Embodiment Construction

[0015] Referring to the accompanying drawings, the welding process for anti-deformation of the end plate of the steel structure roof truss includes the following construction steps:

[0016] a. In the assembly process, when the upper and lower wing plates 1 and 2 open the breach 3, keep the direction of the groove consistent, and the angle of the groove is controlled at 30-40°;

[0017] b. In the welding process, the diameter of the welding wire is Φ1.2mm; the welding current is 280A; the welding voltage is 32V; the gas flow rate is 20ml / min. The specific construction sequence is as follows:

[0018] ① Weld the triangle plate of the upper wing plate 1 fully first;

[0019] ②The grooves of the upper and lower flanges should be primed. When the thickness of the flanges is >16mm, multi-layer and multi-pass welding methods should be adopted. After each welding, the welding slag spatter should be cleaned before the second welding can be welded to ensure penetration Welding require...

Abstract

The invention discloses an anti-deformation welding process for the end plate of a steel structure roof truss, which includes the following construction steps: a. In the assembly process, when the upper and lower wing plates 1 and 2 are opened with a breach 3, the direction of the groove is kept consistent , and the groove angle is controlled at 30-40°; b. In the welding process, the diameter of the welding wire is Φ1.2mm; the welding current is 280A; the welding voltage is 32V; the gas flow rate is 20ml / min. The invention solves the phenomenon that the end plates of roof truss beams and columns are prone to serious deformation after welding, achieves the purpose of effectively preventing severe deformation of the end plates, improves the overall structural strength of the steel roof truss, and saves construction cost and construction period at the same time.

Description

technical field [0001] The invention relates to the field of steel structure roof truss welding, in particular to a welding process for preventing deformation of end plates of steel structure roof trusses. Background technique [0002] For the field of steel structure production, welding is an important part of the construction part. The quality of welding seriously affects the bearing weight and service life of the steel structure. Because it is difficult to avoid welding deformation in the production and processing of various steel structure projects, resulting in After welding, a lot of manpower and material resources must be invested for correction, which has a huge impact on the entire construction period and production cost. Contents of the invention [0003] The purpose of the present invention is to provide a deformation-resistant welding process for the end plates of steel structure roof trusses, which solves the phenomenon that the end plates of roof truss beams ...
