Tinplate can body automatic welding equipment

The invention relates to the technical field of welding, and particularly discloses tin can body automatic welding equipment which comprises a welding machine assembly, a cutting assembly, a clamping assembly and a fixing structure, the cutting assembly and the clamping assembly are arranged on the fixing structure, the cutting assembly is fixedly connected with the welding machine assembly, and the clamping assembly is fixedly connected with the fixing structure. The welding machine assembly is fixedly connected with the fixing structure. According to the cutting device, the can body is fixed through the clamping assembly, the contact position of the can body is cut through the cutting assembly, friction is conducted through friction lines on the side face of the tool while cutting is conducted, V-shaped cutting is achieved, metal oxide on the metal surface of the contact position is effectively cut off, and the cutting efficiency is improved. And the situation that the tank is cracked due to the fact that t
