<p><P>PROBLEM TO BE SOLVED: To provide a welding method in a narrow space, which can easily enhance weld strength even if a portion to be welded is located in the narrow space surrounded by structural members and the like. <P>SOLUTION: A second structural member 2 is butted against a first structural member 1 and the interface between these structural members is joined by a main welding process. When at least a part of the portion to be welded by the main welding process is located in the narrow space surrounded by the structural members or a third structural member, at least a part of the portion to be welded which is exposed in the narrow space is finish-welded by laser beam welding. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
