description: The topic of the final qualifying work: "Research of welding technology and weldability of high-strength steels at low temperatures". In this paper, we consider the methods and technology of welding at low temperatures close to those of the Arctic. In particular, the welding of samples under reduced temperature conditions using carbon dioxide is considered. The main goals and objectives of the work. - analyze scientific sources of research on the weldability of steels at low temperatures; - to investigate the features of the assembly and welding technology at low temperatures; - conduct welding of prototypes at low temperatures; - to analyze the result obtained when checking prototypesÂ To analyze and study the welding technology and weldability of steels at low temperatures, international standards such as AWS, DNV GL and GOST were studied, conference materials on the topic of Arctic exploration were also studied.For the experiment, four plates were used to make two samples. Samples of plates according to geometric parameters were taken 150x40x3mm and with the help of carbon dioxide were cooled to a temperature of -48Â°C in a thermal container and a weld was made using mechanized wire welding in a carbon dioxide environment. After welding, the samples were carefully examined for defects formed during welding at low temperatures. Based on the results, a conclusion was made about the welding process and the weldability of the metal in conditions of low temperatures.
