There are many things to note during the welding process of steel structures. Once overlooked, it may lead to major mistakes. Today, I have compiled some frequently overlooked matters during steel structure welding for you. Don't take it lightly! Welding construction does not pay attention to the phenomenon of choosing the best voltage and its hazards. Whether it is the bottom, filling, or surfacing, regardless of the size of the bevel, the same arc voltage is selected during welding. This may not reach the required penetration depth and width, resulting in defects such as undercutting, porosity, and spatter. Preventive measures Generally, different arc lengths should be selected for different situations to obtain better welding quality and work efficiency, such as for the bottom layer.

In the modern building market, the rise of steel structure engineering has greatly promoted modern architecture. The reduced application range and construction time of steel structure buildings have been favored by many construction projects. Many factories use steel structure buildings, and public awnings are now also built with steel structures. Therefore, steel structure design has received everyone's attention. Let's talk about the methods of steel structure design below. The probability limit state design method is the basic method of engineering structure design in China and also the basic method of steel structure design. If the structure exceeds a certain specific state, it cannot meet the design requirements.

A steel structure residential project, jointly developed and produced by a certain construction engineering company and Jilin Jianzhu University, officially commenced its main structure hoisting and installation on May 30 in the courtyard of Yu Xin Group in the Changchun Automotive Industry Development Zone. Li Baozheng, the vice general manager of the construction engineering company, introduced that steel structure residential buildings use steel as the load-bearing beams and columns. Its advantages include light weight, high strength, and about half the weight of reinforced concrete residential buildings. It meets the needs of large residential spans, with a usable area about 4% higher than reinforced concrete residential buildings. It also boasts good earthquake resistance, insulation, waterproofing, and sound insulation performance. Steel structure components are factory-produced...

A new building system has the potential to break down the industry boundaries between the real estate, construction, metallurgical, mechanical equipment manufacturing, and national strategic resource industries, combining them into a new industrial system. This is the steel structure building system that is widely favored by industry insiders. This was stated by Fang Hongqiang, President of the Zhejiang Provincial Steel Structure Industry Association and Chief Engineer of Hangzhou Jia Design Group Co., Ltd., in his keynote speech on Steel Structure and Green Building at the 11th National Academic Symposium on Modern Structural Engineering.

Recently, the Ping An Finance Centre, the second tallest building in the world and the tallest in China, has reached the 88th floor, exceeding 410 meters in height. The building, which is general contracted by China Construction First Engineering Bureau (Group) Co., Ltd. and has its steel structure constructed by China Construction Steel Structure Co., Ltd., forms a stunning skyline alongside Shenzhen’s Di Wang Building and Kingkey 100. It is understood that the steel structure of Ping An Finance Centre uses approximately 100,000 tons of steel, four times that of the Shenzhen Di Wang Building. Construction is currently proceeding at a rapid pace, with floors being completed as quickly as every four days. As the building continues to rise, it is expected to surpass 450 meters by late June 2014.

[Core Tip] Topics such as the green and sustainable development path of new urbanization construction, and the in-depth cooperation and alliances of building industry chain enterprises. According to industry insiders, the industrialization of construction can effectively promote in-depth cooperation and alliances among industry chain enterprises, helping enterprises open up new markets.

Steel structures offer numerous advantages over traditional concrete and masonry structures. They are stable, lightweight, high-strength, and boast excellent seismic performance. Fabrication can be done off-site in factories, leading to high-precision assembly, faster construction, and shorter project durations. They are also considered “green buildings,” with low initial costs, recyclable and reusable materials, and are energy, land, and water efficient. As an eco-friendly building material, steel-structured homes have been designated a key promotion project by the Ministry of Construction in recent years. However, this excellent building structure has one fatal flaw: poor fire resistance.

With the rapid advancement of urbanization, the burgeoning population in cities has created an urgent need for housing. Industrialized steel-structured housing will become the first choice. Authoritative departments predict that by 2015, steel-structured housing will account for 15%-20% of the total housing construction in the country. For nearly 20 years, the development and construction of steel-structured housing in China has been difficult, with low market penetration and annual construction volume less than 1%. In particular, the significant loss of life and property caused by the Tangshan, Wenchuan, and Yushu earthquakes has challenged China's housing construction system and structural safety performance. The excellent earthquake resistance and numerous advantages of steel-structured housing are evident.
