Electroslag surfacing of 110G13L steel using various types of surfacing materials

ABSTRACT

Electroslag surfacing was performed in a $\text{empty}$180 mm current-conducting mould on 110G13L steel billets using shavings and electrodes from the same steel grade as a remelted material. It has been established that for any type of surfacing material, the structure of the deposited metal is austenitic. It is shown that the use of electroslag facing with chips allows to obtain a lower penetration of the base metal in comparison with electrode surfacing. The most dangerous area for the appearance of microcracks is the zone of fusion of the base and deposited metals, the width of which depends on the technology of surfacing and, accordingly, the power of thermal action on the base metal.
