摘　　要：在船舶营运过程中,往往需要去除焊缝表面涂层来保证磁粉或渗透检测的准确性,工序繁琐,检测效率低,且检测后重涂涂层的防锈蚀效果必然会受到影响。以20碳钢焊缝为试验对象,按照ASME标准要求设计加工人工缺陷,分别开展有无模拟涂层下的阵列涡流检测试验。试验结果表明,阵列涡流检测技术能满足船舶碳钢焊缝表面无损检测的要求,特别是在检测效率、信号显示等方面,阵列涡流检测技术具有明显的优势。It is often necessary to remove the weld surface coating to ensure the accuracy of detection during the operation of the ship, which is cumbersome and low detection efficiency. Moreover, the anti-corrosion effect of the recoating after detection is inevitably affected. This paper takes 20 carbon steel weld as the research object, designes and processes manual defects according to ASME standards, and carries out array eddy current detection tests with or without analogue coating. The experimental research has shown that array eddy current testing technology can meet the surface testing requirements of ship carbon steel weld, especially has obvious advantages in terms of testing efficiency and signal display.
