The paper deals with the effect of dispersed particles of refractory compounds (Al2O3, MgO, ZrO2) added as cold filler to 1.6 mm flux-cored wire, on modification of the dendrite structure in low-alloy weld metal of C–Mn–Cr–Ni–Mo–Si–Cu system of K65 strength class. Obtained results allow expanding a data base on the mechanism of the effect of refractory oxides on dendrite structure modification. 5 Ref., 6 Tables, 14 Figures.
Keywords: arc welding, low-alloy steel, weld metal, modification by refractory oxides, dendrite structure, mechanical properties
