FIELD: processes for electric arc fusion of parts under flux layer for restoring worn parts and for applying strengthening coatings onto new parts. SUBSTANCE: method comprises steps of preliminarily (before fusion) dividing part surface by separate portions in such a way that each portion is restricted with circle arcs or polygon having straight and(or) curvilinear sides; performing automatic fusion process separately for each portions of part surface. EFFECT: enhanced quality of coating fused onto surface of complex- shape articles, enhanced efficiency of fusion process. 18 dwg, 2 ex
