Abstract
A method for the application of rotating bands on a projectile body comprises winding at least one layer of a first ribbon-like material around the projectile body; fastening the ribbon-like material on the projectile body by applying a laser or electron beam in a deep-penetration welding process; and giving the beam an intensity so that only a small zone near the surface of the projectile body is melted to the ribbon-like material.
