The steel structure of plamsholding dagoba for Famen Temple is constructed with steel Q345GTC. The construction period is necessity through the winter, even from ovember of 2007 to February of 2008. Negative temperature of environment exerts direct influence to welding quality. If the droping speed of temperature is quick, the metal will be brittle, also, the possibility of crack produced at weld is increased.

摘要］ 法门寺合十舍利塔钢骨结构工程钢骨采用Q345GJC钢，施工经过冬季阶段（2007年11月～2008年2月），由于冬季施工的负温环境会使焊接质量受到直接影响，降温速度加快使焊缝金属脆化，增加裂纹产生的可能性，控制不好会造成焊接质量的下降甚至造成安全隐患。

According to the chemical metallurgy principle of self-shielded weld and the analysis on the deoxidization and nitrogen fixation of the metal such as aluminium, titanium,and etc.
