Vehicle weight reduction, by creating multi-material structures consisting of high strength-to-weight ratio materials, is one the strategies of the automotive industry to meet its fuel economy targets. Multi-material assembly raises issues of joining and corrosion and, currently, the standard solution in the industry is using fasteners and adhesives. Vaporizing foil actuator welding (VFAW) is a solid state welding technique, which enables joining of dissimilar materials without a third body. It utilizes a large pulsed current to turn a thin conductor into a highly kinetic gas, which launches one sheet of metal into another and creates an impact weld. Aluminum alloys type 5052 and 6111-T4 were welded to DP 980 and Usibor 1500 steels. During mechanical testing, failure occurred in parent aluminum. Results of mechanical testing, corrosion and advanced characterization will be discussed in light of the structure-property relationships. The stages of technology development for commercial implementation will also be presented.
