What are the precautions to be taken in the manufacturing of steel structures

At present, steel structure manufacturing has been widely used in factory buildings. The main components of the steel structure factory building are welded H-shaped steel columns, beams, and braces. These components all have welding deformation issues during the manufacturing process. If welding deformation is not corrected, it not only affects the overall installation of the structure, but also reduces the stability of the project

The commonly used correction methods in the production process mainly include mechanical correction, flame correction, and comprehensive correction. However, flame correction is a difficult task to operate, and improper control of methods and temperature can also cause new and significant deformation of components. Therefore, flame correction requires rich practical experience. The stress caused by flame correction is the same as the internal stress in welding. Inappropriate correction can result in the superposition of internal stress, welding internal stress, and load stress, which can cause the longitudinal stress of columns, beams, and braces to exceed the allowable stress, leading to a decrease in the bearing capacity. Therefore, caution should be taken in the manufacturing of steel structures, and reasonable process measures should be adopted as much as possible to reduce deformation. Mechanical correction should be used as much as possible during correction
