- Abstract
Carried are the investigations on development of low-carbon chromium electrodes of 05Kh6MF type. Effect of coating composition on carbon content in deposited metal of Kh6M type was investigated. It is determined that joint introduction of chromium and zirconium oxides in 5-10 wt.% amount at simultaneous removal of marble from the coating is the most efficient for carbon reduction. Slag system of fluoride-magnesium oxide type coating was developed, providing reduction of carbon content in the deposited metal to 0.04- 0.06 wt.% at sufficiently low content of diffusible hydrogen. Electrodes of ANL-10 grade for welding of dissimilar joints of chromium martensitic steels of 10Kh9NMFB type and chromium-nickel austenitic steels of 10Kh18N10T type were developed on its basis. The electrodes provide for stable arcing, insignificant spattering, good weld formation in all spatial positions and easy separation of slag crust. 12 Ref., 3 Tables, 2 Figures.
