转换柱的焊接

Welding of transformation column

某超高层钢结构的下部采用十字型断面的柱子,而中部和上部却采用箱型断面的柱子,于是出现了从十字柱向箱型柱过渡的转换柱。转换柱的焊接难度很大。详细介绍了通过控制母材质量、焊材质量、焊前准备、焊接参数等,完成转换柱的焊接。经检测,焊缝质量和结构的形状、尺寸满足要求,已交付安装。

Cross-type profile column are used in the bottom of steel structure in some ultrahigh laver.but box-type profile columns in the middle and upper part ,so the eolumns which transforms from cross-type to box-type are needed.It＇s very difficult to weld transformation column.This paper introduces the welding of transformation column by controlling the quality of master materials and welding materials ,welding preparation ,welding parameters and so on.By inspection, the seam＇s quality ,structure and shape meet the demand, and the transformation column are in use.
