Abstract

PURPOSE: To perform the execution which does not produce any undercut to become the cause of leakage trouble by beforehand build-up-welding the position corresponding to the final layer of the joint weld zone of the lowermost stage bottom plate and shaping the same then assembling the side plates and make regular welding.
CONSTITUTION: Beforehand, build-up welding 3 is applied to the place of cylindrical storage tank to become the toe of welding on its annular plate (bottom plate) 1 side and said part is polished to beforehand shape the same smooth. Thence, it is assembled with the lowermost stage side plate 2 and regular welding 5 is applied. Since the build-up welding in such a method is done in a blank state, the welding posture and welding place may be selected as desired. In addition, such method eliminates the welding defects such as undercuts that become the cause for brittle fracture and improves the quality of welding and the safety of work.
