Abstract

PURPOSE: To obtain a heat exchanger, in which stress corrosion cracking does not occur at the jointing part of the tube plate with the heat transfer pipe by a method wherein a recess formed at the part to be jointed is padded by welding and clad with a sheet plate and a tube hole is bored piercing the padded part and the clad sheet plate and a heat pipe inserted in the tube hole is welded and fixed to the padded part.
CONSTITUTION: The recess 10 is formed in the mild steel tube plate 6 and padded by welding with cupro-nickel or Monel metal. After that, the padded part by welding 11 is finished in a smooth flat plane and clad with a aluminum bronze plate 7. A hole is bored piercing the aluminum bronze plate 7, the padded part by welding 11 and the tube plate 6 and the heat transfer pipe 5 is inserted in the hole. Then, the end of the heat transfer pipe 5 is seal-welded with aluminum bronze type welding material 10 provide a seal-welded part 8.
