Abstract:

With the rapid development of marine engineering, the research and application of underwater welding technology has become the key to marine engineering construction. In this review, the classification and characteristics of underwater welding were briefly described. The influence of underwater environment, welding materials, and welding process on the quality of underwater wet welding was analyzed. The application of in-situ observation method and external auxiliary means in the field of underwater wet welding was introduced. The research results of underwater local dry-laser welding with powder feeding/wire feeding were summarized. The research progress of underwater dry method under different water depths was introduced. The research results in the field of underwater friction-stir welding were analyzed.
