FIELD: welding. SUBSTANCE: method involves welding additive powder in indirect-action plasma arc, which is supplied by power from current source with drooping characteristic; providing positioning of built-up layer on preliminarily prepared cutting edge of surgical scissors, with cutting edge having variable thickness; heating cutting edge surface and built-up welding it in direct-action arc. Power is supplied to arc from current source with fixed characteristic. Self-adjustment coefficient of current source is set in accordance with ratio recited in specification. EFFECT: increased wear-resistance of cutting tools. 2 dwg, 1 tbl
