Abstract: A method of laminating a plurality of metal plates one to another, comprising steps of (a) arranging at least first and second generally planar metal plates having exposed surfaces into a spaced apart parallel relationship with one another, (b) anchoring the spaced apart plates to a fixed location, and (c) propelling a projectile against the exposed surface of the first plate with sufficient velocity to create a spot impact between the first and second plates of sufficient energy to create a metallurgical weld between the plates at the point of projectile impact.
