Abstract

Dissimilar metal joining of magnesium to aluminum was investigated using the latest generation nanosecond pulsed fiber laser. The tensile shear test shows that the average tensile shear strength of a joint was 86 MPa, which was 75% of the aluminum substrate. The weld interface exhibited a mixture phase (Mg solid solution and Mg17Al12) that improves the strength and toughness of the joint. A thin Mg–Al intermetallic compound layer was formed on both sides of the weld seam toward the Al side. Fracture occurred toward the Al substrate side rather than the Mg–Al interface, indicating a high joining strength at the weld interface.
