Embodiment Construction

[0014] see figure 1 , 2 shown.

[0015] Cut the H-shaped steel web (2) to be cut along the center line by 500mm to form the cut area (4), keep the connection at 100mm to form the connection area (3), cut it at 500mm, and connect at 100mm. In such a cycle, the processed web (2) and the two flange plates (1) are tailor-welded to form an H-shaped steel, and then welded by submerged arc welding, then assembled and formed, and finally the 100mm connection area (3) is cut off In this way, the cut H-shaped steel becomes two symmetrical T-shaped steels, and the heating area is greatly reduced, so that the verticality, twist and straightness can be effectively guaranteed. The assembled cross column fully meets the design requirements, the welding current of the cross column must not exceed 300A, the voltage is 35-38V, and the welding sequence is diagonal, circular, and alternate.

Abstract

The invention relates to a method for anti-deformation of steel plate tailor welding cross columns. The edge plates are assembled into H-shaped steel by tailor welding, and then submerged arc welding is carried out, and then assembled and formed, and finally the connection points of the remaining connection parts are cut off. The invention provides a cross column that can prevent the deformation of the tailor-welded cross column, and can accurately correspond to the connecting hole of the beam, so that the installation is smoother.

Description

technical field [0001] The invention relates to a welding method for special-shaped steel plates, in particular to a welding method for preventing welding deformation of special-shaped steel plates. Background technique [0002] The steel structure cross column is an important structural column in the frame, and its quality directly affects the accuracy of the upper and lower columns and the connection holes between the cross column and the beam when the steel structure is installed on site; It is difficult to accurately grasp the size of the tailor-welded, which makes it difficult to correspond to the connecting hole group between the cross-column and the beam produced by tailor-welding, and the size error is large, which increases the difficulty of on-site installation. [0003] Contents of the invention [0004] The invention aims at the deficiency of the existing cross-column welding method, and provides a welding anti-deformation method which can prevent the deformat...
