摘要
在对X100高强度管线钢化学成分、力学性能分析的基础上,结合选定的焊接工艺方案,对该管线钢环焊缝焊接接头的强度、冲击韧性、硬度、断裂韧性(CTOD)和抗氢致开裂(HIC)等性能进行试验分析。结果表明,X100高强度管线用钢具有良好的焊接性能,焊接接头的各项性能指标均满足管道运行安全要求,所选用的焊接材料、焊接方法和工艺参数可用于该管材的现场焊接。
Based on the analysis of the chemical composition and mechanical properties,the tensile strength,low temperature impact toughness,hardness,CTOD and HIC of welded joints had been studied on X100 pipeline steel with the selected welding process,welding filler metal and technical parameter. The results show that the welding performance of X100 pipeline steel is good,and the welding process put forward in this paper can meet the working and application requirements.
