Definitions

  • the invention relates to a protective gas mixture for MIG / MAG brazing with argon as the main gas component and a method for MIG / MAG brazing with the protective gas mixture.
  • Shielding gases for MAG welding with solid steel wire and shielding gases with active gas components> 4.0% by volume (0 2 or CO 2 ) are currently used to connect galvanized sheets.
  • MIG soldering under pure inert gas (argon / helium) is also used.
  • high copper-containing solder wire electrodes are used, which in many cases cause a poorer melt flow when using pure inert gas.
  • the invention has for its object to provide a method for brazing galvanized materials, wherein zinc evaporation and
  • Spatter formation is reduced and droplet detachment is improved with good flank dimensioning.
  • the protective gas mixture with argon as the main component preferably contains oxygen. If oxygen alone is contained in the protective gas mixture as an oxygen-containing gas, the addition is advantageously from 0.2 to 0.6% by volume of O 2 , preferably from 0.4 to 0.6% by volume of O 2 , in particular around 0 5 vol.% O 2 .
  • Galvanized materials are, for example, galvanized steel sheets or steel profiles, preferably steel sheets with a thickness in the range from 0.5 to 1 mm, in some cases also up to 5 mm, particularly preferably 0.7 to 0.8 mm, in particular 0.75 mm.
  • the materials are usually galvanized, sensimir, hot, buna or granocoat galvanized.
  • the galvanizing generally has a layer thickness in the range from 10 to 50 ⁇ m.
  • the process for MIG / MAG brazing works with a melting and continuously supplied wire electrode, preferably with a high copper wire electrode with small proportions of Al, Si or Sn, particularly preferably made of CuSi3.
  • the wire electrode generally has a diameter in the range from 0.8 to 1.6 mm.
  • Wire diameter worked is preferably carried out in the low current range, generally in the range from 50-180 A (amperes), particularly advantageously in the range from 60-120 A.
  • the wire feed speed is preferably in the range from 3.5 to 8 m / min preferably in the range from 4.5 to 7 m / min., in particular in
  • the process is used, for example, in the manufacturing areas of the automotive industry, air conditioning technology and the construction industry.
  • Spatter formation and zinc evaporation are special application criteria, which can be significantly reduced.
  • the shielding gas mixture provides optimal results under the following process conditions: Workpiece: 0.5 to 5.0 mm solder wire: 1, 0 0 wire feed: 5.0 to 6.5 m / min.

Abstract

L'invention concerne un mélange gazeux protecteur pour le brasage fort MIG/MAG, dont le composant gazeux principal est l'argon et qui contient 0,2 à 1,2 % en volume de O2. Ce mélange gazeux protecteur est utilisé dans un procédé de brasage fort MIG/MAG de matières zinguées, procédé qui est mis en oeuvre avec des courants de faible intensité, de préférence avec une vitesse de brasage de 0,3 à 1 m/min, avec des arcs courts ou pulsés et avec une fusion du fil-électrode de 3,5 à 8 m/min.
