  The weld height is the height of that portion of the metal on the surface of the weld above the line of the two toes. In layman's terms, the residual height refers to the portion of the weld metal that bulges out of the surface of the base metal or the portion of the molten metal that is above the line of connection at the end of the fillet weld (i.e., the toe).   The residual height increases the cross-sectional area and strength of the weld, which can increase the sensitivity of X-ray radiography, but it is easy to cause stress concentration at the weld toe, so the residual height should not be lower than the base material, but also not too high. According to national standards, the residual height of manual electric arc welding is 0 mm ~ 3 mm, and the residual height of submerged arc welding is 0 mm ~ 4 mm.   In practice, the size and shape of the weld residual height will have an effect on the performance of the welded joint, so it is very important to control the w...

  How to choose the right steel structure material ? Choosing the right material for your steel structure is a comprehensive process that requires consideration of several factors. Here are some suggestions: Understand the performance of the material: different steel structure materials have different properties, such as strength, stiffness, toughness, corrosion resistance, fire resistance, and so on. When choosing materials, you need to select materials with performance that meets the requirements according to the actual needs and use environment. Consider load and span: The load and span of steel structure are important factors affecting material selection. For large span and heavy load steel structures, it is necessary to choose high strength and high stiffness materials to ensure the safety and stability of the structure. Environmental factors: Environmental factors also have an impact on material selection. For example, in humid and corrosive environments, materials with goo...

  Welding rods are welding materials used for manual arc welding and usually contain a welding core and flux. Different types of welding rods are used for different welding tasks and materials. The following are some common types of welding rods: Carbon Steel Welding Rods: Suitable for welding carbon steel and commonly used in general structural and manufacturing applications. Good general performance. Stainless steel electrodes: Used for welding stainless steel materials to prevent oxidation and corrosion. Divided into 309, 310, 316 and other different grades.   Aluminum welding rod: specifically for aluminum and aluminum alloy welding, there are different grades, such as 4043 and 5356, applicable to different types of aluminum alloy.   Nickel alloy welding electrodes: used for welding nickel-based alloys, such as Inconel and Hastelloy, etc., suitable for high temperature and corrosive environments. Copper alloy electrodes: suitable for welding brass and copper alloys, u...

There are various types of welding electrodes commonly used in the welding of steel structures and the choice depends on the specific application and requirements.  The following are some of the types of welding electrodes commonly used in structural steel welding:   General purpose carbon steel electrodes: Used for welding general carbon steel structures, these electrodes are suitable for most construction welding tasks.   Low alloy electrodes: for welding low alloy steel structures to improve the strength and corrosion resistance of welded joints.   Stainless steel electrodes: Used for welding stainless steel structures to ensure that the weld has corrosion and oxidation resistance.   Hardfacing electrodes: Used for wear and impact-resistant applications such as excavator blades, mining equipment, etc.   Weathering steel electrodes: For welding weathering steel, is often used in outdoor structures such as bridges and buildings.   High Strength Weld...

There are three main installation methods for steel structure pre-embedded parts: pre-embedded parts Bolt connection method: it is suitable for steel structure pre-embedded parts with smaller sizes or simpler specifications. This method has the advantages of simplicity ease of installation and fast installation speed. Welding connection method: applicable to steel structure embedded parts with larger size or more complex specifications. This method has the advantages of firm connection and good stability. However, welding requires a certain level of skill and requires experienced welders to operate. Presetting method: In some construction projects, the installation position of steel-embedded parts can be reserved in advance when the concrete is poured, and the installation can be carried out directly after the concrete is solidified. This method can reduce the damage to the concrete structure and improve the integrity of the building.  💗💗💗💗💗💗 Explore the endless possibilities...

Most of the stadium stands are made of truss , mainly because truss has the following advantages:   l High structural strength: truss consists of a triangular grid formed by multiple straight lines and has a stable structure that can bear the weight of a large number of spectators while resisting wind and other natural forces. l Aesthetic design: trusses have a special shape that creates a stunning visual effect, adding an aesthetic and unique look to the stadium, making it one of the iconic elements. l Maintaining Views: Trusses are often installed in front of or on top of the spectator stands to minimize disruption to the viewing experience. l Convenient construction: trusses are easy to design, fabricate and install, and adapt to a wide range of spans, so they are very widely used. l Economy: The steel consumption of truss is more economical, and the cost is lower compared with other structural forms. To summarize, most of the stadium grandstands choose truss , mainly because tr...

  Connection construction methods for steel buildings The steel structure building connection construction mainly consists of three ways: rivet connection, welding, bolt connection. 1. Rivet connection Rivet connection refers to the connection method of inserting rivets into the rivet holes and then riveting the holes together by applying pressure or heating, and the internal part of the member is pressurized by the shear of the rivets. The advantages of riveting are reliable force transmission, good shape and toughness. The disadvantage is that the rivet processing and manufacturing of steel consumption, riveting procedures are complex, and processing and manufacturing labor-intensive, limited bearing capacity, in the rivet hole will produce strong stress. Rivet connection 2. Welding technology Welding is the most common connection form for basic steel structure components. Welding generally does not require splicing materials, saving steel and labor, saving materials; good seali...
