钢桁梁关键焊缝焊接质量管理与控制

Steel Truss Key Seam Welding Quality Control

本文以清水河特大桥主桥钢桁梁主桁架上弦杆(含销接耳板节点板)关键焊缝的工艺设计与施工过程为例,介绍监理在钢桁梁主桁架上弦杆(含销接耳板节点板)关键焊缝工艺设计与焊接施工过程中如何有效进行监督与管理,针对存在的问题要求施工单位进行分析和改进。

By taking the Qingshuihe river Grand Bridge as an example, this paper introduces the effective work of plant engineering consultants in supervising the technological design and welding process of the key seam on the primary truss girder upper chord of the main bridge （pin saddle ear plate joint included）, Upon the demand of the consulting engineers, the contractor made relevant analysis and improvement in terms of the found problems.
