PURPOSE: A structure and a method for welding structure are provided to obtain structural stability by preventing structure from being broken or damaged by brittle cracks generating in a butt-welding part of steel sheets. CONSTITUTION: In a structure for welding structure, at least a part of a butt-welding unit(30) of steel sheets is composed of a first welding unit(32) and a second welding unit(34). The second welding unit is formed by the other welding material different with the first welding unit and prevents brittle cracks from spreading. The butt-welding unit and the first welding unit are formed by same welding material. The second welding unit is formed by one or more kinds of welding materials. |
