Abstract

The invention provides a submerged-arc welding system for an external circular seam of an external liner container of a LNG (Liquefied Natural Gas) low temperature tank car. The submerged-arc welding system comprises a bearing platform, a plurality of roller carriers, an operation mechanism, a welder and a controller. In a welding process, a to-be-welded tubular workpiece is placed on the roller carriers at intervals, and then, the controller controls the operation mechanism to run and drive the welder to move along three mutual vertical directions, so as to locate the welder in place and finish the welding. Furthermore, the workpiece is driven to rotate relative to the welder by rolling the roller carriers, so that the welding of the circular seam is realized. The workpieces in different diameters can all be directly loaded on the roller carriers. In the welding process, the welding can be realized through the running of the roller carriers and the operation mechanism and no complex adjustment is required. Thus, the submerged-arc welding system for the external circular seam of the external liner container of the LNG low temperature tank car can effectively increase the welding efficiency.
