N2 - In this work, laser pressure welding of dissimilar aluminium and copper was conducted at a high welding speed of 15 m min−1. One-micron intermetallic compounds (IMCs) layer with heterogeneous dual-phases (copper and γ-Al4Cu9 phases) laminates in the joint interface were observed by transmission electron microscopy. The results showed that the combination of two joining mechanisms led to improved mechanical property, namely the mechanical interlocking due to the curved interface and the metallurgical bonding by the presence of the thin IMCs layer with heterogeneous laminates. The tensile shear force and the shear strength of the joint reached 2055 N and 111.94 MPa, respectively. The present study provides a more efficient method to join dissimilar aluminium and copper.
