Influence of electrode wire feed rate 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 rate regulation 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 rates, there exists such an optimum ratio of feed rate and other surfacing parameters for each wire diameter, at which increase of this rate leads to reduction of penetration depth and share of base metal in the deposited metal at rising surfacing current. 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 Tabl., 5 Fig.
