Pulse-Arc Surfacing of Corrosion-Resistant Austenitic-Martensitic Steel

We present the results of corrosion testing of austenitic-martensitic steel deposited on 40Kh steel samples under a layer of AN-26 flux with the help of a Pd-Np-30Kh22MN flux-cored wire with a diameter of 2.2 mm in a single layer with 50% overlapping of the rollers for two modes of delivery into the welding bath (0.5 and 0.7 Hz). It is found that the best operating characteristics under the influence of corrosive media are attained as a result of surfacing with pulses of electrode wire supply of 0.7 Hz.
