Abstract

PURPOSE: To prevent the crack of weld zone and corrosion, by forming annualr weld joint part on the drum side circumference of tube hole on the tube plate and carrying out butt welding of the above joint part and tube.
CONSTITUTION: The concave part 14 is formed processing concave-shaped groove by hand-reeling on the outer circumferece, so as the annular weld joint part 10A having the same thikness to the tube 13, on the drum 12 side of the tube hole 11 circumference on the tube plate 10 to be left behind. Next, the insert ring 18 is attached between the tube 13 and the part 10A. Hereby, crevice corrosion and weld crack are prevented and welding of all materials in made possible, by inserting welding torch in the hole 11 from the water room side and welding butted part.
