FIELD: machine building.
SUBSTANCE: proposed can be used in mechanised and automatic underwater welding and building up of metal parts. Flux cored wire for mechanised welding consists of steel shell and charge containing rutile concentrate, iron powder, nickel, alkali metal carbonate, alkaline metal complex fluoride, and additionally contains a core in form of ferromanganese, ferrosilicon, ferrotitanium and aluminium in following proportions, wt%: rutile concentrate 25-37; calcium fluoride 8-17; iron powder 32-45; nickel 1-3; alkali metal carbonate 3-7; alkaline metal complex fluoride 3-13; ferromanganese 4-6; ferrosilicon 2-4; ferrotitanium 1-3; aluminium 1-2.
EFFECT: proposed powder wire allows to improve quality of weld joint and increases impact strength of welds at underwater welding due to active metallurgic reactions on deoxidising welding bath.
