The invention provides a forming method and a forming device for a cabin section with a cabin body inner boss, and belongs to the technical field of metal plastic processing, the forming method comprises the following steps: preparing a cabin section base body; a plurality of cabin body inner bosses are formed on the inner cylinder wall surface of the prepared cabin body in an electric arc fuse wire additive manufacturing mode; and at the first preset forming temperature, the cabin inner bosses are extruded in the radial direction of the cabin base body from inside to outside to form the cabin with the cabin inner bosses. According to the method, the multiple cabin inner bosses are formed at the designated positions of the inner cylinder wall face of the cabin section base body in an electric arc fuse additive manufacturing mode in an additive mode, then the base material-additive interface metallurgical bonding quality is improved by applying radial hot extrusion to the cabin inner bosses, and the defects of uneven solidification structures, gaps and the like in an additive area are overcome; compared with a traditional inner boss riveting or welding process, the problem that the bearing performance is reduced due to introduction of a weak connection area and stress concentration is avoided.
