1. An additive manufacturing system, comprising:
an energy source device for providing a first energy beam and a second energy beam; and
a forging device spaced from the energy source device, the forging device comprising a fixing portion and a forging head, the forging head connecting to the fixing portion and defining an inner passage extending vertically therethrough;
wherein the first energy beam and a substrate are configured to move relative to each other to fuse at least a portion of a material added to a surface of the substrate for forming a cladding layer on the substrate;
wherein the forging head is configured to forge the cladding layer during formation of the cladding layer; and
wherein the second energy beam is configured to pass from outside the fixing portion vertically through the inner passage of the fixing portion, and to heat a solid forging area of the cladding layer.
