FIELD: different branches of machine engineering and metallurgy, possibly working products for modifying or preparing topography of article surface or raw materials.
SUBSTANCE: method comprises steps of relatively moving article and powerful beam in crossing direction in order to act upon several positions on article by means of said beam; at each position moving beam relative to article according to predetermined way; melting material of article and moving it by action of powerful beam for forming recesses or openings; joining article having prepared surface with target part. Product formed by such process has predetermined surface roughness.
EFFECT: possibility for producing article with predetermined surface roughness.
