The invention discloses a manufacturing method and device for a composite friction stirring near-net forming additional material. The device comprises a mold base, cavity plates and a cover plate. End baffles are mounted at the two ends of the mold base. A cushion block is put in a cavity of the mold base, and the two ends of the cushion block abut against the end baffles. A lateral baffle is mounted on the side face of the cushion block. The cavity plates are arranged on the upper portion of the cushion block. Each cavity plate is arranged in a left-and-right split manner, and a rectangular clearance is reserved in the middle of each cavity plate. The cover plate is connected with the upper portion of the mold base, and a rectangular groove hole is formed in the middle of the cover plate. In the additional material manufacturing process, the cavity plates are additionally mounted, and therefore continuous and efficient operation of adding a to-be-stirred material in the composite additional material manufacturing process is achieved, and the device can achieve manufacturing of the composite near-net forming additional material in a solid state. The device is simple, easy and convenient to operate and high in material utilization rate, and the defects such as air holes generated by a fusion method are avoided.
