Embodiment Construction
[0030] The present invention will be further described below in conjunction with drawings and embodiments.
[0031] A welding process suitable for large-section medium-thick plate box columns, comprising the following steps:
[0032] Step (1) The general principle to be followed in welding: the welding of the four outer box butt transverse joints of the upper and lower columns of the box-shaped column and the cross-shaped butt joint transverse joints in the cavity generally follow the internal and external, front and rear, left and right symmetry, and the same direction and the same specification The principle of welding.
[0033] Step (2) Welding sequence and section division:
[0034] A. If figure 1As shown, first divide the welding area into eight sections, which are ① section, ② section, ③ section, ④ section, ⑤ section, ⑥ section, ⑦ section and ⑧ section, and the welding sequence Section ①→section ②→section ③→section ④→section ⑤→section ⑥→section ⑦→section ⑧, where ①-⑥ ...
