Claims (1)

Способ наплавки ответственных деталей из высокоуглеродистых сталей, включающий наплавку двумя проволочными электродами под слоем флюса, отличающийся тем, что производят предварительный нагрев наплавляемого изделия в пределах 240-260oС, а наплавку производят в разные сварочные ванны от двух независимых источников постоянного сварочного тока, причем последним накладывают отжигающий валик одной и второй дугой, шлак с которого не снимают, а деталь после наплавки медленно охлаждают со скоростью не превышающей 5oС в мин.A method for surfacing critical parts from high-carbon steels, including surfacing with two wire electrodes under a flux layer, characterized in that the deposited product is preheated in the range of 240-260 o C, and surfacing is performed in different weld pools from two independent sources of constant welding current, and the last is applied an annealing roller with one and the second arc, from which the slag is not removed, and the part is slowly cooled after surfacing at a speed not exceeding 5 o C per min.
