Problems solved by technology

The existing cross-column steel member assembly and welding process is difficult for the welding of the cross-shaped weld in the center of the cross-column. The relationship between the plate thickness of the cross-column and the welding angle makes the welding efficiency low, the welding quality is difficult to guarantee, and the labor intensity of the workers is relatively high. Big

Embodiment Construction

[0014] Such as figure 1 , figure 2 , image 3 As shown, a cross column steel component assembly and welding process of the present invention includes the following steps: a, the first web lath 1, the second web lath 2, and the third web lath 3 are assembled into a cross shape, wherein The first web lath 1 and the third web lath 3 have the same width, and are half of the width of the second web lath 2, the first web lath 1, the second web lath 2, the second web lath After the three web strips 3 are set up, the cross-shaped weld seam welding groove can be formed; b, after the first web strip 1, the second web strip 2, and the third web strip 3 are assembled, the four A cross-shaped web is formed by welding the welding groove of the first welding seam. The welding groove of each welding seam is made by submerged arc welding, and then the reverse side is carbon planed to clean the root, and then the submerged arc welding is used to fill the cover surface. The cross-shaped weldi...

Abstract

The invention discloses a cross column steel member assembling and welding process. The cross column steel member assembling and welding process comprises the following steps: a, combining three web plate strips into a cross welding line welding groove, and the width of two of the web plate strips is identical and half of that of the other web plate strip; b, subjecting the cross welding line welding groove formed after combining the three web strips to welding to form a cross web plate; c, combining four flange plate strips with the cross web plate, and two welding line welding grooves are arranged between every flange plate strip and the cross web plate; and d, subjecting the two welding line welding grooves arranged between every flange plate strip and the cross web plate to welding to form a cross column member. According to the cross column steel member assembling and welding process, the problem that the central cross welding line in the cross column is difficult to weld due to a prolonged contact tube and welding on a fillet welding position can be solved, the production efficiency is improved, the welding quality can be guaranteed, and the labor intensity of workers can be reduced.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a process for assembling and welding cross column steel components. Background technique [0002] Steel structures are favored for their light weight, good seismic performance, good sense of space, and their unique environmental protection advantages. Therefore, more and more high-rise buildings use steel structures as their main structures, and cross columns are used in Quite common in high-rise buildings. The cross-column steel member has a cross-shaped web and four flange plates at the top of the web. At present, the assembly and welding process of the cross-column steel member includes the following steps: 1. Make an H-shaped steel and two T-shaped steels. The H-shaped steel consists of two Flange plate and a web lath, each T-shaped steel is composed of a flange plate and a web lath, the width of the web lath of the T-shaped steel is half of the width of the H-shaped steel ...
