Abstract
An exemplary method of making a piston assembly may include providing a piston crown defining at least in part an upper combustion bowl surface. The piston crown includes at least one crown mating surface. The method further comprising moving the crown mating surface in proximity to a skirt mating surface defined by a piston skirt, wherein the crown and skirt cooperate to define a cooling gallery extending about a periphery of the crown. The method may further include bonding the crown and skirt together by initiating an electric current along a conductive path between the crown and skirt mating surfaces, the conductive path comprising at least one conductive material extending from the crown mating surface to the skirt mating surface.
