Common problems in the quality inspection of steel structure processing and welding
Yunnan Steel Structure Manufacturers Discussion of Common Problems in the Quality Inspection of Yunnan Steel Structure Processing and Welding
During the welding process of steel structures, due to many factors, some quality problems will occur in the welding of steel structures. Therefore, some problems will occur during the welding process, such as bubbles, slag inclusion, weld bead, undercut, cracks, etc. These problems and serious post-weld deformation are common problems that easily occur during welding.
After the steel structure is deformed, its shape changes, and its stress points also change accordingly, which will affect the load-bearing capacity and assembly quality of the Yunnan steel structure. Especially after the steel structure is stressed and deformed, it is not easy to restore its shape. Even if there are some methods to restore it, it will cost a lot of manpower and material resources; otherwise, it will have to be scrapped.
Imperfect welding management and design can also lead to serious problems. Unreasonable design and construction requirements of welding points can lead to serious problems during welding. This kind of fracture often occurs during steel structure installation. The main reason is that during the steel structure processing and welding, due to factors such as welding speed and current, the welding point is heated unevenly. Coarse grains will reduce the toughness of this area, easily leading to sudden fracture of the steel structure during installation. However, this situation may cause great harm to our construction personnel, so it is necessary to try to prevent this situation during welding.
Due to the unskilled professional skills of welders, many welding bumps will occur. Therefore, it is necessary to improve the operating strength of our workers and practice more to avoid such problems. Through the quality inspection of Yunnan steel structure processing and welding, these problems can be avoided as much as possible, and the safety of construction personnel and users can be better guaranteed. Therefore, it is very necessary to check the quality of Yunnan steel structure processing and welding.
