A method of coarse-grained submerged hard-facing by a strip electrode, at which the strip electrode is bent and by means of driving rollers, rotating at constant speed, and a feed device is fed into the area of hard-facing. The strip electrode before feed into the fusion area is bent at an angle of 110-120° relative to the axis perpendicular to the vertical axis of feed of the strip electrode. The feed of the end of tape electrode into the area of hard-facing is performed by pulse motions. |
