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.
