[0042] Example 1
[0043] In the box-shaped column thick plate welding process and welding deformation control method of the present invention, the box-shaped column is assembled and welded on the web and flange plate on the box-shaped component production line, and the welding of the four longitudinal fillet welds generally follows the left and right Symmetrical, simultaneous, same direction and same specification sequence; the length of the four longitudinal fillet welds of the box column is the requirement of full penetration, and the welding process first adopts CO 2 1-3 layers of gas shielded welding, and then submerged arc welding to fill the cover, including the following steps:
[0044] 1. The welding process of box-shaped column thick plate includes the following steps:
[0045] The steel structure of the Jiading Administrative Service Center project has a complex structure with a large number of thick plates, a large amount of weld metal filling, a large welding residual st...
