DEVICE AND METHOD FOR SHIELDING GAS MEASUREMENT

摘要

The invention relates to a device and a method for measuring shielding gas (8) used in an arc welding process by analyzing the shielding gas (8) emerging from a gas nozzle (27) of a torch (10), wherein at least one sensor (31) is arranged in an external measuring device (30) for the shielding gas analysis. For rapid, exact and practical determination and correspondingly effective evaluation of the shielding effect of the shielding gas, for the shielding gas analysis at least one sensor (31) is arranged in an external measuring device (30) and positioned at a distance (38) from the torch (10) that is essentially the same as the distance (38) between the torch (10) and a workpiece (16) in a welding process, and so the emergence and effect of the shielding gas (8) of an actual welding process can be simulated and at least one sensor (31) is connected to an evaluation unit (32) and via the latter to a welding device (1).
