Abstract
The invention provides a submerged-arc welding system for an internal circumferential joint of an outer container of an LNG low-temperature tanker. The submerged-arc welding system comprises a holding platform, a plurality of roller racks, an operation mechanism, a welder and a controller. When welding is implemented, to-be-welded tubular workpieces are placed on the plurality of roller racks which are arranged at intervals; subsequently, the operation mechanism is controlled by the controller to operate, and the welder is driven to move in two directions perpendicular to each other, so that welding of the circumferential joint can be achieved. Workpieces of different diameters can be directly held on the roller racks; moreover, welding can be achieved through operation of the roller racks and the operation mechanism in the welding process, and no complex adjustment is needed. Therefore, by adopting the submerged-arc welding system for the internal circumferential joint of the outer container of the LNG low-temperature tanker, the welding efficiency can be effectively improved.
