水下湿式焊接是最经济的水下修理方法。如果仔细选用设计焊条及焊接工艺,可以提高湿式焊缝质量而扩大其应用范围.鉴于1983年公布的水下焊接标准 AWS D3.6(美国)已为国外近海工业界采纳,作为水下焊接质量要求及焊接工艺合格考核的依据,建议我国近期在水下焊接方面的试验研究和水下焊工的培训,参照这个标准.水下焊条是湿式焊接成功的关键,本文介绍了最近国外开发研究的水下焊条情况。最后列举了国外近海设施采用湿式修理的一些实例.
Underwater wet welding is the most economical method of underwater repair. If carefully selected design welding rod and welding process, can improve the quality of wet welds and expand its scope of application.While in 1983 published underwater welding standard AWS D3.6 (United States) has been adopted for foreign offshore industry, as underwater welding quality Requirements and qualification test of welding technology, it is suggested that China’s recent underwater welding research and underwater welder training, with reference to this standard.Water underwater welding is the key to the success of wet welding.This paper introduces the recent research and development of water Under the welding conditions. Finally, some examples of adopting wet repairs by foreign offshore facilities are listed.
