Abstract

The results of corrosion tests of austenitic-martensitic steel deposited on 40X steel samp­les under a layer of АN-26 flux-cored wire Pd-Np-30Kh22МN with a diameter of 2.2 mm in one layer with 50% overlapping rollers under two modes of its supply to the welding bath (0.5 and 0.7 Hz) are presented. It is established that the best operational characteris­tics under the influence of the corrosive environment are obtained during surfacing with a pulse of an electrode wire supply of 0.7 Hz.
