Zusammenfassung:	PURPOSE:To prevent defects from occurring near a welded part by arranging a half coupling outside a manifold inserted into a buttering layer and a through hole on the tube wall of a base tube and welding the half coupling and the base tube in the presence of cooling fluid in the through hole. CONSTITUTION:The buttering layer 19 is formed in the through hole 12 penetrated on the tube wall of the base tube 9. The end part outside the connecting pipe 13 inserted into this hole is welded 15 to the buttering layer 19. The half coupling 14 is arranged outside the manifest 13 and this base part and the outer wall surface of the base tube 9 are welded as the cooling fluid is provided in the through hole 12. By this method, defect parts inside the tube wall can be prevented positively from occurring.
