Abstract
A method is provided to braze aluminum materials to each other, the method comprising a step of producing a fluoride gas-containing atmosphere within a brazing oven. The method further comprises a step of brazing the aluminum materials, by heating said materials within said atmosphere melts. The fluoride gas-containing atmosphere is produced in the soldering oven: by introducing an inert gas and the fluoride gas through different passages; by introducing into the oven a mixture of the inert gas and the fluoride gas; or by heating a fluoride in a receptacle which is placed in the oven so as to gasify the fluoride within the oven.
