Abstract
Specific features of welding and surfacing by a flux cored wire of worn-out part surface are
considered in the paper. Specific features of metal melting and transfer during welding and
surfacing by a flux cored wire and the influence of the core composition, the mode of welding and
the structure of a flux cored wire are described. The efficiency of molten metal protection and
technological parameters of flux cored welding are determined by simultaneous melting of a metal
jacket and the powder core. Technological recommendations on the elimination of negative
phenomena in the process of flux cored wire welding are provided.
