The invention discloses a compressor shell production line. The compressor shell production line comprises a control system, a barrel conveying and correcting device and a sleeve welding machine used for welding a barrel and a sleeve, and the barrel conveying and correcting device and the sleeve welding machine are controlled by the control system. A barrel transferring mechanism is arranged in rear of the sleeve welding machine. A barrel lid charge and press-in mechanism is arranged in rear of the barrel transferring mechanism. A barrel and lid body arc welding device is arranged in rear of the barrel lid charge and press-in mechanism. A pre-footing-welding barrel conveying and correcting mechanism is arranged in rear of the barrel and lid body arc welding device. A footing welding machine is arranged behind the pre-footing-welding barrel conveying and correcting mechanism. A support welding machine used for welding a support to the barrel is arranged in rear of the footing welding machine. A support welding and transferring mechanism is arranged in rear of the support welding machine. According to the compressor shell production line, production of compressor shells is achieved in a full-automatic mode, and the whole process is automatic, so that the efficiency and positioning precision are greatly improved, and the production cost is reduced.
