Method and device for continuously on the basis of brazing filler metal wire subjected to a complementary heating

摘要

1. A brazing process in which all the parts 8, 9 to be assembled are preheated by induction, and arranged in an electric circuit, the filler metal being brought in the presence of a flux on contact with the parts, the form of coils 1 of wire 4 reeled off continuously, process characterized in that the brazing joint 7 is subjected to heating that is complementary to and independent of the heating obtained through thermal contact with the preheated parts, by causing to circulate a strong intensity electric current in the wire 4, inserted into the above-mentioned circuit and which is in contact with parts 8, 9, this current dissipating through the Joule effect a calorific power localized and dissipated in the high value electric resistance created on the wire-part contact 7.
