The paper gives the results of investigation of effect of composition and thermophysical properties of weld pool molten metal on penetration efficiency in submerged arc surfacing using strip electrode. The results of processing and analysis of received experimental and calculation data show that under conditions of formation of composition of weld pool close to strip electrode composition, reduction of penetration area is correlated with reduction of melt enthalpy at replacement of Sv-08kp strip by Sv-12Kh18N10. 8 Ref., 1 Table, 4 Figures.
