铝合金系留轨道装焊工艺应用

摘要

铝合金系留轨道材质和结构都比较特殊，自身结构为封闭箱形梁。系留轨道安装在主甲板上，截面结构板厚度变化大，焊接质量要求高。本文结合材质和现场施工状况，制定相应施工工艺，并对焊缝进行性能分析，以控制现场装焊质量，完成系留轨道装焊。%The material and structure of aluminum tethered track is unique and the structure is of a closed box beam. The tethered track is installed in main deck, there is a large variation of section structure and board thickness and the high quality of welding is required. In this paper, considering material and the condition of site construction, suitable welding technology is adopted and the performance of weld bead is analyzed to control the quality of site welding and to complete the fabrication of tethered track.
