[0029] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0030] The following is based on the attached Figure 1 The tooling for improving the quality of butt seam welding provided by the utility model is introduced. The tooling for improving the quality of butt seam welding can be applied to welding processes in the field of shipbuilding, and can also be applied to welding processes in other fields. For the convenience of explanation, in the utility model, the tooling for improving the quality of butt seam welding is introduced by taking the butt welding of pipes in the field of shipbuilding as an example. However, introducing the tooling for improving the quality of butt seam welding by taking the butt welding of pipes in the field of shipbuilding as an example does not constitute a specific limitation on the applicable field of the tooling for improving the quality of butt seam welding. Those skilled in the art can apply the tooling for improving the quality of butt seam welding to different specific technical fields within a reasonable range.

[0031] Specifically, Figure 1 As shown, in this embodiment, the tooling for improving the quality of seam welding includes a windproof component and a fixing component. The windproof component is used to isolate the wind and foreign matter carried in the wind from the weld, thereby preventing the wind from affecting the welding quality and preventing problems such as pores and hydrogen embrittlement at the weld. The fixing component is used to fix and fit the windproof component to the pipe to be welded, thereby preventing the windproof component from moving due to wind during welding, thereby avoiding negative impact on the welding process.

[0032] More specifically, continue to refer to Figure 1 As shown, the windproof assembly includes at least two windproof panels, which can be enclosed to form a windproof structure. The windproof structure has and only has two openings, one of which can be attached to the weld to be welded, and the other opening is used for the welding gun to be inserted for welding operation.

[0033] Exemplarily, in the present embodiment, the windproof assembly includes a first windproof plate 1, a second windproof plate 2, a third windproof plate 3 and a fourth windproof plate 4, a total of four windproof plates, and the four windproof plates are connected end to end in sequence, thereby forming a windproof structure with a rectangular cross-section. When the windproof assembly is attached to the outer peripheral surface of the pipeline through the fixing assembly, the four windproof plates can prevent the airflow from flowing directly to the weld along the circumferential direction and axial direction of the pipeline, thereby blocking the wind. At this time, one end opening of the windproof structure is attached to the weld (i.e., the joint of the two pipes), and the welding gun can extend into the windproof structure from the other end opening, and weld the joint of the two pipes.

[0034] By using the above-mentioned tooling for improving the quality of butt seam welding, the windproof component is fixed by a fixing component, and the windproof structure is formed by the windproof component, so that the airflow is blocked by the windproof structure, and the weld to be welded is formed with a wind-blocking effect, avoiding the generation of pores, hydrogen embrittlement and other problems at the welding point, thereby ensuring the welding quality, and further ensuring the safety and service life of the ship.

[0035] Preferably, for butt welding of pipelines, among the above-mentioned four windproof panels, two windproof panels arranged along the axial direction of the pipeline (i.e., the first windproof panel 1 and the second windproof panel 2 shown in the figure) are bent panels. The bent panel is a C-shaped bent structure, and along the radial direction of the pipeline, one side of the bent panel can fit the outer peripheral surface of the pipeline to prevent airflow from entering the windproof structure between the bent panel and the pipeline, which has a negative impact on the welding process and welding quality, leading to problems such as pores and hydrogen embrittlement, and even further affecting the safety and service life of the ship.

[0036] Continue to refer to Figure 1 As shown, in this embodiment, the fixing assembly includes a first tie 5 and a second tie. One end of the first tie 5 and one end of the second tie are respectively connected to the windproof assembly, and the other end of the first tie 5 and the other end of the second tie can be detachably connected. When in use, the windproof assembly is first attached to the outer peripheral surface of the pipe, and then the first tie 5 and the second tie are attached and extended along the outer peripheral surface of the pipe, so that the other end of the first tie 5 and the other end of the second tie are connected after bypassing the pipe, so that the windproof assembly can be tied and fixed to the pipe.

[0037] The fixing assembly further includes a fixing screw 6, which can pass through the other end of the first tie 5 and be threadedly connected to the other end of the second tie to connect the other end of the first tie 5 with the other end of the second tie. Preferably, at least one of the first tie 5 and the second tie adopts a retractable structure, that is, the length between the two ends of the tie is adjustable, so as to adapt to the bundling and fixing of pipes with different diameters.

[0038] Optionally, the butt seam welding quality improvement tool includes two fixing components, one of which is used to fix one of the two pipes to be welded, and the other fixing component is used to fix the other of the two pipes to be welded. By fixing the two pipes respectively with the two fixing components, the two pipes and the butt seam welding quality improvement tool can be fixedly connected, thereby reducing the movement and vibration of the pipes during the welding process and improving the welding quality.

[0039] Optionally, in some embodiments, the fixing assembly includes a first clamping rod, a second clamping rod and a third clamping rod, one end of the first clamping rod and one end of the second clamping rod are respectively connected to the windproof assembly, and the third clamping rod is detachably inserted through the other end of the first clamping rod and the other end of the second clamping rod to fix the first clamping rod and the second clamping rod in connection. The other end of the first clamping rod or the other end of the second clamping rod can be fixedly arranged on the third clamping rod in an adjustable position. When in use, by adjusting the connection position between the other end of the first clamping rod or the other end of the second clamping rod and the third clamping rod, the first clamping rod and the second clamping rod can clamp the pipe. Compared with the above-mentioned bundling fixation, the clamping fixation method can better and more firmly fix the two pipes and the butt seam welding quality improvement tooling to connect, and achieve the effect of more stably fixing the pipe, thereby ensuring the quality of welding.

[0040] In some other embodiments, the windproof assembly includes at least two flexible connectors and at least four windproof panels, wherein at least four windproof panels are the above-mentioned curved panels. The curved panels are arranged along the axial direction and the circumferential direction of the pipeline, and along the circumferential direction of the pipeline, at least one flexible connector is connected between two adjacent curved panels, so that the distance between the two curved panels connected to the flexible connector can be adjusted.

[0041] For example, in this embodiment, the curved plate is made of stainless steel and the flexible connector is made of fluororubber. When the butt seam welding quality improvement tool is moved from a pipeline with a larger diameter and installed to a pipeline with a smaller diameter, the gap between the curved plate and the outer peripheral surface of the pipeline can be minimized by bending the flexible connector around the axis of the pipeline, thereby preventing airflow from entering the windproof structure from between the curved plate and the pipeline, which has a negative impact on the welding process and welding quality, leading to problems such as pores and hydrogen embrittlement, and even further affecting the safety and service life of the ship.

[0042] It can be understood that the more bent plates and flexible connectors are set along the circumferential direction of the pipeline, the larger the pipe diameter range that the butt seam welding quality improvement tooling can adapt to, and the higher the degree of fit to the outer surface of the pipeline, the better the adaptability and wind resistance.

[0043] Specifically, in this embodiment, fixing holes are provided at both ends of the flexible connector along the circumferential direction of the pipeline, and connecting screws are installed on the curved plate. The windproof assembly also includes a connecting nut, and the connecting screw passes through the fixing hole and is threadedly connected with the connecting nut to connect the flexible connector and the curved plate. The connecting screw and the connecting nut have the effect of fixing the flexible connector and the windproof plate, and the bending is achieved by the deformation ability of the flexible connector itself.

[0044] Furthermore, along the circumferential direction of the pipeline, at least one flexible connector is provided at each end of the windproof component, and each flexible connector is connected between the two windproof panels along the axial direction of the pipeline. Through the flexible connector, the distance between the two windproof panels can be adjusted along the axial direction of the pipeline, thereby adjusting the size of the opening. When the wind force in the environment is strong, by bending and twisting the flexible connector (in a different direction from the above-mentioned bending) so that one side of the surface is convex, the distance between the two ends of the flexible connector can be shortened, the opening can be reduced, and airflow can be prevented from entering through the opening. When the wind force in the environment is strong, the flexible connector can be restored to be flat, and the distance between the two ends of the flexible connector can be restored to the normal opening size, which is convenient for welding operations.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
