description: The theme of the graduate qualification work: âDevelopment of welding technology of K70 pipes with the use of digital toolsâ. This research is devoted to increase of economic efficiency of large-diameter pipes production at IzhorÐ° Pipe Mill by means of development of welding technology for pipes of strength category K70 within the framework of the Power of Siberia - 2 project realization. The tasks that were solved during the study: 1. To analyze literature sources in order to determine the optimal welding technology, to identify weldability problems and ways to solve them; 2. Conducting pipe welding in order to test the hypotheses put forward and achieve the goals of the experiment; 3. Analyzing the results of the experiment; 4. Assessment of economic efficiency of product introduction into the production of IzhorÐ° Pipe Mill based on the Power of Siberia - 2 project. The work on experimental welding of pipes of strength category K70, diameter 1420, with wall thickness 26.26 mm was carried out based on the enterprise JSC Â«IzhorÐ° Pipe MillÂ», which is a part of PAO Â«SeverstalÂ» and is engaged in the production of large diameter pipes. Most of the research (non-destructive and destructive testing) was also carried out at IzhorÐ° Pipe Mill. Outside the enterprise, polygon tests of the customer PAO âGazpromâ were carried out. The result of the work is the development of welding technology for large-diameter pipes of strength category K70 and improvement of economic efficiency of Izhorsk Pipe Plant JSC.
