[0002] At present, when welding H-beams, the plates used for H-beam welding are generally placed directly on the ground, and then welded. Unavoidably, such welding of H-beams will cause deformation, and the plates will be glued to each other. If the joint is not tight enough, large cracks will occur after welding, which will affect the quality of the welded H-beam

The invention discloses an H-type steel welding method. The welding method includes the following steps that (1)a firsts section, a middle section and a second section are sequentially placed on a first transverse section, a middle vertical section and a second transverse section of a welding device for H-type steel correspondingly; (2) welding is sequentially arranged at a first position, a fourth position, a second position and a third position; (3) the welding device is hoisted through a crane after the first position, the fourth position, the second position and the third position are cooled, and first middle positions of the first position and the second position are welded; (4) after the middle positions of the first position and the second position are cooled, third middle positions of the second position and the third position are welded; and (5) second middle positions of the first position and the second position are welded. By means of the welding method, the welding deformation degree can be reduced in the welding process; and in addition, cracks generated after welding can be reduced as many as possible, and the quality of the welded H-type steel is guaranteed.
Description
technical field [0001] The present invention relates to H-shaped steel, in particular, to a welding method for H-shaped steel. Background technique [0002] At present, when welding H-beams, the plates used for H-beam welding are generally placed directly on the ground, and then welded. Unavoidably, such welding of H-beams will cause deformation, and the plates will be glued to each other. If the joint is not tight enough, large cracks will occur after welding, which will affect the quality of the welded H-beam. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a welding method for H-shaped steel that can reduce welding deformation during welding and ensure the quality of the welded H-shaped steel. Contents of the invention [0004] The invention provides a welding method for H-shaped steel. The welding method can reduce the degree of welding deformation during the welding process, and can minimize the cracks after welding to ens...
