  • Process for making heterogeneous joints under shielding gas
    Patent number: 7189941
    Abstract: In joining heterogeneous materials that differ in their melting points, a shielding gas mixture with active gas content is utilized. In particular, the shielding gas mixture contains helium and active gasses in the vpm range (0.005 to 0.5% by volume). These shielding gases to lead to the production of high quality joints when joining aluminum and steel.
    Type: Grant

  • Process for MSG-soldering and use of a shielding gas
    Patent number: 6624387
    Abstract: The invention relates to MSG-soldering (metal shielding gas-soldering) of metallic materials with use of soldering and an electric arc with consumable electrode or non-consumable electrode, whereby a shielding gas that essentially consists of inert gas is used. According to the invention, the shielding gas contains at least one active gas component in addition to the inert gas. As active gases, oxygen and/or carbon dioxide can be used. The proportion of active gas in the shielding gas is preferably in the range of 0.01 to 0.5% by volume.
