Abstract

The invention discloses a method for controlling angular deformation of horizontal flanges, and belongs to the technical field of welding machine shells. The method for controlling angular deformationof the horizontal flanges includes the following steps that two sealing bodies are put between the opposite ends of the two horizontal flanges, and the two sealing bodies and the two horizontal flanges are connected and fixed through two bridging tie bars; the sealing bodies and the horizontal flanges are welded, and the bridging tie bars are removed; end plates on the two sides and an outer shell plate in the middle are spliced on the two horizontal flanges and the two sealing bodies and welded, and a welded shell is obtained; and the welded shell is subjected to stress elimination. By meansof the method for controlling angular deformation of the horizontal flanges, the overall rigidity of the horizontal flanges can be improved, and the risk of deformation generated by the horizontal flanges after stress is eliminated is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of welding casings, in particular to a method for controlling the angular deformation of a horizontal flange. Background technique [0002] The welding casing of MCL centrifugal compressor includes two forms of upper and lower casings in structure. The welding casing (upper and lower) is composed of horizontal flange components, end plates, outer shell plates, support rings, inner shell plates and various The internal deflector and spiral plate of the chamber are assembled and welded. [0003] For the horizontal flange assembly weldment, according to the technical requirements of the design drawing and the mature production application in the past, the horizontal flange assembly weldment must be put into the furnace for stress relief treatment after the overall welding is completed. [0004] However, after the stress relief treatment, the re-inspection of the weldment of the horizontal flange assembly on th...
