Abstract

PURPOSE: To prevent formation of a ring-shaped depression on the outer periphery of the weld zone when butting a tube plate and a small diameter tube and welding with a rotating electrode from inside by covering the end of the small diameter tube providing a cylindrical guide on the outer periphery face of a cylindrical projection made on the tube plate.
CONSTITUTION: In welding a tube plate 1 and a small diameter tube 2, a cylindrical projection 1b provided on the tube plate 1 is butted with the small diameter tube 2, and the butted part 5 is welded with a rotating electrode 4 of a welding machine 3 from inside. In this case, an annular cylindrical guide 7 is provided on the outside of the tip of the cylindrical projection 1b and the tip of small diameter tube 2 is fitted to its inside. In this way, the concave bead is filled with molten metal of the cylindrical guide 7. Thus, generation of depression on the outside of the weld bead can be prevented.
