摘要:
针对某海上风电导管架吸力桶管径大、筒壁厚且立式建造导致的焊接工作量较大的问题,采用埋弧自动横焊焊接工艺,通过坡口设计、焊接工艺参数的合理选择,克服了横焊埋弧焊焊接过程中铁水下垂、层间未熔合、焊剂敷洒等操作难点,实现了埋弧横焊在吸力桶环缝的应用。风电导管架吸力桶埋弧自动横焊的焊接工艺试验结果显示,焊缝外观、硬度、力学性能均符合相关标准要求。该工艺的应用表明,吸力桶环缝焊接作业效率得到大幅提升,并且节约了人工成本。
Abstract:
In view of the large diameter,thick wall and large welding workload caused by the vertical construction of the suction bucket of a certain offshore wind pipe rack,the submerged arc automatic horizontal welding process is adopted. Through the groove design and the reasonable selection of welding process parameters,the operation difficulties such as water sagging, interlayer incomplete fusion and flux spraying in the horizontal submerged arc welding process are overcome, and the application of submerged arc horizontal welding in the girth seam of the suction bucket is realized. The welding process test results of the submerged arc automatic horizontal welding of the suction bucket of wind pipe rack show that the appearance,hardness and mechanical properties of the weld meet the requirements of relevant standards. The application of this process shows that the efficiency of girth seam welding of suction bucket is greatly improved and the labor cost is saved.
