HRP980570A2 - Welding torch with a contact socket and a feed device - Google Patents

Description

The invention relates to a torch with a contact jacket and one supply device, as described in claim 1. A wide variety of contact jacket burners are known, where forced contact of the welding wire with the contact jacket is achieved through a specially designed contact jacket. There is known, according to DE 44 10 370 A1, the forced contact of a welded wire with a contact liner, in which the contact liner shows a free space along one part of its length where a customized contact part is inserted by means of spring tension and a corresponding contact part. The contact part is pressed against the welding wire by means of the spring tension, so that the contact part is forced into contact with the welding wire. The disadvantage is that it takes a lot of work to make it, which results in high costs for making the contact liner, and when the spring tension is reduced, trouble-free contacting is not ensured.

The task of the present invention is to create a burner with a contact jacket and a supply device, where the welding wire is forcibly contacted with the contact jacket, whereby conventional contact jackets can be used on sale.

This task of the invention is solved by the characteristics in the part of the claims 1. The surprising advantage of this apparently simple solution lies in the fact that, by means of the angular supply of the welding wire to the opening of the contact jacket, a defined contact surface is created in the contact jacket, so that a forced contact, a welded joint is obtained wires with contact jacket. A further unforeseeable advantage lies in the fact that, when using welding wire of lower training and/or constant spring, forced contact of the welding wire with the contact jacket is always ensured.

Designs according to requirements 2 to 10 have the advantage that it is possible to easily adjust the most different diameters of the welding wire.

The advantage is the design according to requirements 11 to 16, because this ensures a seamless transition of the welding wire from the feeding device to the contact jacket.

Performances according to requirements 17 to 21 are also possible, because this results in a more favorable production of the burner.

In the case of variants according to requirements 22 to 25, the advantage is that a torch can be used in accordance with the state of the art, whereby at least one contact surface is again created between the welding wire and the surface of the drilling/opening/contact liner by drilling the contact liner in the corner. , so that a forced connection of the welded wire is ensured.

The versions according to claims 26 to 29 also have an advantage, because by turning the welding wire to the contact jacket, a certain contact surface is created in the opening of the contact jacket for forced contacting of the welding wire.

Finally, the design and manufacture according to requirements 30 to 34 are advantageous, because the arrangement of the slanted surface of the contact liner removes the welding wire so that when entering the opening of the contact liner, a certain contact surface is created.

The invention is explained in more detail on the basis of examples of the embodiment shown in the drawings.

This is how they show:

Figures 1 to 3 show torch 1, for example, for MIG/MAG welding, where torch 1 is made for a welding robot.

Burner 1 consists of a supply part 2 through which burner 1 is connected to the welder or source of current for welding and at the same time shows the function of bringing current to the welder or of the power source for the welder to the burner 1. An insulating ring 3 is attached to the supply part 2, so that the front part of the burner 1 is isolated from the supply part 2, which prevents current from flowing to the outer surface of the burner. The current, which is supplied via the supply part 2 to the burner 1, is supplied inside the outer casing 4 to the end part 5 of the burner 1 and is led from the end part 5 of the burner 1 to the welding wire 6.

The outer shell 4 can be composed of several individual parts 7 to 9, whereby it is preferred that the outer shell 4 is made of a steel tube. The torch 1 can be attached to one arm of the welding robot with the provided individual part 7.

As is better visible in Figure 2, the supply part 2 is connected to the torch 1 for the welder or. to the source of current for welding, the current is transferred via the supply part 2 to the supply/feeder/pipe 10. The supply pipe 10 can be made from a copper pipe.

An insulating layer 11 is now placed on the supply pipe 10, which extends from the insulating ring 3 to the end 5 of the burner 1, so that the supply pipe 10 is completely surrounded by this insulating layer 11. Of course, it is possible that instead of the insulating layer 11 pull the insulating pipe over the supply pipe 10.

In order to achieve better cooling of the burner 1, a cooling tube with longitudinal grooves can be placed, for example, on the insulating layer 11 over one part of the burner 1, which achieves better cooling of the burner 1 or of the outer casing 4. The cooling pipe 13 has a groove around its circumference 14 at the end, so that the individual grooves 12, and especially in every other groove 12, press air or water can escape from the remaining slots.

On the cooling pipe 13 or. the outer sheath 4 is now placed on the insulating layer 11, so that a solid support of the individual layers or parts of the pipe superstructure. The individual part 9 of the outer casing 4 shows an internal thread at the rear, so that the insulating part 15 with an external thread can be attached. Then a gas nozzle 16 can be placed over the insulating part 15 and one part of the individual part 9. Furthermore, on the end part 5 of the burner 1, one transition part 17 is connected to the supply pipe 10. The connection of the transition part 17 to the supply pipe 10 can be performed by soldering, gluing or by screwing. The transitional part 17 has 2 different bores (borunga) 18, 19. The bore 18 is positioned with its central axis 20, which is located in the center of the bore 18, in the same line with the longitudinal central axis 21, which is in the center of the burner 1. The bore 18 of the transitional part 17 extends over one part 22 of the transitional part 17, whereby an internal thread 23 is placed in the hole 18 completely or over one part, into which the contact sleeve 24 can be screwed. The contact sleeve again shows a hole 25 with a diameter of 26 , which is adapted to the outer circumference of the welding wire 6. One central axis 27 located in the center of the hole 25 is aligned with the longitudinal central axis 21 of the burner 1 or. of the central shaft 20 of the transition part 17.

The contact jacket 24 has the task of conducting the current, which flows from the supply part 2 through the supply pipe 10 to the transitional part 17 and from this to the contact jacket 24, to the welding wire 6, which is shown schematically, so that the transition of the current to the welding wire 6 be as close as possible to the welding point. It further shows the transition part 17, especially in the area of the bore 17, individual around the circumference of the center-directed bore 28. It is understood that the transition part 17 is composed of several individual parts, which can then be combined into a single part.

In the burner 1, there is a supply device 29, which can be made, for example, from a copper pipe 30. The copper pipe 30 is placed in such a way that a symmetrical shaft 31 in the center of the copper pipe 30 is arranged parallel to the longitudinal axis 21 of the burner 1, i.e. .that the copper tube 30 is moved from the middle of the burner 1, so that one surface 32 of the copper tube 30 contacts the inner surface 32 of the copper tube 30 with the inner surface 33 of the supply tube 10 and thereby creates a contact surface 34. In addition, a supply device 29 is provided into the bore of the transition part 17.

The copper pipe 30 of the supply device 29 is at the end part 5, i.e. in the part where the copper pipe 30 enters the transitional part 17, turned at an angle 35 in the direction of the longitudinal central axis 21, so that when the winding wire 6 is introduced into the supply device 29, it is rotated so that the welding wire 6 is rotated into the hole 25 of the contact sleeve 24.

In this case, it is possible to insert a guiding device 36, which can be formed from a spiral spring, to guide the welding wire 6 into the feeding device 29 to see the welding wire 6. This has the advantage that the welding wire 6 can be more precisely guided in the feeding device 29 , because the outer sheath 37 of the welding wire 6 has a significantly smaller diameter – the inner diameter 38 of the supply device 29 is larger. The supply device 36 has the same or larger internal diameter than the outer sheath 37 of the welding wire 6, whereby the external diameter of the supply device is equal to or smaller than the internal diameter 38 of the supply device 29. This ensures that by simply changing the supply device 36 the burner 1 can be used with different outer sheaths 37 of the winding wire 6. But that is why the contact sleeve 24 must be adjusted to the appropriate diameter or the outer sheath 37 of the welding wire 6, i.e. when using a thicker welding wire 6, the contact jacket 24 is used, where the diameter 26 of the hole 25 of the outer sheath 37 corresponds to the outer sheath of the welding wire 6 or that it is bigger.

Furthermore, one or more additional pipes 39, 40 can be arranged in the inner part of the supply pipe 10, whereby these can be attached to the surface 32 of the supply device 29 and on the inner surface 33 of the supply pipe 10. For this, for example, the additional pipe 39 can be used for the pre-flow of water and an additional pipe 40 for supplying compressed air. In this case, it is possible, for example, that the additional pipe 39 is led over one part of the burner 1, whereby when using the additional pipe 39 as a water supply pipe, it ends with the cooling pipe 13, so that through one hole between the additional pipe 39 and of the circumferential groove 14 can be arranged by the connecting pipe 41 - as shown in dashed lines. By placing the connecting pipe 41, it is possible to supply water for cooling the burner 1 inside, i.e. inside the supply pipe (supply pipe) 10 and through the connecting pipe 41, water is transferred from the additional pipe 39 to the volume groove 14 of the cooling pipe 13, so that in certain grooves 12 of the cooling pipe 13 lead to a return flow of water.

Furthermore, it is possible for the additional pipe 39 to create its own cooling circuit inside the supply pipe 10, in which case the additional pipe 39 ends in the area of the transition part 17. The additional pipe 39 must be isolated from the further supply pipe 40, i.e. to make separation wall around the further additional pipe 40, so that when the cooling liquid is discharged from the additional pipe 39, this cooling liquid cannot penetrate into the further additional pipe 40 and the supply device 29. Then the cooling liquid flows out of the additional pipe 39, i.e. in the supply pipe 10 to the end burner 1.

In the further arranged additional pipe 40, it can be used for the supply device for automatic cleaning of the gas nozzle 16, i.e. that particles of dirt produced during welding and which collect in the gas nozzle 16 can be blown out using compressed air. At the same time, the additional pipe 40 ends in the area of the transitional piece 17, so that when compressed air is blown into the additional pipe 40, it enters the bore 19 of the transitional part 17. On the circumference of the transitional piece 17, exit openings 42 are provided in the bore of the bore 19, so that the compressed air with the bore 19 goes out through the outlet openings 42 and thus flows to the gas nozzle and from there blows away the dirt in the direction of the contact liner 24.

If welding is now to be performed using the torch 1, then the welding wire 6 is automatically introduced from the torch into the guide device 36, i.e. the welding wire 6 is introduced from the winding device via the feed into the torch 1, so that the welding wire 6 along the feed device 29 is brought to the contact liner 24. Based on the layout of the supply device 29 outside the longitudinal middle axis 21 of the burner 1, it must be turned at the end 5 of the supply device 29 by an angle 35, so that the screw wire 6 at the end area 5 is turned, so that it can follow perfect entry of welding wire 6 into bore 25 contact liners 24 or. into the hole 18 of the transition part 17.

By obliquely feeding the welding wire 6 to the hole 25 of the contact liner 24, it is achieved that a permanent defined contact surface 43 is created inside the contact liner 24, because the welding wire 6 on the surface of the hole 25 of the contact liner 24 is always redirected in the direction of the central axis 27 of the hole 25. But in this case, it is possible to create a further contact surface 44 in the area of the entrance to the hole 25 based on one fracture 45 on the welding wire 6. If both contact surfaces 43, 44 are connected, a straight line 46 is obtained, which is shown by a broken line. The straight line obtained from both contact surfaces 43, 44 shows the angle 47 to the longitudinal central axis 21 and thus to the central axis 27 of the hole 25. With this angular arrangement of the welding wires 6 or thus induced bending of the welding wire 6 in the end area 5 of the supply device 29, the forced contact of the welding wire 6 with the contact jacket 24 is achieved.

The advantage is that this permanent connection of the welding wire 6 with the contact jacket 24, i.e. forced contact, ensures a perfect current flow between the contact jacket 24 and the welding wire 6, even when the welding wire 6 is used with less training or with a smaller constant, because I mow or the angled lead to the contact liner 24 always creates a defined contact surface 43 in the contact liner 24.

A further advantage of the curved supply of the welding wire 6 to the contact liner 24 lies in the fact that by creating a defined contact surface 43 in the area of the welding place or in the contact jacket 24, the resistance of the welding wire 6 remains constant and the regulation of the welding process is improved.

When welding with a torch according to invention 1, especially for the MIG/MAG welding process, a protective gas envelope 48 must be created around the welding wire, in order to prevent the access of oxygen, so that with the light arc 49, as shown schematically by the arrow, proper welding can be carried out. For this, the gas 50, and in particular the shielding gas, as shown schematically by the arrow, is fed to the transition part 17 by the supply device 29, this means that the gas 50 comes simultaneously with the welding wire 6 via the supply device 29 into the contact jacket 24. In the transition part 17 the gas 50 can exit through the holes 28 into an internal space 51 of the gas nozzle 16, so that a protective gas envelope 48 can be created around the welding wire 6 in the area of the arc 49.

The advantage of this supply of gas 50 is that at the same time gas 50 also enters the hole 25 of the contact jacket 24 and thereby creates a dense atmosphere for the welding wire 6, so that corrosion on the hole 25 is avoided and thus always achieves a very good transition of current from the contact jacket 24 to welding wires 6.

Figure 4 shows another example of the design of the torch 1 for bringing the welding wire 6 to the contact jacket 24, where the same symbols are used for the same parts. In the shown examples of the burner 1, the final part 5 is shown on an enlarged scale.

In this case, the burner 1 is created again via the feed, supply pipe 10 with the surrounding layers, as described in Figures 1 to 3. The supply device 29 is no longer brought to the hole 18 of the transition part 17, but ends at the hole 19 of the transition part 17 For this, for example, a stop plate 52 can be placed on the bore 19. The stop plate 52 shows the pipes arranged for individual pipes on the supply pipe 10, especially the supply device 29 and additional pipes 39, 40, as described in Figure 1 , has holes 53, in order to bring relevant media such as gas 50 to the transition part 17.

The arrangement of the stop plate 52 further achieves that the guiding device 36 also ends at the stop plate 52, so that the welding wire 6 from the stop plate 52 to one entrance opening 54 of the bore 18 of the transition piece 17 lies freely, i.e. it is not guided, while the supply device 29, as described in Figure 1, is arranged with its axis of symmetry 31 parallel to the longitudinal central axis 21 of the burner 1. By terminating the supply device 29 at the initial area of the transition part 17, it is no longer possible to automatically introduce the welding wire 6 into the bore 25 of the contact jacket 24, so that when putting the burner 1 into operation, the welding wire 6 must be inserted by hand into the hole 25 of the contact sleeve 24.

To do this, the contact sleeve 24 is unscrewed from the transition part 17, so that during the automatic feeding of the welding wire, it is fed for so long, until the end of the welding wire 6 reaches or. outside the transitional part 17 or out of the gas nozzle 16, after which the user placing the contact liner 24 on the welding wire 6 the contact liner 24 on the welding wire 6 the contact liner 24 on the transition part 17 can screw. By screwing the contact sleeve 24 onto the transition part 17, the welding wire is deformed in such a way that a forced contact of the welding wire 6 is achieved on the surface of the hole 25. This deformation of the welding wire 6 causes defined contact surfaces 43, 44 to be created in the contact sleeve. If both contact surfaces 43, 44 are connected, a straight line 46 is obtained, which is shown as a dotted line, whereby this again creates an angle 47 towards the longitudinal central axis of the bore 25. In addition, it should be mentioned that the contact liner 24 with its central axis 27 in the same line towards the longitudinal central axis 21 of burner 1.

By turning the welding wire, it is possible to create a permanent defined contact with the welding wire 6 and the contact jacket 24, i.e. a forced contact of the welding wire 6. The advantage is that the welding current, which reaches the contact jacket 24 via the supply pipe 10 , creates a seamless transition to the welding wire 6. A further advantage lies in the fact that by creating a defined or specified contact surfaces 43 or 44 significantly improves the welding regulation process.

In this variant of the design, the burner 1 is made in such a way that, for example, the gas 50 is not supplied via the supply device 29 to the transitional part 17, but the gas 50 is supplied via additional pipes 39, 40 to the transitional part 17. The gas then exits the stop plate. 52 over the hole 53, so that in the hole 19 of the transition part 17, the gas creates a protective sheath around the welding wire 6 and over the hole 28 or. of the outlet openings 42 of the bore 19 can reach the interior 51 of the gas nozzle 16 and thus creates a protective sheath 48 around the welding wire 6. It is understandable that it is possible, for example, to blow additional pipes 39, 40 with compressed air after welding, so that cleaning is possible gas nozzles 16 or bore 19.

Figure 5 shows another embodiment of the invention of the burner 1, where again only the final part 5 of the burner 1 is shown, and the same descriptions are used for the same parts as in the previously described pictures.

In the shown burner 1, the supply device 29, and especially the copper pipe 30, is arranged in the middle of the burner 1. In this case, the axis of symmetry 31 of the supply device 29 is placed in line with the longitudinal middle axis 21 of the burner 1. The supply device 29 extends to the hole 18 of the transition part 17, so that the welding wire 6 located in the feeding device 29 directly from the feeding device 29 can enter the hole 18 of the transition part 17.

Of course, it is possible that the supply device 29 ends at the transition part 17.

The central axis 20 of the bore 18 of the transitional part 17 is in line with the longitudinal central axis 21 of the symmetrical axis 31 of the supply device 29. If the contact liner 24 is now screwed onto the transitional part 17, then the contact liner 24 is arranged in the middle of the burner 21.

The hole 25 in the contact sleeve 24 is made in a curved manner, so that the central axis 27 of the hole 25 shows an angle 55 to the central axis 20 of the hole 18 or. towards the longitudinal central axis of burner 1.

By this distorted shaping of the hole 25, it is achieved that the welding wire 6 creates contact surfaces 43, 44 in the hole 25.

If both defined contact surfaces 43, 44 are now connected via the dotted line 46, then the line 46 shows the angle 47 towards the central axis 26 of the bore 18, or to the longitudinal central axis 21 of burner 1.

With this curvature, it is achieved that on the defined contact surfaces 43, 44 there is a constant fixed friction surface on the contact jacket 24 and thus the transition of current from the contact jacket 24 to the welding wire 6 is ensured.

Of course, it is possible that, for example, the hole 25 in the contact sleeve 24 is not placed at an angle, but that the hole 25 is placed outside the middle of the contact sleeve 24, so that the welding wire is again introduced into the hole 25 and thus the welding wire 6 after leaving the device for guide 36 is deflected so that contact surfaces 43, 44 are created in the liner.

Furthermore, it is possible for the contact sleeve 24 to be arranged from the middle of the burner 1, i.e. parallel to the longitudinal central axis 21, so that the welding wire 6 when entering the hole 24 of the contact sleeve 24 is deflected, which again creates in the contact sleeve 24 at least one of . several contact surfaces 43, 44. It is understandable that it is possible that the contact liner 24 and the supply device 29 are mutually arranged at an angle, which again creates defined contact surfaces 43, 44 by means of the welding wire 6.

In the welding process, the gas 50, as described in Figures 1 to 3, is supplied again via the supply device 29, so that the gas 50 can enter the inner part 51 of the gas nozzle 16 through the hole 28, so that around the welding wire 6 can be produced this protective gas 48.

It is understandable that it is possible, with this construction, that additional pipes 39, 40 can be placed inside the supply pipe 10, so that these can again be used for cleaning the gas nozzle 16, i.e. for cooling circulation.

Furthermore, it is possible, in order to obtain the exact position of certain, defined contact surfaces 43, 44 in the contact jacket 24, that the contact jacket 24 is provided with a shutter-flap, so that the exact position of the welding wire 6 is defined.

Figures 6 and 7 show another form of the torch 1, especially the hand torch 56 for a welder, where the earlier signs are used for the same parts, respectively. marks.

The hand torch 56 has a connecting device 57 for connecting the hand torch 56 to the torch leads. Via the connecting device 57, the hand torch 56 is supplied with current and voltage, as well as the welding wire 6 and gas 50, whereby the hand torch 56 is insulated /against the outer casing 4/ by insulating layers 58, so that the hand torch 56/ can be used without using without danger to the user.

In the example shown, it is visible that the hand torch 56 on the end part 5 shows a curvature 59, which achieves a better handling of the hand torch 56 for manual welding.

In the embodiment shown, the supply pipe 10 is located in the middle, so that the axis of symmetry 31 of the supply pipe 10 is in line with the longitudinal central axis 21 of the burner 1, especially the manual burner 56. The supply pipe 10 ends with a gap 60 before the transition part 17, so that between a cavity 61 is created between the end of the supply pipe 10 and the transition part 17. In order for the current from the supply pipe 10 to reach the transition part 17, it is on the outer surface of the supply pipe 10, as well as on the outer surface of the supply pipe 10, as well as on the outer surface of the transition part 17 switches the connecting pipe 62, so that a flawless contact is created between the supply pipe 10 and the transition part 17. The connecting pipe 62 can be welded or solder with the supply pipe 10 as well as with the transition part 17.

In the supply pipe 10, there is a supply device 29 made of a copper pipe 30, whereby in this embodiment, additional pipes 39, 40 are not needed inside the supply pipe 10. The supply device 29, and especially the copper pipe 30, ends again with the end of the supply pipe 10 , where the copper pipe 30 can for example be welded to the supply pipe 10 to prevent the copper pipe 30 from moving.

In order to now ensure a seamless transition from the copper tube 30 to the transition part 17, an intermediate part 63 is placed in the hollow space 61. This intermediate part can be welded to the copper tube 30 of the supply device 29 and the transition part 17, and especially the hole 19 of the transition part 17.

In order to achieve flawless contact of the welding wire 6 in the contact jacket that is attached to the transition part 17, the intermediate part 63 has a curve 64, so that the welding wire 6 fed via the supply device 29 is moved away from the middle of the manual torch 56. In the area of the transition part 17, the intermediate part 63 curves again in the direction of the longitudinal central axis 21 by one further bending 64.

This bending results in uninterrupted entry into the bore 19 of the transitional part 17, whereby the bore 19 of the transitional part 17 stands at an angle 65 to the central axis 20 of the bore 18, so that a seamless transition is achieved between the intermediate part 63 and the bore 19. The bore 18 of the transitional part is in array with the longitudinal central feature 21 of the hand torch 56, whereby the bore 18 can be provided with an internal thread 21, so that the contact sleeve 24 can be screwed into the bore 18.

The contact sleeve 24 has a bore 25, whereby this is directed in line with the central longitudinal axis 21 of the hand torch 56 and thus in line with the central axis 20 of the bore 18.

With the shown hand burner 56, it is possible for the guide device 36 to be arranged in the feed device 29, whereby the guide device 36 can be moved to the bore 18 of the transition part 17, as shown schematically.

If the welding wire 6 is now introduced into the guide device 36, then the welding wire 6 flows along the longitudinal central axis 21 all the way to the end of the supply pipe 10. At the transition to the intermediate part 63, the welding wire 6 moves away from the longitudinal central axis 21 and then flows in the direction of the outer casing 4, which in the area ends the supply pipes 10 or the end of the feeding device 29 creates several contact surfaces, 66. Then the welding wire in the transition area between the intermediate part 63 and the hole 19 is twisted in the direction of the longitudinal central axis 21, so that in the transition area between the intermediate part 63 and the hole 19 of the transition part 17 a contact surface is formed again 66. Then the welding wire 6 enters the hole 25 of the contact sleeve 24, so that the welding wire 6 on the surface of the hole 25 is deflected and thus the defined contact surfaces 43, 44 are created in the contact sleeve 24. This movement of the welding wire 6 achieves forced contact, whereby a seamless transition of current from the contact jacket 24 to the welding wire 6 is created. If both contact surfaces 43, 44 are connected via the line 46, which is shown by a broken line, then the line 46 shows the angle 47 to the central axis 20 of the hole 18.

The advantage of this deflection of the welding wire 6 lies in the fact that when the welding wire 6 is applied, at least one permanent contact surface 43 or 44 is created in the contact jacket 24, and thus a permanent transfer of current to the welding wire 6 is ensured.

In order to be able to carry out the welding process with the hand torch 56, the gas 50, which is again shown schematically by the arrow, is supplied via the supply device 29 to the transition part 17. The gas can then flow through the bore 28 in the interior 51 of the gas nozzle 16, so that at the end of the gas nozzle 16 can create a protective gas envelope 48 for the welding wire 6.

Furthermore, it is possible for the hollow space 61 to be used for the cooling flow, whereby for example the copper pipe 30 of the supply device 29 can wash the fins, so that an inlet and outlet for the cooling medium is created.

Figure 8 shows another example of the design of the torch 1 for feeding the welding wire 6 in the middle of the longitudinal central axis 21 of the contact sleeve 24, where the same markings are used for the same parts. In the shown examples of the burner 1, the end part 5 is shown on an enlarged scale.

In doing so, the burner 1 is formed again via the supply pipe 10 with the layers lying on the outside, as shown in figures 1-7. In the burner 1, the supply device 29 is arranged in such a way that the symmetrical axis 31 passing through the center of the supply device 29 lies parallel to the longitudinal central axis 21 of the burner 1, this means that the supply device 29 is moved from the center of the burner 1, so that, for example, the surface 32 of the copper pipe 30 in contact with the inner surface 33 of the supply pipe 10, thereby creating a contact surface 34.

In the transition area between the bore 18 and the bore 19, a surface 67 is arranged, which runs at an angle with the longitudinal central axis 21, whereby this becomes narrower from the bore 19 to the bore 18, i.e. in the direction of the contact liner 24. It is understandable that it is possible, in such an example of execution, that the transition part 17 is formed only from the hole 18 and the curved flowing surface 67, so that the hole 19 in the transition part 17 is not needed and thus the transition part 17 ends with the surface 67. Furthermore, it is possible, to form the transitional part 17 only from the hole 18, so a further part with a curved surface 67 is placed in front of the hole 18.

The supply device 29 does not now extend to the hole 18 of the transition part 17, but ends before or directly on the surface 67, i.e. that when the surface 67 is arranged between the holes 18, 19 of the transition part 17, the supply device 29 can enter the hole 19.

For this, for example, a stop plate 52 can be arranged again on the hole 19. In this case, the stop plate 52 shows the holes for individual pipes in the supply pipe 10, especially the supply device 29 and additional pipes 39, 40, as described in Figure 1 53, so that suitable media, for example gas 50, would be supplied to the transition part 17.

The hole on the stop plate 52 for the supply device 29 can be shaped in such a way that the supply device 29 can be inserted into the hole 19 through this hole. It is, however, possible that the supply device 29 ends already at the stop plate 52, because the arrangement of the curved surface 67 discovery welding wire 6 or. feeding device 36 in the direction of the hole 18 and thus achieves the automatic introduction of the welding wire 6 into the hole 25 of the contact liner 24.

If welding is now to be performed with torch 1, then welding wire 6 is automatically introduced from the torch into the guide device 36, i.e. welding wire 6 is introduced from one spare part (tank)/through the supply line into torch 1, so that the welding wire 6 the wire 6 is transported along the supply device 29 to the contact sleeve 24. Based on the arrangement of the supply device 29 to the contact sleeve 24. Based on the arrangement of the supply device 29 outside the longitudinal central axis 21 of the burner 1, there must be a curved welding wire 6 or the guiding device 36 for the corner, which is determined by the curved surface 67, so that the welding wire 6 or the guiding device 36 at the end area 5 is curved in such a way that the perfect entry of the welding wire 6 into the bore 25 of the contact sleeve 24 or into the hole 18 of the transition part 17.

By the curved supply of the welding wire 6 to the hole 25 of the contact liner 24, it is achieved that at least one permanent defined contact surface 43 is formed inside the contact liner 24, because the welding wire 6 on the surface of the hole 25 of the contact liner 24 is always deflected in the direction of the central axis 27 of the hole 25. But in this case, it is possible to create a further contact surface 44 in the area of the entrance to the bore 25, based on one curvature 45 created by the welding wire 6. If both contact surfaces 43, 44 are now joined, the direction 46 is obtained, shown by a dashed line. The line 46 that was created from both contact surfaces 43, 44 shows the angle 47 to the longitudinal central axis 21 and thus to the central axis 27 of the hole 25. With this curved arrangement of the welding wire 6 or. the resulting bending of the welding wire 6 in the end area 5 of the feeding device 29 results in the forced contact of the welding wire 6 with the contact jacket 24.

Finally, for the sake of order, it should be pointed out that in the drawings, individual components and entire groups are shown disproportionately and distorted in scale for a better understanding of the invention.

Individual characteristics of individual examples of execution with other characteristic marks of other examples of execution or each by itself can be the subject of independent inventions.

First of all, individual images 1 to 3 can be performed; 4; 5; 6; 7; 8 to represent the subject of an independent, inventive solution. The corresponding tasks and solutions can be discerned from the detailed descriptions of these images.
