Design of Experiments for Friction Stir Stitch Welding of Aluminum Alloy 6022-T4 - Friction Stir Welding of Aluminum for Automotive Applications (3) - 2006-01-0970
A design of experiments (DOE) on the effects of weld parameters on friction stir stitch welding has been carried out. Lap shear specimens of automotive aluminum alloy A6022-T4 were welded using a C-frame welder. Welds were made with numerous weld parameters such as; tool pin length, tool rotating speed, tool plunging speed and depth, hold time, welding speed and weld length. The results of this study show that transverse welds have higher lap shear strength than longitudinal welds and lap shear strength increases linearly with weld length. Increasing hold time-1 and hold time-2 also increased shear strength. The effects of pin length and rpm need more investigation and will be studied further.
