Beschreibung
Zusammenfassung:	The utility model discloses a concentric welding tool for a combustion chamber shell. Comprising a welding support, a transmission mechanism, a limiting mechanism and a tensioning mechanism. The transmission mechanism is arranged on the welding support, the limiting mechanism and the tensioning mechanism are arranged on the transmission mechanism in a sleeving mode, a rear shell is arranged on the limiting mechanism, the limiting mechanism limits the rear shell and the tensioning mechanism, a front shell is arranged on the tensioning mechanism in a sleeving mode, and the limiting mechanism is arranged on the front shell. The tensioning mechanism abuts against the connecting position of the front shell and the rear shell in the tensioning state, the front shell and the rear shell are tensioned, and the transmission mechanism, the limiting mechanism and the tensioning mechanism are concentric. In the loading state, the front shell and the rear shell are kept concentric in the rotating process through the limiti
