Abstract

Procedure for the welding of pieces of aluminum or alloys of this metal, particularly of the parts of a heat exchanger, characterized in that the pieces to be welded m are assembled without play, because these pieces are covered, at least in their parts that must be welded, with a vitrifiable enamel at a temperature lower than the melting temperature of the aluminum, because these pieces are preheated in a homo until a first threshold of temperature for which the enamel is brought to fusion, because the temperature is then raised of said parts up to a second temperature threshold corresponding to the melting and soldering temperature suitable for the welding of aluminum, said pieces are kept in this second temperature threshold for a duration comprised between two and ten icons and because said pieces are cooled.
