Zusammenfassung:	PROBLEM TO BE SOLVED: To make a welding process and a particularly necessary maintenance procedure more efficient.SOLUTION: In a method for controlling a process for a gas nozzle 2, a maintenance procedure of a welding process is started at fixed times or depending on process parameters detected by sensors, during which procedure a welding torch 6 is positioned at a maintenance position, and a connection between the gas nozzle 2 and an internal insert 28 of the welding torch 6 is disconnected by spatial reduction in size of a fixing element 30 of the welding torch 6, and the gas nozzle 2 is removed from the welding torch 6. Subsequently, another gas nozzle 2 is positioned on the welding torch 6, and a particularly gas-tight connection is provided between the gas nozzle 2 and the internal insert 28 of the welding torch 6 by spatial expansion of the fixing element 30.
