Oxygen measurement
For the evaluation of shielding gas coverage, it is crucial to know about how the ambient air contaminates the shielding gas.
The controlled extraction of a small amount of gas in the immediate vicinity of the arc and the use of the lambda sensor principle facilitate the measurement of the oxygen content of the area immediately surrounding the workpiece. The quality of the shielding gas coverage can thus be assessed and used to validate the simulation models.
