Problems solved by technology

The disadvantage is also that this measurement method increases gas consumption and therefore costs
In addition, only the NO concentration generated by the arc around the gas shielding area can be detected, which is why this measurement method has only very low information value
The reason for this is that the magnitude of the NO concentration depends on several welding parameters, e.g. arc length, welding current, etc., which however are not taken into account in the measurement

Abstract

The invention relates to an arrangement and a method for measuring a protective gas (8) used in an arc-welding process by analyzing the protective gas (8) escaping from a gas nozzle (27) of a torch (10), wherein at least one sensor (31) is arranged in an external measuring device (30) 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 (31) is arranged in an external measuring device (30) for protective-gas analysis, which sensor (31) is positioned at a distance (38) from the torch (10) which substantially equals the distance (38) between the torch (10) and a workpiece (16) in a welding process so that the escape and effect of the protective gas (8) of an actual welding process can be simulated, and that at least one sensor (31) is connected to an evaluation unit (32) and via the latter to a welding device (1).

Description

Technical field [0001] The invention relates to a device for measuring the shielding gas used in the arc welding process by analyzing the shielding gas escaping from the gas nozzle of the welding torch, wherein at least one sensor is arranged in an external measuring device for analyzing the shielding gas . [0002] In addition, the present invention also relates to a method for measuring the shielding gas used in the arc welding process by analyzing the shielding gas escaping from the gas nozzle of the welding torch. Background technique [0003] Several documents are known from the prior art describing the measurement of shielding gas. [0004] For example, DD251305A1 describes the measurement of the protective effect of the shielding gas on the arc of the welding process, where the measurement results can stabilize the welding process and ensure quality. Here, the disadvantage is that the performance of the shielding gas is not accurately analyzed because the conditions of the s...
