摘要:
焊缝余高过高,焊缝与母材过渡角过小会引起焊趾处应力集中,导致服役条件下管道疲劳破坏,影响管道的安全运行,加大钢管的外防腐作业难度,造成焊缝部位防腐层厚度的减薄甚至开裂。针对这些问题,分析了影响焊缝余高质量的主要因素,以及改善焊缝形貌所采取的工艺措施,如坡口和焊接工艺参数的优化设计、焊丝形位参数的调整。焊缝形貌的改善在实际生产中取得了满意的效果。
Abstract:
Over height weld reinforcement and too small transition angle between weld and base metal will case stress concentration in weld toe, which can lead to fatigue rupture to the pipeline under service condition, and even influence pipeline safety operation, add much more tasks difficulty of steel pipe external coating, and cause weld external coating thickness reduction even to cracking. Aim at these problems, it analyzed the major factors affecting weld reinforcement quality, and the process measures to improve weld profile, such as optimizing design for bevel and welding process parameters and adjustment for the angle and location of welding wire. By implementation of the above measures,it improved the weld profile and obtained satisfactory results in practice production.
