ABSTRACT OF THE DISCLOSURE Equipment for the electroslag surfacing of rolls. A roll to be surfaced is held in vertical position. One or more vertical supports are provided of which a first platform or lower carriage carrying a rotatable sleeve with an annular crystallizer surrounding the roll is located to permit vertical travel thereof, and an upper platform or upper carriage, carrying a swivel plate with bus bars for supplying generally vertically disposed welding electrodes with welding currents equipped with rollers on the bottom resting on a circular guiding path is provided, each electrode having a fixing mechanism with a support. A rotary mechanism for the guidance of welding electrodes into the weld gap is mounted on one or more upper sleeves, and is insulated from the crystallizer, while the bus bars are divided into three segments insulated from each other, each bus bar being connected with its respective phase of a three-phase current supply. A fixing mechanism and supports are placed on the inner perimeter of the swivel plate at the beginning of the welding operation; the welding electrodes are held in oblique position, tipped somewhat from the vertical, and by gradually melting down they approach a vertical position. This prevents short-circuiting between one or more welding electrodes and a roll having a body of considerable length along which the electrodes initially extend.
