Abstract

PURPOSE:To reduce process by putting in a stand under the welded bottom plate in moving a traveling device after completion of welding of a joint, and make it support the bottom plate until completion of the tank. CONSTITUTION:A traveling device 21 is moved to sqare the weld line of a weld groove 26 made by bottom plates 22 and 22' and the center of the backing material, and fixed. Next, the groove 26 is adjusted and a backing material sticking device and an air jack 25 are operated to stick the backing material 24 fast to the back of the groove 26. One side welding is then performed from the upper face of the groove 26. On completion of welding, the traveling device 21 is moved to a position where the center of the backing material 24 coincides with the center line of a weld groove 26'. At the same time, a supporting stand 31 is provided in the lower face of the bottom plates 22 and 22'.
