Description

Technical Field

[0001] The embodiments of the present disclosure belong to the technical field of automated welding, and specifically relate to an automatic matching system for high-strength steel welding processes. Background Art

[0002] Welding is the process of connecting two or more workpieces together by melting metal or non-metallic materials. In particular, there are many types of high-strength steel welding processes, each of which has its specific application scenarios and advantages. The current high-strength steel welding process is to classify high-strength steel materials, manually select the most suitable and economical welding process, and perform welding manually, but this method has the following disadvantages:

[0003] 1. Manual selection of high-strength steel welding process by classification of high-strength steel materials has the problem of low matching between high-strength steel materials and welding process. The selection depends entirely on manual work experience. Although the high-strength steel welding process selected by experienced manual workers has a high matching degree, the labor cost is relatively high. Especially in the case of scarcity of skilled and experienced welders, the labor cost has become an important factor restricting the development of enterprises. The probability of errors in the matching degree between high-strength steel materials and high-strength steel welding processes by manual workers with relatively low experience is relatively high;

[0004] 2. The welding quality of high-strength steel is unstable. Due to the uncertainty of manual operation, the welding quality is often difficult to maintain consistency. It is difficult to accurately control the relevant parameters of the welding process, which can easily lead to problems such as weld cracking, pores, and undercuts, thereby reducing the strength and toughness of the joint. Especially in large-scale or high-precision production, welding processes based on manual welding experience are difficult to meet the requirements of quality stability and reliability; Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1This is a schematic block diagram of an automatic matching system for high-strength steel welding processes according to an embodiment of the present disclosure. DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1 As shown, a high-strength steel welding process automatic matching system 100, the automatic matching system 100 includes an input module 110, a matching analysis module 120 and an automatic welding module 130. The input module 110 is used to input data information of high-strength steel. The matching analysis module 120 is used to perform information matching according to the data information, obtain the welding process corresponding to the high-strength steel, and determine the required welding rod model according to the welding process. The automatic welding module 130 is used to determine the welding position of the high-strength steel according to the data information, and call a grinder to grind the welding position. The automatic welding module 130 is also used to control the clamping and docking of two high-strength steels that have been polished on the welding table, and weld the welding positions of the two high-strength steels after clamping and docking by adopting the corresponding welding process and the determined welding rod.

[0026] Specifically, Figure 1 As shown, the data information of high-strength steel is input through the input module 110, and the data information of high-strength steel includes the material, size, welding gap size and welding port shape of high-strength steel. The matching analysis module 120 matches the input high-strength steel data information, such as the material, size and welding gap size of the high-strength steel, to obtain the welding process corresponding to the high-strength steel. The welding process includes welding current, arc voltage, welding speed and number of welding layers. Select a suitable welding current according to the size of the welding gap of high-strength steel to ensure the quality of the weld and welding efficiency. The arc voltage and welding current jointly affect the welding heat input and are adjusted as needed. Controlling the welding speed can ensure the quality and flatness of the welds between high-strength steels. Too fast or too slow may result in a decrease in weld quality. For the number of welding layers, if the high-strength steel is thicker, multi-layer and multi-pass welding may be required, and the parameters of each layer of welding may also be different.

[0027] The matching analysis module 120 will also determine the required welding rod model according to the welding process, prepare the welding process, and the process will simultaneously simulate the welding process. The determined welding rod is then used for welding. The automatic welding module 130 is used to determine the welding position of the high-strength steel according to the shape of the welding port of the high-strength steel. The welding positions include flat welding, vertical welding and overhead welding, etc. Different welding positions have an impact on welding parameters and welding methods. After determining the welding position, the automatic welding module 130 will also call a grinder to grind the welding position, remove the surface covering of the high-strength steel welding position, and prepare for welding.

[0028] The automatic welding module 130 also controls the two high-strength steels that have been polished on the welding table to be clamped and butted, and welds the welding positions of the two high-strength steels after clamping and butting by using the corresponding welding process and the determined welding rods.

[0029] The high-strength steel welding process automatic matching system of the embodiment of the present disclosure can automatically select the appropriate welding process and welding rod according to the input high-strength steel data information, thereby ensuring the stability and consistency of welding quality and improving the welding quality and efficiency of high-strength steel. In addition, there is no need for welders to manually calculate and set welding parameters, avoiding welding defects and safety accidents caused by improper parameter settings, while also reducing the difficulty of operation and skill requirements, making welding work simpler and more efficient, further reducing the need for manual intervention, reducing labor costs, and saving human resources for enterprises.

[0030] For example, after welding is completed, the automatic welding module is also used to call the grinder to clean the welding beads at the welding position, thereby optimizing the welding results. The automatic welding module is also used to control the smoke exhaust and dust removal equipment to remove the smoke and dust in the welding room, which can effectively reduce the emission of pollutants such as welding smoke and harmful gases, and improve the environmental protection of welding.

[0031] For example, Figure 1 As shown, the automatic matching system 100 further includes an imaging analysis module 140. The imaging analysis module 140 is used to photograph the welding position after the welding is completed, and determine whether the welding is qualified through imaging.

[0032] Furthermore, the automatic matching system 100 also includes a database module 150 storing a plurality of high-strength steel welding processes, and the database module 150 is electrically connected to the input module 110, the matching analysis module 120 and the automatic welding module 130. If the welding is qualified, the database module 150 will record the process data of the welding process to increase the case data of the database module 150. If the welding is unqualified, the corresponding welding process and the required welding rod model will be re-determined by the matching analysis module 120, and the welding will be re-performed by the automatic welding module 130.

[0033] Specifically, Figure 1 As shown, if the imaging analysis module 140 determines that the welding is qualified, the database module 150 will record the process data of the welding process to increase the case data of the database module 150. If the imaging analysis module 140 determines that the welding is unqualified, the matching analysis module 120 will re-determine the corresponding welding process and the required welding rod model, and prepare the welding process. The process will also simulate the welding process simultaneously. The determined welding rod will be used for welding work later.

[0034] The automatic welding module 130 re-determines the welding position of the high-strength steel according to the shape of the welding port of the high-strength steel. After determining the welding position, the automatic welding module 130 uses a grinder to grind the welding position, removes the outer surface covering of the high-strength steel welding position, and prepares for welding. The automatic welding module 130 also controls the two high-strength steels that have been ground on the welding table to be clamped and butt-jointed, and welds the welding positions of the two high-strength steels after clamping and butt-jointing by using the corresponding welding process and the determined welding rod.

[0035] After welding is completed, the welding position is photographed through the imaging analysis module 140, and the imaging is used to determine whether the welding is qualified. If the imaging analysis module 140 determines that the welding is qualified, the database module 150 will record the process data of the welding process to increase the case data of the database module 150. If the imaging analysis module 140 determines that the welding is unqualified, the corresponding welding process and the required welding rod model are re-determined through the matching analysis module 120, and the welding is re-performed through the automatic welding module 130. Repeat the above process until the welding is qualified. It should be noted that the high-strength steel welding process stored in the database module 150 can be adjusted at any time to change parameters to meet different production needs.

[0036] The high-strength steel welding process automatic matching system of the embodiment of the present disclosure can determine whether the welding is qualified through the imaging analysis module. By changing the stored data in the database module, the parameters can be adjusted at any time to meet various production needs;

[0037] And, by using the cooperation of the input module 110, the matching analysis module 120 and the automatic welding module 130, the corresponding welding process and welding rod model can be automatically selected according to the input high-strength steel data information, and automatic welding can be completed, thereby ensuring the stability and consistency of welding quality and improving the welding quality and efficiency of high-strength steel. The matching analysis module 120 is used for information matching, and the automatic welding module 130 is automatically operated. The welder no longer needs to manually calculate and set welding parameters, which reduces the difficulty of operation and skill requirements, making the welding work simpler and more efficient. The matching analysis module 120 automatically matches the corresponding welding process, reduces the need for manual intervention, reduces labor costs, and saves human resources for the enterprise. It can also effectively avoid welding defects and safety accidents caused by improper parameter settings. The automatic control of the automatic welding module 130 can not only complete the welding work, but also control the corresponding equipment to reduce the emission of pollutants such as welding smoke and harmful gases, and improve the environmental protection of welding.

[0038] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present disclosure, but the present disclosure is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and substance of the present disclosure, and these modifications and improvements are also considered to be within the scope of protection of the present disclosure.
