Abstract
The influence of the parameters of feeding and heating of an additional flux-cored electrode during machine hidden arc welding with an additional hot additive on the process is considered. Beads are deposited onto a 10-mm-thick steel (St3sp steel, GOST 380) plate, and the addition conditions, namely, the distance between the flux-cored electrode and the filler wire and the filler wire feed rate, are varied. The filler wire feed rate is found to depend on the electric current used for heating and to be independent of the distance between the point of introduction of the additional hot additive and the main arc. The limiting amount of the filler wire additive at which the transition from a deposited metal to the base metal is not sharp is determined.
