Abstract

PURPOSE: To prevent the crevice corrosion and also, to make the weld penetration against all metals uniform, by inserting the tube in the drum side fringe of pipe hole on the tube plate and forming the annular weld joint part having a step for deposition and carrying out welding butting the above step and tip end of the tube.
CONSTITUTION: The concave part 19 is formed processing concave-shaped groove by hand-reeling on the outer circumference, so as the step part 14 inserting the tube 13 in the drum 12 side fringe of the tube hole 11 and the annular weld joint part 10A having the same thikncess to the tube 13 on the outside to be left behind. Next, the insert ring 18 is attached between the tube 13 and the part 14 and the tube 13 is inserted. Hereby, weld penetration is made uniform for all materials and also, crevice corrosion is prevented and moreover, groove processing is made easy, by inserting TIG welding torch 16 in the hole 11 from the water room 15 side and welding the part 14 and the tip end part 13.
