joint quality was investigated. Welding was performed at tool depths of 1.1-1.2 mm with varying plunge time to ensure a constant sleeve plunging rate of 0.6 mm/s. For each joint geometry studied, 10 RFSSW weldments were made, eight to assess the load bearing capacity with respect to plastic strain analysis, one for microstructural and macrostructural examination and one for visual inspection. Tensile/shear tests were carried out using a testing machine and the Aramis non-contact optical 3D deformation system.
