东北地区钢结构工程冬季焊接施工质量控制

Welding Construction Quality Control of Steel Structure Engineering in Winter of Northeast China

钢结构的负温焊接技术历来是学术界、工程界共同关注的课题,结合在建哈尔滨大剧院的钢结构焊接工程,探讨了东北地区钢结构在冬季负温施工条件下的钢结构焊接预热保温工艺,以及防风技术措施和焊接人员、焊材、焊接机具的管理方法。

The negative temperature steel structure welding technology has always been issues of common concerned by academics and engineering. This paper discusses the steel welding preheat thermal technology,windproof technological measures and the management methods of welders,welding consumables and welding equipment under the construction conditions of negative temperature in the winter of Northeast China,which is combined with the steel structure welding engineering of Harbin Theater.
