METHOD OF VERTICAL ELECTROSLAG SURFACING Russian patent published in 1994 - IPC

FIELD: electroslag manufacturing to produce overlaid metal resistant to striking-abrasive wear. SUBSTANCE: welding process is made with strip electrode, fusing end of witch is moved upward and concurrently moved away from the surface being covered according to the dependency presented in the description. Trajectory of the fusing strip electrode when it moves away from the surface being overlaid is set by relationship presented in the description. Besides, the strip electrode is made in the form corresponding to the front and lateral sides of the surface being overlaid with total width (perimeter) of the lateral sides of the strip along all its width specified within limits presented in the description. EFFECT: increased quality of the overlaid layer at the expense of decreased share of the base metal compared to welded up one, possibility to control geometric dimensions and shape of the metal being overlaid. 3 cl, 6 dwg, 2 tbl
