It should be noted here that not only is the production of such a welding wire supply nozzle with holes for the gas supply technically complex, but the energy and cost expenditure must be increased for this, so that not only in Ecologically but also economically gives an unsatisfactory balance of payments
In addition, the gas supply during the welding process is already exposed to very high temperatures during the supply through the heated wire supply nozzle, so that the flow of process gas due to the high temperature that can pass through the welding wire supply nozzle also causes gas in the welding area or welding site The uniformity of supply is not optimal
[0004] Furthermore, a device for guiding welding wire and process gas to a welding device according to the preamble of claim 1 is known from US 5,313,046, however, said device also does not ensure a satisfactory uniform supply of the process gas, Because the arrangement of the holes leading the process gas through there cannot avoid inhomogeneities

Embodiment Construction
[0025] exist figure 1 An exemplary embodiment of a device according to the invention for supplying welding wire and process gas to a welding device is shown in different views in to 3 . here, in figure 1 The basic elements of the device can be seen particularly well in , while in figure 2 and 3 show the structure of the individual elements.
[0026] The device for supplying welding wire and process gas to the welding device has a profile 3 configured as a profile tube, which is connected on the one hand to a base 10 with a device for connecting the device with a wire feed and process gas. Connecting elements 5 and 8 for storage container connection. On the other hand, the profile 3 configured as a profile tube has at its other end a nozzle holder 2 into which the welding wire supply nozzle 1 is inserted.
[0027] especially if figure 2 It can be seen that the base 10 is provided with a process gas channel 12 which extends, on the one hand, into the connection element 8 ...

The invention relates to an apparatus for feeding welding wire and process gas to a welding device. The apparatus comprises a wire feeding nozzle (1) which has a welding wire channel (4), a nozzle block (2) releasably connected to the wire feeding nozzle (1), a profile (3) releasably or fixedly connected to the nozzle block (2), having a welding wire channel (6) and capable of being connected to a welding wire conveying device, and a process gas feeding device provided with a process gas channel (9). The process gas feeding device can be connected to a process gas storage container. 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 gas channel (9) and are arranged parallel to or at an acute angle of + / -5 degrees to the welding wire channel (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).
Description
technical field [0001] The invention relates to a device for supplying welding wire and process gas to a welding device according to the preamble of claim 1 . Background technique [0002] Such devices for supplying welding wire and process gas to welding devices are known in various ways. Usually, the device has a welding wire supply nozzle with a welding wire channel, wherein the welding wire supply nozzle is detachably connected to the nozzle holder. The nozzle holder is in turn releasably connected to the profile, which is provided with a wire channel and connected to the wire feed. Furthermore, such a device has a process gas supply, which usually has at least one process gas channel, wherein this process gas supply is connected to the process gas storage container. Usually the process gas supply is provided here with gas nozzles which are placed on the nozzle holders so that the process gas is discharged directly through the nozzle holders. Process gas is basically ...
