Abstract:
A method for the manufacture of an assembly comprising brazed metal parts, which includes the steps of:(a) juxtaposing parts to define one or more joints therebetween; (b) supplying to the one or more joints a nickel/chromium brazing filler metal; (c) heating the juxtaposed parts and the brazing filler metal under appropriate conditions in order to cause the melting of the brazing filler metal; (d) cooling the melted brazing filler metal to produce a brazed joint; and (e) subsequently, conditioning the brazed parts by exposing it to an elevated temperature, in an oxygen-containing atmosphere, for a sufficient time to substantially reduce the amount of nickel leaching into water or other fluids contacting the brazed joints of the brazed assembly.
