The invention discloses a high-speed train, a train body and a machining method of the train body. The train body comprises a side wall, a roof and a fresh air port installation seat. One of the side wall and the roof is provided with a fresh air port for installation of the fresh air port installation seat. The fresh air port installation seat is provided with an insertion opening matched with the other of the side wall and the roof, and a joint crack formed by inserting the other of the side wall and the roof into the insertion opening and a joint crack formed by the side wall and the roof are collinear. The joint crack formed by the fresh air port installation seat and the roof and a long and straight longitudinal joint crack formed by the side wall and the roof are collinear, when the side wall and the roof are welded, the fresh air port installation seat and the roof are welded together, the welding joint continuity of the side wall and the roof can be guaranteed, the use strength of the train body is improved, and the welding process procedures can be simplified.
