FIELD: processing metallic structures to scrap metal, particularly at recovering military ammunition and equipment. SUBSTANCE: method comprises steps of applying on surface of metallic structure electrically insulated coating and cutting it through until metal surface; placing with gap non-insulated tool-electrode connected with negative pole of electric current source; placing metallic structure to electrolytic bath; making in metallic structure cutout whose depth and width are technologically proved; then applying on lateral surfaces of cutout electrically insulated coating while remaining non-insulated bottom of cutout; successively repeating all operations until complete cutting of metal; using polyethylene film as electrically insulated coating. EFFECT: enhanced efficiency of cutting process. 2 cl, 5 dwg
