FIELD: sheet forming in machine engineering, namely making laminate blanks for drawing parts with damping properties. SUBSTANCE: method comprises steps of charging to punching die set layers of blank in the form of metallic sheets or strips with vibration damping layer between them; mutually joining layers by punching at forming vertical burr in zones of least motion of blank flange; in first variant of invention using synthetic film as vibration damping layer; welding blank layers after punching; before punching marking out welding places for subsequent cutting out film according to them; in second variant of invention using "metal-paste" as vibration damping layer; welding blank layers after punching; applying paste onto surface of each sheet or strip except welding places marked out with the aid of stencil on upper sheet or strip. EFFECT: enhanced quality of parts made of such blanks. 2 cl
