Abstract
Dissimilar welding of aluminum to magnesium alloy sheets is desired for automotive body structures, but challenging due to the formation of brittle intermetallics at the interface. In a previous study, friction stir welding was utilized to evaluate the joining potential of a cast magnesium alloy to aluminum alloy sheets, and specifically to produce robust and reliable friction stir welds between sheets of wrought AA6022-T4 aluminum alloy and cast AM60B magnesium alloy. The welds are generally stronger when welding is conducted from the aluminum-sheet side, given the thickness of aluminum is half that of magnesium. In the present study, friction stir welding was further developed to produce structural welds between these sheets from the aluminum side, with and without adhesive at the faying surface. The effect of adhesive on the interface was examined for resultant material mixing and microstructure. Mechanical performance of welds was also evaluated.
