It is recommended to use the tested and certified method of automatic argon-arc welding with 0.8-0.9 mm filler wire, instead of manual welding, to produce sound joints between elements of the main circulation piping and steam generator branch pipes. The suggested process allows reduction in labour consumption and welding operation cycle, provides high and consistent quality of welded joints, and makes it possible to decrease dose of the radiation effect on personnel performing welding operations.
