Abstract

A method of providing a high-explosive projectile with desired areas of fragmentation includes the following steps: securing a steel plate component in a circumferentially extending recess in the outer surface of a projectile body; directing an energy beam to outer surface portions of the steel plate component; heating, by the energy beam, narrow zones to a temperature above the melting temperature of the steel plate component to a predetermined depth thereof; and cooling the heated zones for effecting structural metallurgical changes in the steel plate component for obtaining the desired areas of fragmentation.
