Abstract
The present invention relates to a method used for manufacturing projectiles or other ammunition units such as artillery shells, and specifically to fastening a driving band (10) and/or a pipe cap (13) to the projectile body (1). In order to obtain a strong joint between the driving band (10) and the projectile body (1) as well as a simple manufacturing method the driving band (10) with the pipe cap (13) are fastened to the rear part of the projectile body (1) simultaneously, i.e. in the one and same working operation, by means of explosive cladding. The driving band and pipe cap material (7) formed as a 'cup' is disposed on the rear part of the projectile body after which detonating explosive (8) with a very high pressure joins the material (7) to the outer surface of the projectile body. The clad material is then machined to form the driving band (10), circumferential grooves (14, 15) and the pipe cap (13) into their desired dimensions.
