  • the mass MF of the sections 7 , 8 is calculated by addition of the respective individual masses of the first section 7 and the second section 8 . These in turn result from respective metal foil thicknesses DF and a length LA of the section which is contacted with brazing medium.
  • the length of the actual abutting together of the two metal foils 2 , 3 is also brought into the calculation. This approximately constant ratio is also obtained approximately when the first metal foil 2 has a metal foil thickness DF different from that of the second metal foil 3 .
  • brazing medium ML for the metal foil thickness DF described lies within these values, naturally with a corresponding upper and lower variation of approximately 10%, depending on the material composition and on the brazing method, the cell burning and cell deformation otherwise occurring with standard application of brazing medium is prevented.
  • FIG. 3 shows a further metal foil connection 9 .
  • a standard brazing medium particle fraction 10 according to the prior art is applied in the wedge 5 .
  • the wedge 5 is completely closed at its edge 11 because of the use of this standard brazing medium particle fraction 10 .

  • the brazing medium 6 is applied to these two metal foils 2 , 3 in the form of a first layer 13 on the first metal foil 2 and a second layer 14 on the second metal foil 3 . This is performed by using a modified brazing medium particle fraction which is different from the standard brazing medium particle fraction described above in the general description.
  • FIG. 5 shows a relationship between the selection of a suitable brazing medium particle fraction, shown on the Y axis, and the selected metal foil thickness DF, shown on the X axis.
  • a brazing medium particle fraction is used having a smallest brazing medium particle diameter which is larger than 25 micrometers, and a largest brazing medium particle diameter which is less than 106 micrometers.
  • the brazing medium particle fraction is adjusted in such a way that the largest maximum brazing medium particle diameter is continuously reduced, and by contrast the smallest possible brazing medium particle diameter is continuously increased.
  • brazing medium particle fractions are combined according to a linear equation along the maximum value of the brazing medium particle diameter of the individual brazing medium particle fraction. This rule for adjustment of the brazing medium particle fraction is described below with reference to the following drawings.
  • FIG. 6 shows a rule for adjustment, in order to be able to manufacture durable metal foil connections with metal foil thicknesses of less than 50 micrometers.
  • the connections are to be metal foil connections of honeycomb bodies for exhaust gas catalytic converters which are subjected to both thermal and mechanical stresses.
  • the mass of the brazing medium ML per metal foil connection is given in grams on the Y axis. This means the mass which should be found in a wedge.
  • the metal foil thickness DF is entered on the X axis. An upper limit O and a lower limit U of the mass ML are shown in the diagram.
  • FIG. 7 shows a bandwidth of the particle sizes, entered on the Y axis in micrometers, in dependence upon the selected metal foil thickness DF, entered on the X axis.
  • This diagram shows in an exemplary manner a bandwidth which has been found for the application of brazing medium to a honeycomb body.
  • a first curve 15 with solid triangles shows the limit of the minimum particle size to be selected.
  • a second curve 16 shows a maximum particle size to be selected, depending on the metal foil thickness DF.
  • Particularly good metal foil connections have been selected for honeycomb bodies when the smallest particle diameter of the brazing medium particle fraction proceeds along a third curve 17 and the largest particle diameter of the brazing medium particle fraction proceeds along a fourth curve 18 .
  • FIG. 8 shows the relationship of FIG. 6, wherein in this case, the mass of the brazing medium ML depending on the metal foil thickness DF is represented as a quotient with respect to the metal foil thickness DF. It is evident that the quotient remains approximately constant up to a metal foil thickness DF of 30 micrometers, while at 30 micrometers and less, the quotient ML/DF increases ever further.
  • FIG. 9 shows a diagrammatic representation of the Gaussian distribution of the brazing medium particle diameter, in dependence upon the metal foil thickness DF.
  • the brazing medium particle diameter is entered up to the maximum brazing medium particle diameter on the Y axis.
  • the percentage distribution is shown on the X axis. It is evident that on one hand, the maximum of the brazing medium particle diameter is approximately central in the bandwidth of the brazing medium particle fraction. It is furthermore evident that the bell-shape does not change in principle as the metal foil thickness DF becomes less, to as small a degree as does the percentage distribution of the brazing medium particle fraction per se.
  • FIG. 10 again shows the dependence of the amount of brazing medium used upon the metal foil thickness, as already shown in FIG. 6.
  • the distortion of the X axis is removed, since the distribution is regular.
  • the linearity of the lower limit U, upper limit C and ideal development I up to approximately 20 micrometers, and then the bending somewhat, is evident from these measured values.
