Definitions

  • the present invention relates to a filler material for soldering sheets with the features of claim 1.
  • Additional materials of the type mentioned above are used in particular in the automotive industry, where they are used for joining thin-walled body panels.
  • it is particularly important to keep the heat input required for joining as low as possible, on the one hand to join together sheets as distortion-free and on the other hand, the zinc coating of the sheets during the joining process as little as possible damage, and so to allow a joint seam with the least susceptible to corrosion.
  • the present invention is therefore based on the object to propose a copper-containing filler, which has a relatively low melting point.
  • According to the invention contains the filler in weight percent 15 to 40% Zn, 5 to 30% Mn, 0.01 to 10% Ni, not more than 1% of the usual impurities and Cu as the remainder.
  • the relatively high proportion of zinc it is due to the interaction with the other alloying constituents that the inventive, in particular corrosion-resistant filler material not only when welding in the metal inert gas (MSG) method or laser soldering or in particular in metal inert gas (MIG) soldering stainless steel sheets is used, but due to its relatively low melting temperature, which may be significantly below 900 0 C depending on the composition of the alloy in the specified range limits, especially for joining thin sheets is suitable, with sheet thicknesses that can be less than 1, 5 mm.
  • MSG metal inert gas
  • MIG metal inert gas
  • the suitability for the solder connection of thin sheets is due in particular to the low energy requirement due to the low melting temperature.
  • the correspondingly reducible energy input results in a lower distortion of the sheets.
  • the filler material according to the invention is also particularly suitable for joint connection of different thickness sheets, as is the case for example in the transition between the body and the chassis of a vehicle.
  • the low melting temperature makes the filler according to the invention particularly suitable for joining galvanized sheets, since at a vaporization temperature of the zinc of 91 1 0 C in comparison to the use of known filler materials, a much lower evaporation rate of the zinc coating can be achieved.
  • the alloy according to the invention comprising Zn, Mn and Ni, the filler is characterized by a good flow and wetting behavior as well as good gap bridging in order to ensure a stable and tight seam as a result.
  • the high surface tension of the molten filler material which is attributable in particular to the Mn content of the alloy in conjunction with the low melting temperature, also contributes in particular.
  • the inventive filler has very good cold-forming properties, so that a manufactured from the filler material according to the invention welding or soldering wire is inexpensive to produce with a diameter of 0.8 mm or smaller. Due to the good wetting behavior and resulting from the alloy composition greyish color of the filler material, it resembles the appearance of a sheet surface, so that the filler material is particularly suitable for use in the outer skin of a body. Thus, a composite of different sheet metal blanks outer skin receives a one-piece appearance despite the solder seams.
  • the filler contains 20 to 25 wt% Zn, 8 to 13 wt% Mn and 0.2 to 1.2% Ni.
  • this embodiment is suitable for joining stainless high-alloy sheets.
  • an alloy of the filler with 22 wt .-% Zn, 10 wt .-% Mn and 0.5 weight percent Ni especially when maintaining a respective tolerance range of +/- 10% for the specified alloying components, regardless of given each actual composition of high-alloy sheets to be joined together is particularly universally applicable.
  • the filler material 27 to 33 wt .-% Zn, 15 to 25 wt .-% Mn and 2 to 6 wt .-% Ni the filler is particularly suitable for the connection of high-strength sheets, there strength increases due to the increased Ni content. With an increase in the Mn content is one Increased toughness of the material connected, so that in particular the production of falling seams is facilitated.
  • Wt .-% Ni in each case in a tolerance range of +/- 10%, has universal use.
  • the usual impurities should not exceed 0.2
  • the filler material for joining advantageous effects, which are due in particular to the rings GE melting temperature of the filler can be further increased by the filler is used to perform a soldering or welding process with a beam source as a heat input device. Since a very discrete heat input is possible by means of a beam source, it can be ensured that the already relatively low joining temperature is limited to a narrow local area, so that the risk of distortion of the blanks during joining or a high evaporation rate applied to the sheet blanks zinc coating is further minimized.
  • the filler according to the invention is suitable for use in the arc process; both in continuous operation and in pulsed operation.
