Abstract
Technological parameters and welding productivity in case of application of the wire of three types were determined on the basis of experimental investigations of the welding technique of typical joints of the metallurgical complex units using self-shielded flux-cored wire. Advisability of using the double-layer wire in welding of the metal of medium and high thickness in downhand and horizontal positions of the welds is shown. It is expedient to use tubular wire of small diameter in fulfillment of welds in vertical and overhead positions. Technology for welding of typical metal structures was developed.
Keywords: arc welding, repair of metal structures, low-alloy steel, metallurgical complex, flux-cored wire, development of composition
