Influence of electrode wire feed speed on base metal penetration and geometrical dimensions of deposited beads at submerged-arc surfacing was studied. Four flux-cored wires of 1.2; 1.6; 1.8 and 2.0 mm diameter were used in the experiments. Feed speed adjustment was performed in the range from minimum value Vf.min, at which a stable surfacing process can be in place for these conditions, and up to maximum value Vf max = 450 m/h, which was determined by the characteristics of the used surfacing unit. It is found that at surfacing with high wire feed speeds, there exists such an optimum ratio of feed speed and other surfacing parameters for each wire diameter, at which increase of this speed leads to reduction in penetration depth and share of base metal in the deposited metal at rising current of surfacing. Results, obtained in this work, were successfully applied at wear-resistant arc surfacing of 3 mm steel sheets, and can also be used in selection of modes of arc surfacing of other parts, which to the greatest extent meet their operating conditions, and requirements to deposited metal and base metal penetration. 10 Ref., 4 Tables, 5 Figures.
