Magnesium; joining; dieless clinching

The application of conventional mechanical joining methods for joining magnesium parts is restricted by the limited formability of magnesium at room temperature. Dieless clinching is a new clinching method that works with a flat anvil as a counter tool, thus offering important benefits for the joining of magnesium. It is possible to decrease the heating time to 1 s or less, instead of 3–6 s with conventional clinching methods. This article discusses the mechanism and limits to possible heating time reduction and introduces new findings on the impact of adhesives between parts.
