Abstract
Способ механизированной сварки плавящимся электродом в среде защитных газов с введением наноструктурированных порошков в зону сварки и формированием сварного шва, отличающийся тем, что защитный газ, проходящий через ниппель и осевой канал инжектора, попадает в смесительную камеру, создает разряжение в канале между смесительной камерой и накопителем, приводящее к подсасыванию наноструктурированных порошков из накопителя, наноструктурированные порошки через защитный газ проходят дуговой промежуток, и, попадая в сварочную ванну, служат дополнительными центрами кристаллизации при образовании зерна микроструктуры сварного шва, а увеличение количества центров кристаллизации в жидкой сварочной ванне приводит к образованию мелкодисперсной, однородной микроструктуры сварного соединения.Method of mechanized welding with a consumable electrode in a shielding gas environment with the introduction of nanostructured powders into the weld zone and the formation of a weld, characterized in that the shielding gas passing through the nipple and the axial channel of the injector enters the mixing chamber, creates a vacuum in the channel between the mixing chamber and the storage ring , leading to the suction of nanostructured powders from the storage ring, nanostructured powders pass through the shielding gas through the arc gap and, entering the weld pool, serve additional centers of crystallization during formation of grains of the microstructure of the weld and increasing the number of nucleation in the liquid molten pool results in a fine, uniform microstructure weld.
