description: Theme of the final qualification work: "Technology of underwater wet welding of steels". The thesis describes the types of underwater welding. Their literary review is made. The method of underwater wet welding of steels is considered in more detail. The problems that arise during underwater welding are described. Information about defects and properties of welded joints is provided. The influence of depth (and with it an increase in hydrostatic pressure) and chemical composition on the quality of the welded joint. Welding materials and equipment used in underwater welding are considered. The safety requirements are given. Also, in this paper, the results of experiments of mechanized underwater wet welding are presented. As a welding material, cored wire was invented in the laboratory of the VSHFITM. The results of the experiments are of great importance for the study of phenomena and processes occurring during wet welding. In the future, this will contribute to the implementation of the semiautomatic wet welding process with the help of powder wire. The relevance lies in the great need for the transition to semiautomatic welding in the implementation of large volumes of welding. The importance of the project, the presence of scientific novelty and practical value allows us to positively evaluate the topic of the final qualifying work.
