With the continuous changes in the demand of the construction industry, the steel structure has been widely used in plant buildings. The main components of the steel structure plant are welded H -shaped steel columns, beams, and support. These components have welding deformation during the production process. If welding deformation is not corrected, it will not only affect the overall installation of the structure, but also reduce the safety and reliability of the project. So what are the deformed correction methods of steel structure? And what kind of correction method is used in construction now, the SAFS steel structure is explained in detail for everyone.
The method of correction commonly used in the production process is mainly mechanical correction, flame correction and comprehensive correction. But flame correction is a difficult work. Methods and improper temperature control can also cause new larger deformation of components. Therefore, flame correction must have rich practical experience. This article gives a rough analysis of the types of steel structure welding deformation and correction method.
Types and flame correction of steel structure welding deformation:
The main components of the steel structure are welded H -shaped steel columns, beams, and support. Welding deformation often adopts the following three flame correction methods:
(1) Wire -like heating method;
(2) Point heating method;
(3) Triangular heating method.
The following introduces the construction method of different parts.
The following is the heating temperature when the flame correction is corrected (the material is low -carbon steel)
Low temperature correction (500 degrees ~ 600 degrees): cooling method: water
Medium temperature correction (600 degrees to 700 degrees): cooling method: air and water
High temperature correction (700 degrees to 800 degrees): cooling method: air
Explanation in the comprehensive article, you can generally understand the correction method of this steel structure material when deformation. In addition, the heating temperature should not be too high when the flame correction, which will cause metal to become brittle and affect impact toughness. 16mn does not cool water when corrected at high temperature, including steel with a large tendency of thickness or hardening. Hope that the introduction in the article is helpful to everyone.
