Abstract
In a process for the production of a shielding gas mixture argon is withdrawn from a liquid argon supply, vaporized and mixed with a gas premix. The gas premix contains helium and/or argon and a doping gas. A shielding gas mixture prepared this way is outstandingly suited, especially because of the helium content, for arc welding of aluminum and aluminum alloys.
