Description

Technical Field

[0001] This utility model relates to the field of welding stud technology, specifically to an integrated aluminum welding stud. Background Technology

[0002] The prototype of stud welding technology originated in 1918 at the British shipyard, Booz Maas. Engineers Stiller and Martin first attempted to weld specially treated copper parts directly onto steel components, skipping the steps of traditional riveting or bolting. While this innovation did not immediately become widespread, it laid the foundation for stud welding technology. In 1935, American Nelson further experimented with this technique in the construction of warship decks: he welded surface-treated steel studs onto deck steel sections, then secured pre-drilled wooden floor strips with nuts. This "electrode-free welding" method was named electric arc stud welding and is still used today. The core of stud welding lies in the arc's thermal melting effect. During operation, the stud is held in a special welding torch, and its end contacts the base material (such as steel plate) before an arc is ignited. The instantaneous high temperature generated by the arc melts the stud end and the surface of the base material. Subsequently, the welding torch automatically applies pressure to melt the molten material. The metal is compacted to form a weld. This process is completed within 0.1 seconds, achieving full-section fusion between the stud and the base material, with a connection strength approaching that of the base material itself. The commercialization of stud technology began in the 1950s, initially primarily for shipbuilding and bridge construction. In the 1980s, a surge in demand for infrastructure construction led to a period of rapid development for the stud industry. In 1985, the Ministry of Metallurgical Industry initiated a project to promote the localization of cylindrical head studs, and companies such as Tianjin Standard Parts Factory No. 3 achieved large-scale production, with applications covering pillar industries of the national economy such as construction, energy, and transportation.

[0003] After traditional welding studs are welded, the ceramic sleeves attached to them need to be removed, which is usually done by smashing them. This not only increases production costs but also greatly affects work efficiency.

[0004] In view of this, this application proposes an aluminum integral welding stud. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated aluminum welding stud, which solves the problem that after welding, the ceramic sleeve of the traditional welding stud needs to be removed, which is usually done by smashing it. This not only increases production costs but also greatly affects work efficiency. The technical solution adopted by this utility model is as follows:

[0006] An integrated aluminum welding stud includes a welding rod and a ring assembly. The ring assembly is located at the lower end of the welding rod. The ring assembly includes a first ring cover, a second ring cover, and a slider. The first ring cover has a semi-circular cavity and a semi-circular groove. The second ring cover is installed in the semi-circular cavity. The slider is installed in the semi-circular groove. The slider is fixedly connected to the second ring cover.

[0007] Using the above technical solution, when welding studs is required, one hand holds the first ring cover, while the other hand slides the second ring cover. Because the second ring cover is slidably connected to the first ring cover, and the slider is fixedly connected to the first ring cover and installed in the semi-circular groove, the second ring cover will slide along the semi-circular cavity, eventually closing the ring sleeve. The ring sleeve is then placed at the welding location. The bottom end of the welding rod passes through the circular hole in the ring sleeve assembly, and welding is performed using a welding torch. After welding is completed, the first ring cover is moved, causing the second ring cover to move into the first sliding cover, and then the ring sleeve assembly is removed. This significantly improves the cost and efficiency of stud welding.

[0008] A further improvement of this utility model is that it also includes a welding cap. The welding cap is fixedly connected to the top of the welding rod.

[0009] A further improvement of this utility model is that it also includes an anti-slip layer. The anti-slip layer is fixedly installed on the outside of the welding cap.

[0010] By employing the above technical solution, the anti-slip layer significantly increases the friction between the weld stud and other objects, ensuring the stud remains stable and does not easily slip during welding. This helps to form a more uniform and robust weld, thereby improving the quality and strength of the welded joint and reducing welding defects.

[0011] A further improvement of this utility model is that the welding cap has a groove.

[0012] In the above technical solution, the groove is used to identify the model number.

[0013] A further improvement of this utility model is that the diameter of the welding rod is smaller than the inner diameter of the ring assembly in the open state.

[0014] A further improvement of this utility model is that it also includes an arc-starting body. The arc-starting body is fixedly installed at the bottom end of the welding rod.

[0015] The above technical solution uses an arc-igniting body to help the electric arc ignite stably between the welding stud and the base material, thereby reducing the generation of welding defects.

[0016] A further improvement of this utility model is that the welding rod has a cavity.

[0017] A further improvement of this utility model is that the cavity structure can significantly reduce the overall weight of the welding stud, making the welding stud more convenient to transport, store and use.

[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0019] 1. This utility model provides an integrated aluminum welding stud. When welding the stud is required, the second ring cover slides. Because the second ring cover is slidably connected to the first ring cover, and the slider is fixedly connected to the first ring cover and installed in a semi-circular groove, the second ring cover slides along the semi-circular cavity, eventually closing the ring sleeve. The ring sleeve is then placed at the welding location. The bottom end of the welding rod passes through the circular hole of the ring sleeve assembly for welding. After welding is completed, the first ring cover is moved, causing the second ring cover to move into the first slider cover. Then, the ring sleeve assembly is removed, greatly improving the cost of the welding stud and the welding efficiency.

[0020] 2. This utility model provides an integrated aluminum welding stud. The cavity provided in the welding rod can significantly reduce the overall weight of the welding stud, making the welding stud more convenient to transport, store and use. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to embodiments:

[0030] Example 1

[0031] like Figures 1-6 As shown, this utility model provides an integrated aluminum welding stud, including a welding rod 1, a welding cap 3, a ring assembly 2, and may also include an anti-slip layer 4 and an arc-starting body 7.

[0032] The lower end of the welding rod 1 is provided with a ring assembly 2. The ring assembly 2 includes: a first ring cover 21, a second ring cover 22, and a slider 23. The first ring cover 21 has a semi-circular cavity 24 and a semi-circular groove 25. The second ring cover 22 is installed in the semi-circular cavity 24. The slider 23 is installed in the semi-circular groove 25. The slider 23 is fixedly connected to the second ring cover 22. The welding cap 3 is fixedly connected to the top end of the welding rod 1. The diameter of the welding rod 1 is smaller than the inner diameter of the ring assembly 2 in the open state. When welding is required, hold the first ring cover 21 with one hand and slide the second ring cover 22 with the other hand. Because the second ring cover 22 is slidably connected to the first ring cover 21, and the slider 23 is fixedly connected to the first ring cover 21 and installed in the semi-circular groove 25, the second ring cover 22 will slide along the semi-circular cavity 24, eventually closing the ring. Then, place the ring on the place where welding is required. Pass the bottom end of the welding rod 1 through the circular hole of the ring assembly 2 for welding. After welding is completed, the first ring cover 21 is moved, allowing the second ring cover 22 to move into the first sliding cover. Then, the ring sleeve assembly 2 is removed, significantly improving the cost and efficiency of welding studs. The ring sleeve assembly 2 reduces the loss of arc heat, concentrating heat in the welding area, improving welding efficiency, protecting the molten pool during welding, reducing the heat-affected zone, and lowering the risk of base material deformation. It also reduces spatter damage to equipment and personnel, and facilitates cleaning and maintenance. The weld cap and weld helmet 3 can be made of aluminum, which has good plasticity and toughness, allowing it to withstand certain deformations without breaking during welding. Weld studs are commonly used in applications requiring high-strength connections, such as steel structures, bridges, automotive manufacturing, and aerospace. These applications place high demands on the mechanical properties, weldability, and corrosion resistance of the studs. Aluminum has only about one-third the density of steel, making aluminum welding studs lighter than traditional steel studs. This helps reduce the overall structural weight, improve fuel efficiency, and lower transportation costs. Aluminum has good corrosion resistance and oxidation resistance, maintaining stable performance in humid and corrosive environments. This helps extend the lifespan of welding studs and reduces the frequency of maintenance and replacement. Aluminum's high thermal and electrical conductivity facilitates rapid heat dissipation during welding, reducing the heat-affected zone and lowering the risk of base material deformation. Good electrical conductivity also contributes to improved welding efficiency and quality. Aluminum is easily manufactured into various shapes of welding studs through casting, forging, and machining processes. Furthermore, aluminum is recyclable, helping to reduce production costs and environmental pollution.

[0033] The replacement sleeve assembly can be made of stainless steel, a material with excellent high-temperature resistance, maintaining stable physical and chemical properties even at high temperatures. During welding, stainless steel must withstand the burning of a high-temperature electric arc. It better resists high-temperature deformation and oxidation, ensuring stable shape and performance over long-term use, thus extending its service life. Stainless steel also possesses high mechanical strength, capable of withstanding significant external forces and impacts. During welding, it may be subjected to mechanical vibrations, collisions, and other external forces; stainless steel better resists these forces, reducing the risk of damage to the ceramic sleeve. Stainless steel exhibits good resistance to acids, alkalis, and other chemicals, maintaining stable performance even in corrosive environments. During welding, it better resists the corrosion of other chemicals, extending its service life. Stainless steel has good thermal and electrical conductivity, enabling faster heat and current transfer, which helps form a more uniform and stable molten pool during welding. This contributes to improved weld joint quality and strength, reducing welding defects. Simultaneously, the smooth surface of stainless steel helps reduce spatter and impurities during welding, further improving weld quality. Stainless steel is easily manufactured into ceramic sleeves of various shapes through processes such as casting, forging, and machining. This helps reduce the processing difficulty and cost of ceramic sleeves, and improves production efficiency. Stainless steel is a recyclable material, which helps reduce environmental pollution and resource waste. Using stainless steel to make ceramic sleeves not only aligns with the concepts of environmental protection and sustainable development, but also helps reduce production costs and social responsibility risks for enterprises.

[0034] The anti-slip layer 4 is fixedly installed on the outside of the welding cap 3. The anti-slip layer 4 significantly increases the friction between the welding stud and other objects, ensuring the stud remains stable and does not easily slip during welding. This helps form a more uniform and stronger weld, thereby improving the quality and strength of the weld joint and reducing welding defects. If the welding stud slips during welding, it may cause problems such as arc deviation and uneven weld, increasing operational difficulty and danger. The use of the anti-slip layer 4 effectively reduces the risk of stud slippage, making welding operations more stable and safer, and reducing the possibility of accidents. The anti-slip layer 4 can be made of ceramic particles, which have extremely high hardness, creating numerous tiny protrusions and grooves 5 on the surface of the anti-slip layer 4, significantly increasing the coefficient of friction between the welding stud and the object. This ensures the stability and accuracy of the welding process. Alternatively, the anti-slip layer 4 can be made of rubber material, which has a high coefficient of friction, providing good grip and effectively preventing slippage. Its surface texture and elastic properties increase friction with the contact surface, ensuring a stable anti-slip effect under various conditions. The rubber material also has excellent wear resistance, resisting mechanical wear and friction. Rubber maintains its anti-slip properties for extended periods, reducing performance degradation due to wear. Its excellent elasticity allows it to adapt to various shapes and surfaces. This elasticity enables it to better conform to contact surfaces, providing a more uniform anti-slip effect and reducing stress concentration. Rubber is resistant to a variety of chemicals, including acids, alkalis, and oils. This allows it to be used in harsh chemical environments without being damaged by corrosion. Rubber is easily processed into various shapes and sizes through extrusion, molding, and other processes. This allows for customized production to meet the needs of different applications. Installation is also relatively simple, using methods such as adhesive bonding and bolting. Rubber is relatively inexpensive and recyclable, contributing to reduced production costs and environmental pollution. Using rubber is not only economical and practical but also aligns with the principles of sustainable development.

[0035] The welding cap 3 has a groove 5. The arc-starting body 7 is fixedly installed at the bottom end of the welding rod 1. The welding rod 1 has a cavity 6. The groove 5 on the welding cap 3 is used to indicate the model. At the start of welding, the arc-starting body 7 helps to stably ignite the arc between the welding stud and the base material, which is crucial to ensuring welding quality. The arc-starting body 7 can maintain the stability of the arc and prevent the arc from going out or shifting during welding. A stable arc is the basis for forming a good weld, ensuring uniform distribution of welding heat and reducing the generation of welding defects. The arc-starting body 7 helps to concentrate the heat generated by the arc, making it act more accurately on the welding area, improving welding efficiency, while reducing the range of the heat-affected zone and helping to maintain the properties of the base material. The arc-starting body 7 can reduce welding defects such as porosity and cracks, thereby improving welding quality. The cavity 6 can significantly reduce the overall weight of the welding stud, making the welding stud more convenient to transport, store and use. For welding operations that require a large number of welding studs, this advantage not only reduces labor intensity but also improves work efficiency. At the same time, the cavity 6 also helps to reduce the overall load on the welding equipment and extend the service life of the equipment. By precisely controlling the size and position of cavity 6, welding stud manufacturers can minimize material usage while ensuring welding performance. This not only improves material utilization but also reduces production costs. For users, this means achieving high-quality welding results at a more economical price.

[0036] The working principle of this type of integrated aluminum welding stud will be explained in detail below.

[0037] like Figures 1-6 As shown, when welding the stud, one hand holds the first ring cover 21, while the other hand slides the second ring cover 22. Because the second ring cover 22 is slidably connected to the first ring cover 21, and the slider 23 is fixedly connected to the first ring cover 21 and installed in the semi-circular groove 25, the second ring cover 22 slides along the semi-circular cavity 24, eventually closing the ring. The ring is then placed on the area to be welded. The bottom end of the welding rod 1 passes through the circular hole of the ring assembly 2, and welding is performed using a welding torch. After welding, the first ring cover 21 is moved, causing the second ring cover 22 to move into the first slider, and then the ring assembly 2 is removed. This significantly improves the cost and efficiency of the welding stud. In summary, this welding stud is convenient and flexible.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
