A multiple spot vaporizing foil actuator weld (VFAW) system includes a target sheet layer secured relative to a stabilizing component, such that standoff components may be arranged sandwichably between the target and a flier sheet layer. An electrically insulating layer separates the flier from a vaporizing component sheet layer, which may comprise at least two vaporizing subsections configured to have less conductive material than at least three dividing subsections that separate the vaporizing subsections. The geometry and/or other features of the vaporizing subsections may be varied to optimize the vaporization. A second electrically insulated stabilizing component may sandwichably secure the above components between the first stabilizing component in order to control the forces generated in the VFAW process. The method involves loading the vaporizable component sheet layer with electrons via applied voltage such that the vaporizing subsections sublimate. The rapidly expanding gas particles accelerate the flier, completing the weld.
