<P>PROBLEM TO BE SOLVED: To provide a welded structure with a groove geometry welded by a single pass per layer with respect to a welding rotor. <P>SOLUTION: The welded structure is configured such that two structures with a 10 mm or more thickness are mounted to each other in a vertical direction, wherein an angle defined between the welding direction thereof and an upward vertical direction is 80-90 degree. In the welded structure, a surface layer of a welding groove is positioned in a vertical direction relative to a bottom. A surface side of the groove is inclined upward to define an angle of the welding groove, accordingly a difference between contact angles of upper and lower sides is controlled within a permissible range, thereby achieving the single pass per layer welding. <P>COPYRIGHT: (C)2012,JPO&INPIT |
