The invention provides a carbon steel structural component self-compression electric arc additive manufacturing method which comprises the following steps: independent wire filling is cooperated with the self-compression electric arc additive manufacturing method to carry out layered overlaying weld forming on a revolving part, that is, a wire feeding mechanism fills wires; self-compression electric arc serves as a heat source to melt the wires so as to carry out overlaying weld forming; and the vertical movement of a welding gun and the turnover and rotating motion of a deflection machine are utilized to form an overlaying weld path, so that the overlaying weld process of the structure-variable revolving part is always vertical revolving part. The welding gun moves by a fixed height in the vertical direction when a layer is subjected to overlaying weld, the overlaying weld manner is repeated to form a next annular overlaying weld layer, and finally, the annular overlaying weld layers are accumulated and overlapped to form the carbon steel structural component with special geometrical characteristics through reciprocating circulation. The structural component is stable in overlaying weld forming process; and a formed component is high in density and mechanical property, reaches or excesses the traditional combined process component manufacturing level of the component made of the same-component material, is high in forming precision and material utilization ratio, is simplified in manufacturing process, and is high in metal deposition velocity and production efficiency.
