The invention discloses a high-yield rotary welding structure. The high-yield rotary welding structure comprises a welding subject provided with a ventilation channel, and a welding object which is rotationally welded to the welding subject and used for communicating with a ventilation opening; the surface of the welding subject is provided with a welding ring groove surrounding the ventilation channel; the welding object protrudes outwards to form a rotary sleeve used for being embedded in the welding ring groove; a fusion welding part is formed at the front end of the rotary sleeve, rubs against an annular fusion welding rib arranged at the bottom of the welding ring groove to be fused and then flows towards an inner material overflowing zone and an outer material overflowing zone on thetwo sides in the radial direction to form welding, and the cross section of the annular fusion welding rib is in an arc shape; by arranging the annular fusion welding rib at the bottom of the weldingring groove, the annular
