[0002] In shipbuilding or steel structure engineering, T-beam structures are more common. In the conventional T-beam manufacturing process, certain angular deformations will occur after welding of the panels and webs, and these deformations basically exceed the tolerance requirements and do not meet the requirements. Subsequent assembly accuracy requirements, but to correct this kind of angular deformation requires a lot of pyrotechnic work, which takes a long time and requires a lot of human resources
Because such components are widely used in ship structures, with the accumulation of time, this will cause a lot of cost waste

Abstract
The invention discloses a making method of a T-shaped beam. Before assembly, a detection sample plate is made according to the calculated inclination amount at first, wherein the inclination amount isthe to-be-released offset amount of angular distortion in the assembly process; in the assembly process of a face plate and a web, the detection sample plate is utilized for detecting whether or notthe inclination amount is added or released properly, after detection and correction are conducted, firstly, welding is conducted at the side with the inclination direction opposite to that of the web, then welding correction is conducted at the other side, then removal of the inclination amount is facilitated, and therefore, after welding is completed, the perpendicularity between the face plateand the web meets the requirement; implementation of distortion correction by flame is omitted, thus the time for flame work is saved, the production period is shortened, and the construction difficulty is reduced. The making method is used for the field of ship building engineering.
Description
technical field [0001] The invention relates to the field of shipbuilding engineering, in particular to a method for manufacturing a T-shaped beam. Background technique [0002] In shipbuilding or steel structure engineering, T-beam structures are more common. In the conventional T-beam manufacturing process, certain angular deformations will occur after welding of the panels and webs, and these deformations basically exceed the tolerance requirements and do not meet the requirements. Subsequent assembly accuracy is required, but to correct this kind of angular deformation requires a lot of pyrotechnic work, which takes a long time and requires a lot of human resources. Since such components are widely used in ship structures, with the accumulation of time, this will cause a lot of cost waste. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing a T-shaped beam that meets the verticality requirement after welding....
