摘要:
为了解决HFW管线钢管焊缝可靠性问题,通过使用高速摄像机实现了HFW焊接过程的动态可视化,并构建了一个HFW数值分析模型,从而优化HFW焊接条件并实现焊缝区域的均匀加热。试验结果表明,焊接条件优化后开发出的HFW钢管焊缝金属的夏比韧脆转变温度达到-90 ℃,且具有较高的低温吸收能量值。此外,开发的点融合串列束超声波检验方法实现了焊缝区氧化物的实时连续检测,其灵敏度为常规方法的10倍以上。
Abstract:
To address the significant need for weld seam reliability,the HFW phenomena were visualized dynamically using a high-speed video camera,and an HFW numerical analysis model was constructed to develop optimization technology of HFW conditions and the homogeneous heating technology of the weld zone. The Charpy fracture transition temperature of the weld metal of the developed steel pipe was -90 ℃ showing the high absorbed energy value at cryogenic temperature. Furthermore,real-time continuous detection technology of the oxide of the weld zone was developed by a point converging tandem beam ultrasonic inspection method. This technology achieved high sensitivity 10 times or more than that of the conventional method.
