Paper Abstract

One of the challenges in the automotive industry is to reduce the carbon emission of manufactured vehicles. This can be done by incorporating light-weight metallic alloys, such as aluminum alloys and magnesium alloys, with more generic automotive modulus often made of high strength steel in order to reduce the total mass of a vehicle. To improve the load bearing capacity of dissimilar joints, optimization of the intermetallic layer thickness and the suppression of interfacial defects are key elements. In this study, a brief review is performed on the recent research progresses on laser joining of aluminum alloy to steel, in terms of different welding technologies including laser keyhole welding and laser welding brazing. Some suggestions were also put forward in the conclusions.
