Summary:PURPOSE:To prevent a center line of both brazed tubes from offset to prevent a center line of one of tube from inclining relative to a center line of the other tube so as to prevent the generation of brazing defect and to make setting up work simple prior to brazing. CONSTITUTION:It is the brazing method between an Al tube 1 coated with a brazing filler metal 2 on the outer circumference and a stainless steel tube 4. At the end part of the Al tube 1, a tapered engaging part 3 reducing its diameter gradually toward tip is formed. At the end part of the stainless steel tube 4, a tapered receiving part 6, to which the tapered engaging part 3 of Al tube 1 is inserted, is formed. The engaging part 3 of Al tube 1 is inserted into the receiving part 6 of stainless steel tube 4, Both tubes are vertically held as Al tube 1 is upper side, under this condition, both tubes 1, 4 are brazed.
