The invention relates to an apparatus for feeding welding wire and process gas to a welding device comprising a wire feeding nozzle (1), which has a welding wire channel (4), a nozzle block (2), which is releasably connected to the wire feeding nozzle (1), a profile (3), which is releasably or fixedly connected to the nozzle block (2), has a welding wire channel (6) and can be connected to a welding wire conveying device, wherein the process gas channel (9) of the process gas feeding device is arranged at least partially within the profile (3) and the nozzle block (2) is provided with multiple bores (7), which adjoin the process has channel (9) and are arranged parallel to or at an acute angel of ±5° to the welding wire chancel (4) of the wire feeding nozzle (1) and around the wire feeding nozzle (1). In this case, the nozzle block (2) is formed cylindrically in the direction of an end (14) having the wire feeding nozzle (1), wherein the bores (7) arranged within the nozzle block run out into depressions (15) on the surface of the nozzle block (2).
Apparatus for feeding welding wire and process gas to a welding device with a wire feeding nozzle (1) having a welding wire channel (4), a nozzle block (2) attached to the wire feeding nozzle (1) that is detachable, a tube (3) detachable from the nozzle block (2) or attached permanently to it and a welding wire channel (6), which can be connected to a welding wire movement apparatus, and a process gas feeding device that has a process gas channel (9), to which a process gas reservoir can be connected, whereby the process gas channel (9) of the process gas feeding device is arranged at least partially within the tube (3), and the nozzle block (2) is provided with several boreholes (7) connected to the process gas channel (9), which are arranged parallel or at an acute angle of +/−5° to the welding wire channel (4) of the wire feeding nozzle (1) and around the wire feeding nozzle (1), so characterized in that the nozzle block (2) is formed cylindrically in the direction of an end (14) having the wire feeding nozzle (1), whereby the boreholes (7) within the nozzle block discharge in recesses (15) on the surface of the nozzle block (2), whereby the recesses (15) on the surface of the cylindrical end (14) of the nozzle block (2) run from the openings of the boreholes (7) in the nozzle block (2) over the entire length of the cylindrical end (14).
