摘要： PROBLEM TO BE SOLVED: To provide a welding method by which a nozzle stub can be mounted on an inclined surface of a reactor vessel with smaller division number, so that the number of start-and-end portions for welding becomes as small as possible.SOLUTION: A container includes a surface 6 inclined to a horizontal direction. In the welding method, a welding part of a through-hole provided on the surface 6 and penetrating vertically and a welding part of a tubular member 3 inserted into the through-hole are welded. A welding torch 2 includes an electrode 4 whose tip end is inclined in one direction and whose top part 5 in the tip end lies in the periphery of the electrode, wherein the welding torch 2 is arranged vertically so that a bus bar including the top part 5 faces the surface. Thus a welding bead is formed from an upper side of the inclination toward a lower side thereof along a periphery of the tubular member 3 while keeping the bus bar facing the surface 6.
