Zusammenfassung:The invention belongs to the technical field of steel structure buildings, and particularly relates to a manufacturing process of welding I-shaped steel for a steel structure. The manufacturing process is characterized by comprising the following steps: (1) blanking of an upper flange plate, a lower flange plate and a web plate; (2) forming and correcting of the upper flange plate or the lower flange plate; (3) web plate forming; (4) assembly of the upper flange plate, the lower flange plate and the web plate; (5) welding of the upper flange plate, the lower flange plate and the web plate; (6)correcting; and (7) relief of internal stress. The steel-structure welded I-shaped steel flange plates with the inclined surfaces manufactured with the manufacturing process not only reserve the excellent section characteristics of the traditional I-shaped steel, but also overcome the defect that the traditional I-shaped steel cannot be used for processing a section material for a large-section structure. 本发明属于钢结构建筑的技术领域
