[0002] During shipbuilding, to ensure weld quality and prevent incomplete fusion of the base metal welds, arc-extinguishing plates are typically used to assist in welding. Currently, during welding operations, arc-extinguishing plates are often temporarily fixed to the base metal by spot welding, which damages the base metal. In addition, arc-extinguishing plates require on-site material sourcing and cutting, which is time-consuming and labor-intensive. Summary of the Invention

[0004] In accordance with the above objectives, a first aspect of the present invention provides an arc extinguishing device, wherein the arc extinguishing device comprises:

[0005] A fixing component is provided with a first fixing part and a second fixing part, the first fixing part and the second fixing part being detachably connected to allow adjustment of the included angle between the first fixing part and the second fixing part; and

[0006] A positioning component, which is detachably connected to the fixing component;

[0011] Preferably, the first fixing clip is located at the second end of the first base plate extending in the direction of extension; the second fixing clip is located at the second end of the second base plate extending in the direction of extension.

[0012] Preferably, both the first clamping clamp and the second clamping clamp have a first clamping portion and a second clamping portion, the first clamping portion being connected to the first base plate and the second base plate respectively, and the second clamping portion being connected to the base material respectively.

[0013] Preferably, both the first clamping portion and the second clamping portion are formed as U-shaped open structures, so that the first fixing clip and the second fixing clip are formed as an "I"-shaped structure.

[0014] Preferably, the positioning component includes a first arc-extinguishing plate and a second arc-extinguishing plate, both of which are formed as wedge-shaped plate structures, and the first and second arc-extinguishing plates are detachably connected to the first base plate and the second base plate, respectively.

However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0029] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0030] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0031] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0032] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0033] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation.

[0036] The features of the examples described herein can be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0037] According to a first aspect of the present invention, an arc extinguishing device is provided, such as... Figures 1 to 6 As shown, the arc ignition and extinguishing device in this embodiment includes a fixing component and a positioning component detachably connected to the fixing component. The fixing component and the positioning component enable the base material 40 to be detachably connected to a preset position to facilitate welding of the base material 40. The specific structure of the various parts of the arc ignition and extinguishing device according to the present invention will be described in detail below.

[0038] In this embodiment, as Figure 1 As shown, the fixing component is provided with a first fixing part and a second fixing part for fixing the base material 40, and the first fixing part and the second fixing part are detachably connected so that the included angle between the first fixing part and the second fixing part can be flexibly adjusted, thereby adjusting the welding angle of the base material 40 to adapt to different welding scenarios.

[0039] Specifically, such as Figure 1 As shown, the first fixing part includes a first base plate 10. In this embodiment, the first base plate 10 is formed as a cuboid plate structure, and a plurality of first connecting holes are formed on the end face of its first end in the extending direction. Similarly, the second fixing part includes a second base plate 11. In this embodiment, the second base plate 11 is also formed as a cuboid plate structure, and a plurality of second connecting holes are formed on the end face of its first end in the extending direction. It should be noted that there is no specific limitation on the size of the first base plate 10 and the second base plate 11. Preferably, in this embodiment, they are set to the same size to ensure the consistency and stability of the overall structure of the arc extinguishing device, thereby improving the welding quality.

[0040] It should be further explained that the first base plate 10 and the second base plate 11 are detachably connected, meaning the included angle between the first base plate 10 and the second base plate 11 can be flexibly adjusted, and the connection direction of the first base plate 10 and the second base plate 11 is the width direction of the first base plate 10 or the second base plate 11. Furthermore, there are no specific limitations on the number, size, and location of the first and second connecting holes. For example, in this embodiment, two first connecting holes and two second connecting holes are provided, both of which are threaded holes. Further, along the connection direction of the first base plate 10 and the second base plate 11, the first connecting hole is located closer to the second base plate 11, and the second connecting hole is located closer to the first base plate 10, to facilitate a stable connection between the first base plate 10 and the second base plate 11.

[0041] In this embodiment, as Figures 1 to 2 As shown, the fixing assembly also includes a connector 13. The first base plate 10 and the second base plate 11 are detachably connected through a first connecting hole, a second connecting hole, and the connector 13. The connector 13 has multiple connecting parts, and an included angle is formed between any two adjacent connecting parts. Each connecting part has multiple third connecting holes 130 corresponding to the first or second connecting holes. Thus, the first base plate 10 and the second base plate 11 can be detachably connected by bolts corresponding to the first, second, and third connecting holes 130. By connecting the first base plate 10 and the second base plate 11 to different connecting parts, the included angle between them can be adjusted.

[0042] It should be noted that the specific shape and structure of the connector 13 are not fixed. For example, in this embodiment, the connector 13 is formed into a "T" shape, that is, it has three connecting parts, and the included angles between adjacent connecting parts are 180°, 90°, and 90° respectively. Thus, as... Figures 4 to 5 As shown, this arc-extinguishing device is applicable to butt welds without slits, butt welds with slits, and fillet welds with slits.

[0043] In this embodiment, the first fixing part further includes a first fixing clip 20, and the second fixing part further includes a second fixing clip 21. Both are used to stably connect the base material 40 to the first base plate 10 and the second base plate 11 to facilitate welding of the base material 40. The first fixing clip 20 and the second fixing clip 21 are detachably connected to the first base plate 10 and the second base plate 11, respectively. When connected to the first base plate 10 and the second base plate 11, the first fixing clip 20 and the second fixing clip 21 are located at the second ends of the extending directions of the first base plate 10 and the second base plate 11, respectively. However, the specific positions of the first fixing clip 20 and the second fixing clip 21 are not fixed, as long as they can stably clamp the base material 40 to facilitate welding.

[0044] Specifically, in this embodiment, the first fixing clip 20 and the second fixing clip 21 are formed with similar structures, both having a first clamping part 22 and a second clamping part 23. The first clamping part 22 allows the first fixing clip 20 and the second fixing clip 21 to be connected to the first base plate 10 and the second base plate 11 respectively, while the second clamping part 23 stably clamps the mother material 40. More specifically, taking the first fixing clip 20 as an example... Figure 1 and Figure 3 As shown, the first fixing clamp 20 includes two horizontal plates and one vertical plate. The two ends of the vertical plate extending in the direction of extension are connected to the two horizontal plates respectively, so that the first fixing clamp 20 forms an "I"-shaped structure. The first clamping part 22 and the second clamping part 23 are distributed on both sides of the vertical plate extending in the direction of extension, and both are formed into an open structure in the shape of a U. Furthermore, threaded holes are formed at both ends of the two horizontal plates extending in the direction of extension for mounting corresponding studs.

[0045] Thus, by placing the first base plate 10 in the first clamping part 22 and screwing in two studs to abut against the top and bottom of the first base plate 10, a stable connection between the first fixing clamp 20 and the first base plate 10 can be achieved. Similarly, by placing the base material 40 in the second clamping part 23 and screwing in two studs to abut against the top and bottom of the base material 40, a stable connection between the first fixing clamp 20 and the base material 40 can be achieved. It should be noted that the size of the first fixing clamp 20 and the second fixing clamp 21 is not specifically limited, as long as the above-mentioned technical effects can be achieved. The connection positions of the two clamps with the first base plate 10 or the second base plate 11 can also be flexibly determined according to the size of the base material 40.

[0046] In this embodiment, to further improve welding accuracy, the arc ignition and extinguishing device is also provided with a positioning component that is detachably connected to the aforementioned fixing component. For example... Figure 1 As shown, the positioning assembly includes a first arc-extinguishing plate 30 and a second arc-extinguishing plate 31, both of which form a wedge-shaped plate structure. The first arc-extinguishing plate 30 and the second arc-extinguishing plate 31 are detachably connected to the first base plate 10 and the second base plate 11, respectively. An elongated oval-shaped first through hole 32 is formed at the center of each of the first arc-extinguishing plate 30 and the second arc-extinguishing plate 31; an elongated oval-shaped second through hole 12 is formed at the center of each of the first base plate 10 and the second base plate 11. To ensure the stability of the positioning assembly connection, the extension direction of the first through hole 32 is perpendicular to the extension direction of the second through hole 12, that is, the extension direction of the first through hole 32 is the same as the extension direction of the first arc-extinguishing plate 30 and the second arc-extinguishing plate 31, and the extension direction of the second through hole 12 is the same as the connection direction of the first base plate 10 and the second base plate 11. Furthermore, the first through hole 32 and the second through hole 12 are connected by positioning elements, namely bolts and nuts.

[0047] It should be noted that when the base material 40 is connected to the aforementioned fixing assembly, the first arc-extinguishing plate 30 and the second arc-extinguishing plate 31 abut against the base material 40, and the connection between the first arc-extinguishing plate 30 and the second arc-extinguishing plate 31 corresponds to the connection between the two base materials 40 (i.e., the weld). Furthermore, when the base material 40 is welded without opening a section (e.g....), Figure 4 and Figure 6 As shown), the vertical edges of the first arc-extinguishing plate 30 and the second arc-extinguishing plate 31 are close to each other; when the base material 40 is welded with a slit (such as... Figure 5 As shown, the inclined edges of the first arc-extinguishing plate 30 and the second arc-extinguishing plate 31 are close to each other.

[0048] According to the arc ignition and extinguishing device of the present invention, the base material 40 can be detachably connected to a preset position via a fixing component and a positioning component to facilitate welding. Furthermore, the included angle between the first fixing part and the second fixing part in the fixing component is adjustable, thus enabling the device to be flexibly applied to different welding scenarios, such as butt welds without slits, butt welds with slits, and fillet welds with slits. Therefore, the arc ignition and extinguishing device does not require on-site fabrication and can be repeatedly applied to different welding scenarios, effectively improving welding efficiency and reducing labor and material costs. In addition, when welding with the assistance of this arc ignition and extinguishing device, there is no need for spot welding to fix it to the base material 40, thereby effectively ensuring the quality of the base material 40.

[0049] According to a second aspect of the present invention, a welding method is provided for use in the arc ignition and extinguishing device as described above. Specifically, when it is necessary to weld the base material 40, the base material 40 is fixed by the aforementioned fixing component, and the base material 40 abuts against the positioning component; then the base material 40 is welded.

[0050] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
