Abstract
The invention relates to an arrangement and a method for measuring a protective gas () used in an arc-welding process by analyzing the protective gas () escaping from a gas nozzle () of a torch (), wherein at least one sensor () is arranged in an external measuring device () for protective-gas analysis. For rapid, exact and practical determination and correspondingly effective evaluation of the protective effect of the protective gas, at least one sensor () is arranged in an external measuring device () for protective-gas analysis, which sensor () is positioned at a distance () from the torch () which substantially equals the distance () between the torch () and a workpiece () in a welding process so that the escape and effect of the protective gas () of an actual welding process can be simulated, and that at least one sensor () is connected to an evaluation unit () and via the latter to a welding device ().
