Method and carrier gas nozzle for supplying a fluid to a welding area of a workpiece

A carrier gas nozzle for allowing at least one fluid to flow over a welding area of a workpiece along a welding path during a welding process, the carrier gas nozzle (1) comprising:

• a housing,
• at least one inlet for the at least one fluid and
• a plurality of channels having openings through which the at least one fluid flows onto the welding area,
• wherein the channels with the openings are divided into at least two sectors, with at least one inlet for at least one fluid, which sectors are designed for the individual control of at least one flow parameter of the at least one fluid of each sector,
• wherein the at least two sectors are arranged depending on the geometry of the welding path and/or the geometry of the workpiece,
• wherein in each sector its own valves or its own flow controllers for the at least one fluid are provided, and
• wherein a control is provided with which the control of the at least one flow parameter of the at least one fluid of each sector can be carried out by the sector-by-sector control by means of the valves or the flow controllers, so that at least one flow parameter of at least one fluid of at least one sector can be controlled depending on the geometry of the welding path and/or depending on the geometry of the workpiece.
