Abstract: <P>PROBLEM TO BE SOLVED: To provide a welding method by which welding of a butted part between a cylindrical body and a corrugated heat radiation plate is excellently performed without having underfill of weld metal in the butted part between the cylindrical body and the peaks of the heat radiation plate.  <P>SOLUTION: With the butted part between the cylindrical body 2A, 2B and the peaks m of the corrugated heat radiation plate 1 as an increased heat input section α, welding torches 6a, 6B are displaced in the rotating direction of an object 4 to be welded (object) when the increased heat input section is welded, thereby reducing a relative moving speed between the welding torches and the object, securing weld reinforcement of the weld metal in the increased heat input section α. With the section other than the increased heat input section as a reduced heat section β, the welding torches are displaced in the direction opposite to the rotating direction of the object in the reduced heat section, thereby increasing the relative moving speed between the welding torches and the object, preventing excessive welding heat input. Thus, the welding is excellently performed in the butted part between the peaks of the corrugated heat radiation plate and the cylindrical body.  <P>COPYRIGHT: (C)2011,JPO&INPIT
