Embodiment Construction

[0034] The following is attached Figure 1-2 The application is described in further detail.

[0035]The embodiment of the present application discloses a kind of H-shaped steel, referring to figure 1 , an H-shaped steel includes an upper wing 1 , a lower wing 2 and a web 3 . The length directions of the upper wing plate 1, the lower wing plate 2 and the web 3 are consistent, and the upper wing plate 1 is welded and fixed on the upper end surface of the web plate 3, and the lower wing plate 2 is welded and fixed on the lower end surface of the web plate 3.

[0036] refer to figure 1 A slot 11 is opened on the opposite side of the upper wing plate 1 and the lower wing plate 2 , and a positioning groove 12 is opened at the bottom of the slot 11 . The groove width of the positioning groove 12 is greater than the groove width of the slot 11 . Both sides of the web 3 are plugged into the slots 11 , and both sides of the web 3 are fixed with fixing bars 31 , and the fixing bars ...

Abstract

The invention relates to an H-shaped steel welding process, and relates to the field of steel welding processes. The H-shaped steel welding process comprises the following steps that blanking is conducted; pre-assembling is conducted, specifically, guiding pieces are welded to the opposite sides of an upper wing plate and a lower wing plate; the H-shaped steel is assembled, specifically, the upperwing plate and a web plate and the lower wing plate and the web plate are guided and assembled through the guiding pieces; positioning welding is conducted, specifically, the ends of the assembled H-shaped steel are subjected to spot welding, then the joint between the upper wing plate and the web plate and the joint between the lower wing plate and the web plate are welded, finally, the guidingpiece located on the upper wing plate and one side of the web plate are welded and fixed, and the guiding piece located on the lower wing plate and the other side of the web plate are welded and fixed; straightening is conducted, specifically, the welded H-shaped steel is straightened; and inspection is conducted, specifically, the welding precision and the bending resistance of the finished product are inspected. The welding process has the effect of improving the welding precision among the upper wing plate, the lower wing plate and the web plate during welding.

Description

technical field [0001] The present application relates to the field of steel welding technology, in particular to an H-shaped steel welding technology. Background technique [0002] H-shaped steel is an economical cross-section high-efficiency profile with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used. [0003] The existing Chinese invention patent with the notification number CN102059524A discloses a manufacturing process of a solid-belly welded H-shaped steel plate, which mainly includes the following steps: 1) blanking of the panel; 2) assembly of the I-type; 3) automatic submerged arc Welding; 4) Straighteni...
