摘　　要：为了解决海洋采油平台在使用过程中出现的材料老化及结构受损等问题,开发了适用于海洋工程结构物维修的水下湿法焊接工艺,本研究采用Broco水下焊条在试验水槽内进行了初步的水下焊接工艺研究,并在焊后对接头进行无损检测、力学性能测试和金相分析等试验。试验结果表明,焊接接头的各项性能指标均满足美国水下焊接AWS D3.6:2010标准B级焊缝的要求,为后续开发更大水深的湿法焊接工艺积累了经验。In order to solve the problems of the material aging and structure damage during the service of offshore engineering structure,it is necessary to develop underwater wet welding procedure.Under this background,a preliminary underwater wet welding procedure research is performed in a test water channel with the Broco electrode, and a series of test results is finished such as the NDT test, mechanical property test and microstructure analysis after welding.The results show that the performance of tested weld joints meets the B level requirements of AWS D 3.6：2010 and the research work accumulates a lot of experience and data for further underwater welding procedure for development of deeper water.
