Zusammenfassung:The invention concerns a method for brazing a heat exchanger folded tube (10), including the following operations: contacting a first tube part (20) against a support surface of a second tube part (22) at a contact zone, and brazing the first and second tube parts at said contact zone, using an input of brazing and a brazing flux (32), to form a brazed link. Such a brazing method is particularly suitable for making heat exchanger tubes having a generally B-shaped cross-section and delimiting two parallel channels (30) of fluid flow. However, said brazing method can also be used for making other types of tube from one or several metal bands.
