摘　　要：对水下湿法药芯焊丝焊接的研究成果与发展现状进行了详尽的综述,介绍了水下湿法药芯焊丝焊接的优点、药芯成分的设计、工艺特点和接头性能,并提出了目前水下湿法药芯焊丝焊接存在的问题及今后的发展方向。水下湿法药芯焊丝焊接时,高氢含量、高压力和较快的冷却速度影响焊接接头的质量,而通过调整药芯焊丝的材料成分配比和在药芯中添加合金元素,可以实现渣气联合保护,达到优化焊缝组织性能的目的,也可以通过调整焊接工艺参数来优化焊缝。水下湿法药芯焊丝焊接技术的出现,使得水下焊接向高效、自动化的方向发展。The development of underwater wet flux- cored arc welding was reviewed.The advantages of underwater wet flux- cored arc welding,design of flux- cored component,welding process and the properties of joint were introduced.Furthermore,the problem of underwater wet flux- cored arc welding and the development direction were proposed.During the underwater wet flux- cored arc welding,high hydrogen content,high pressure and a faster cooling rate have influence on the welding quality.By adjusting the ratio of the material composition of flux-cored wire and cored in the alloying elements,slag-gas joint shielding effect can be achieved,which can be used to optimize the weld properties.Furthermore,the weld can be optimized by adjusting the welding parameters.Underwater wet flux- cored welding technology makes the underwater welding to efficient and automatic direction.
