The effect of parameters of flux-cored strip surfacing modes on geometric dimensions of deposited beads was investigated. The peculiarities of flux-cored strips melting were considered depending on a sheath type and chemical composition of the core. As the objects of investigations the widely applied flux-cored strips PL-AN 101 and PL-AN 179 were selected, which are manufactured on a base of the steel strip-sheath and also the strip PL-AN 111 based on a nickel sheath. The surfacing was carried out in the machine A-874N, equipped with the power source VDU 1201 and the attachment AD 167 within a wide range of modes. It was found that with increase in current from 600 to 1200 A for all the tested grades of flux-cored strips, the growth of a bead width, its height and penetration depth of base metal are characteristic. With increase in current the value of weld shape factor for all the considered types of flux-cored strips decreases. With increase in the arc voltage in the range of 24–38 V the bead width increases and the height is reduced against the growth in volume of base metal. The change in penetration depth and the weld shape factor are ambiguous and depend on the flux-cored strip type. 10 Ref., 1 Table, 4 Figures.
