1. A method for allowing at least one fluid to flow over a welding area of a workpiece along a welding path during a welding process, the method comprising:
flowing the at least one fluid onto the welding area via at least one inlet and a plurality of channels having openings, wherein the openings of the channels are divided into at least two sectors, and
individually controlling at least one flow parameter of the at least one fluid of each sector,
wherein at least one flow parameter of at least one fluid of at least one sector is controlled depending on the geometry of the welding path and/or depending on the geometry of the workpiece.
