Claims (1)

Способ электродуговой сварки погруженной дугой неплавящимся электродом, включающий формирование нескольких кольцевых потоков защитных газов, охватывающих дугу и сварочную ванну, отличающийся тем, что подача дугоплазмообразующего, стабилизирующего и защитного газа осуществляется одновременно тремя отдельными струйными потоками, каждому из которых придают вращательное движение, они движутся вокруг оси электрода по спирали в одном направлении, но с разными углами закручивания и скоростями истечения газа, с увеличением от внутреннего к внешнему, причем внешний поток дополнительно направляется защитным соплом вокруг сварочной ванны, а отключение потоков производится в следующей последовательности: сначала дугоплазмообразующий и стабилизирующий поток, затем внешний защитный поток.A method of electric arc welding with a non-consumable electrode by immersed arc, including the formation of several circular flows of protective gases, covering the arc and the weld pool, characterized in that the arc-plasma forming, stabilizing and protective gas are supplied simultaneously by three separate jet streams, each of which is given a rotational movement, they move around the axis of the electrode in a spiral in one direction, but with different twisting angles and gas flow rates, with an increase from the internal to the external, and the external stream is additionally directed by a protective nozzle around the weld pool, and the flows are switched off in the following sequence: first, an arc-plasma forming and stabilizing stream, then an external protective stream.
