Abstract
The paper studies the peculiarities of application of flux-cored wires for welding of metal structures of low-alloy steels of increased and high strength. The ways have been proposed for solving the problems existing in this field. The flux-cored wires developed in the recent years at the E.O. Paton Electric Welding Institute for these purposes were described. The directions of increase of quality and efficiency of flux-cored wire welding using modern equipment have been presented. 15 Ref., 2 Tables, 7 Figures.
Keywords: electric arc welding, flux-cored wire, low-alloy high-strength steels, heat input, wire melting efficiency, automation and control of welding process
