METHOD AND DEVICE FOR MONITORING INERT GAS DURING A WELDING PROCESS

The invention relates to a method and a device (30) for monitoring the inert gas (5) during a welding process performed using a welding torch (7), wherein at least one measurement variable (Pi), which is dependent on the type of inert gas (5), is measured by means of at least one sensor (Si).

Beschreibung
Zusammenfassung:	The invention relates to a method and a device (30) for monitoring the inert gas (5) during a welding process performed using a welding torch (7), wherein at least one measurement variable (Pi), which is dependent on the type of inert gas (5), is measured by means of at least one sensor (Si). According to the invention, at least two measurement variables (Pi) of the inert gas (5) are measured and the measured values (Mi) of the at least two measurement variables (Pi) of the inert gas (5) are compared with several stored values (Mi′), which are associated with inert gas types (Gi), of the at least two measurement variables (Pi), and the inert gas type (Gi), for which the assigned values (Mi′) of the at least two measurement variables (Pi) are closest to the measured values (Mi) of the at least two measurement variables (Pi)of the inert gas (5), is displayed.
