高层建筑钢结构在低温条件下的焊接施工

The Welding Work in Steel Frame Structures of High-rise Building at Low Temperature

焊接是高层建筑钢结构施工的关键技术之一,特别是在较低温度下焊接施工时,由于环境温度较低,加之高空风速较大,加大了施工难度。本文结合工程特点,通过工艺试验,制定了0℃以下高层钢结构焊接施工工艺,该工艺应用于实际工程,取得了满意效果。

Welding is one of the key technology for the construction of steel frame structure, especially when the works are at low temperature. Because of the very low temperature of the environment with very high wind speed in high altitude, the work is quite difficult. In this paper, considering the characteristics of the project, the welding process parameters in steel frame structures of high-rise building below 0℃ have been obtained by experiments. A satisfactory result in the application for the actual project has been obtained.
