摘要
马鞍山长江公路大桥钢塔采用Q370qE和Q420qE钢,针对该钢塔使用的中厚板焊接,选择合理的焊接方法、焊接坡口、焊接材料以及焊接工艺参数进行焊接试验,通过焊接工艺评定试验及试验数据分析发现,各项性能均满足设计和相关标准要求。该焊接工艺成功应用于马鞍山长江公路大桥钢塔柱的制作,可供同类桥梁钢结构焊接制作借鉴。
Q370qE and Q420 qE steel were adopted for steel tower of Maanshan Yangtze River Highway Bridge.Reasonable welding process,welding groove,welding consumables and welding parameters were selected for medium thickness plate welding and welding test.The results of welding procedure qualification test and data analysis indicated that the properties could meet the requirements of relevant design standards.The selected welding procedure selected has been successfully used in the fabrication of steel tower columns of Maanshan Yangtze River Highway Bridge.This paper provided a reference for the welding fabrication of similar steel bridge projects.
