| 摘 要： | 相对于船舶和普通海洋钢结构,深水和大型海洋工程结构面临的安全性更为重要.焊接结构很容易出现断裂问题,其中多数为疲劳失效,对于这个问题除了通过优化设计和提高质量要求之外,通过制造工艺对焊接接头疲劳强度进行改善也是很好的选择.在此结合部分海洋工程建造规范和应用实践,介绍了包括焊缝外观整体加工、焊趾打磨、TIG熔修和锤击等在...

| Abstract: | The safety of deepwater or large offshore structures is distinctly important than ship and other ordinary marine structures.Welded steel structures have high crack risk,especially fatigue cracks.In some cases,except good design and additional quality requirements,it is a good solution that uses manufacturing process to improve weld detail fatigue strength.Based on some offshore codes and engineering practice,this paper introduce some usual weld detail fatigue strength improvement methods,including weld prof... |
