Description

Technical Field

[0001] The invention relates to the technical field of intelligent welding of steel structures, and in particular to an intelligent welding method for steel structures. Background Art

[0002] With the continuous development of the construction and manufacturing industries, the requirements for steel structures are constantly increasing. In the production process of various steel workpieces, welding technology is particularly important. Through welding, gaps and weaknesses in mechanical connections can be eliminated to form high-strength connections, ensure a firm bond between the various structural components, enhance the stability and bearing capacity of the overall structure, improve the integrity and seismic resistance of the structure, and ensure safety under extreme conditions. Therefore, an intelligent welding method for steel structures is particularly important.

[0003] Traditional steel structure welding methods mainly rely on manual operation by workers. The workers' skill level and experience directly affect the welding quality. Under this model, welding quality often varies due to human factors. For example, in the same batch of production, different workers may have different welding line widths and welding depths due to differences in experience and proficiency, thus affecting the overall welding quality. In addition, the manual welding process is relatively slow and cannot meet the requirements of modern industry for high-efficiency and large-scale production. Especially when it comes to welding large-area steel structures or complex components, manual operation cannot achieve fast, continuous and high-quality welding.

[0004] During the welding process of steel structures, traditional welding methods usually adopt direct cutting in order to adjust the hole positions to avoid welding points. Although this method is simple, it causes a large waste of material utilization. For example, when the hole positions need to be removed or changed, workers often directly cut the steel plates over a large area, resulting in the inability to reuse the scraps of the steel plates. For light or small-sized steel plates, this type of cutting may have limited impact on the overall material cost, but for large, heavy or high-cost steel plate materials, the economic pressure caused by cutting losses cannot be ignored.

[0005] It is a common process to splice several steel plates by welding. However, during the splicing process, the traditional welding method does not fully optimize the splicing method of the steel plates. For example, the hole positions of the steel plates are not accurately measured, which may result in the need for secondary cutting after splicing, further increasing material waste.

[0006] There are a large number of steel structure frames in some existing industrial facilities, which are usually used to support and fix equipment or building components. Welding points are important connection parts in steel structure frames, and their bearing capacity directly affects the stability of the overall structure. However, traditional welding methods usually fail to fully consider the performance of welding points under pressure or dynamic stress conditions, especially in some high-stress areas, such as the support points of bridges or the nodes of high-rise buildings. Insufficient strength of welding points may lead to unstable support, thereby causing the risk of structural deformation, local failure or even overall collapse. Summary of the invention

[0007] The present invention provides an intelligent welding method for steel structure, which is used to promote solving the problems mentioned in the above background technology.

[0065] The present invention has the following beneficial effects:

[0066] 1. This intelligent welding method for steel structures eliminates traditional manual welding and integrates cutting, hole adjustment and welding operations, greatly reducing the time of manual operation and the switching of complex processes, and significantly reducing dependence on manual labor. This integrated automated operation significantly shortens the welding cycle, meets the needs of modern industry for efficient production, and also reduces the efficiency loss caused by manual operation; it also reduces the burden on workers, especially in high-risk environments such as high-altitude operations or high-temperature welding scenarios, and improves the safety of industrial production; and automated welding can maintain stable welding parameters to ensure the consistency of welding quality.

[0067] 2. The intelligent welding method for steel structure determines the order of cutting, punching and welding according to the ratio of D to d D÷d. When D÷d>0.6 or D÷d<0.4, it means that the rectangular hole with a length of Z is completely on the steel plate to be supplemented or the supplementary steel plate. Therefore, when the supplementary steel plate is used to supplement the supplementary steel plate, the welding position will not coincide with the hole position. Therefore, the two processes of cutting, punching and welding do not affect each other, and the steel plate to be supplemented and the supplementary steel plate can be directly welded; when 0.4≤D÷d≤0.6, it means that part of the rectangular hole with a length of Z is At the rear end of the to-be-supplemented steel plate, a part is at the front end of the supplementary steel plate. Therefore, when the supplementary steel plate is used to supplement the to-be-supplemented steel plate, the welding position will coincide with the hole position. Therefore, the two processes of cutting, punching and welding affect each other, and the to-be-supplemented steel plate and the supplementary steel plate cannot be directly welded. The cutting, punching and welding processes are dynamically planned through the ratio of D to d, avoiding repeated adjustment of the hole position or rework. This integrated automated operation significantly shortens the welding cycle, meets the needs of modern industry for efficient production, and also reduces the efficiency loss caused by manual operation.

[0068] 3. This intelligent welding method for steel structures, when the hole position coincides with the welding position, the traditional process usually directly cuts the steel plate, resulting in a large amount of material waste. This solution optimizes the cutting of the steel plate through the ratio D÷d combined with the size of the hole position, which not only improves the material utilization rate but also reduces the waste of resources in the processing process; this cutting position planning ensures the uniformity of the force after the steel plate is spliced, greatly reducing the risk of cracks, deformation or fatigue failure at the weld; compared with the traditional method, this solution ensures the stability of the welding parameters, making the welding quality more controllable and consistent.

[0069] 4. The intelligent welding method for steel structure plans the cutting positions of the rear end and the front end of the supplementary steel plate according to the size of the hole position. The steel plate to be supplemented is cut first, and then the supplementary steel plate is cut twice to ensure that the steel plate to be supplemented and the supplementary steel plate can fit completely when spliced. In addition, the planning of the cutting position intentionally extends the welding line segment of the spliced ​​steel plate to increase the contact area of ​​the welding area, thereby improving the strength of the welded joint and increasing the stability of the connection between the steel plate to be supplemented and the supplementary steel plate after welding, ensuring that the stability and safety will not be affected in the subsequent drilling. This stability guarantee is particularly suitable for steel structure scenes that bear gravity or dynamic stress, such as bridges and towers. BRIEF DESCRIPTION OF THE DRAWINGS

This solution optimizes the cutting of the steel plate through the ratio D÷d and the size of the hole, which not only improves the material utilization rate but also reduces the waste of resources in the processing process. This planning of the cutting position ensures the uniformity of the force on the steel plates after splicing, and greatly reduces the risk of cracks, deformation or fatigue failure at the weld.
