The invention provides a weldless air entraining structure, meeting the multi-stage air entraining requirement, of an axial flow air compressor of a gas turbine. The weldless air entraining structure comprises an outer casing, an inner casing, a positioner A, a positioner B, a partition plate A, a partition plate B and a guider. The inner casing is mounted in the outer casing to form an annular cavity, and air collection cavities with the same number as air entraining positions are formed through partition of a partition plate A, a partition plate B and annular bosses of a positioner A and a positioner B on the inner casing; the positioner B and the guider are installed in a U-shaped groove in the outer surface of the inner casing. According to the gas turbine axial flow compressor, a double-layer casing air entraining structure meeting the multi-stage air entraining requirement is met, modular design and assembly of the structure are facilitated, weld joints are reduced, the machining manufacturability is im
