Abstract

The invention discloses a method for controlling tower foot welding deformation and hot-dip galvanizing stress relief deformation. The method comprises the following steps that S1, a locating plate with a thickness of 10 mm and a locating plate with a thickness of 20 mm are adopted; S2, the assembly positions of two pieces of angle steel are adjusted through a mold, spot welding is carried out after it is confirmed that the assembly positions of the angle steel are qualified, and the rest of installing and welding plates are installed and welded in sequence according to the preset size; S3, after installing and welding in S2 are completed, the locating plate of 10 mm is embedded into the position 90-110 mm away from holes in the lowest ends of the two pieces of angle steel, and welded to the two pieces of angle steel; S4, the locating plate of 20 mm is placed at the top ends of the two pieces of angle steel, and spot welding is carried out; and S5, vertical plates are arranged in and on the two pieces of angle steel, and the angle steel and the vertical plates are sequentially welded on a flange bottom disc. According to the method, the problems that welding deformation and hot-dip galvanizing stress relief deformation are prone to happening to a tower foot of a double-back main material iron tower in the production process, and consequently after deformation happens, the iron tower is hard to mount, the structural bearing capacity is low, and operating stability is poor are solved.

Description

technical field [0001] The invention relates to the technical field of production of double-back main material iron tower feet, in particular to a method for welding deformation of the tower foot and hot-dip galvanizing stress release deformation. Background technique [0002] In order to improve the quality of welded products, the reasons for the difficulty in the installation of the iron tower due to welding deformation and hot-dip galvanizing stress release deformation were analyzed for the main material of the double-back iron tower. The following problems were found: Although the common methods of controlling welding deformation such as: However, after the welding is completed, the steel support is removed after natural cooling at room temperature, and hot-dip galvanizing is carried out after pickling and rust removal. Since it needs to be dipped in a zinc solution at about 450°C The welding stress carried out in about 15 minutes was released irregularly, which resulted...
