A method for replacing a fuse casing ( ), which is riveted to the casing ( ) of an active component ( ) containing an explosive charge ( ). The new fuse casing ( ) laser-welded to the remaining rivet parts ( ) of the active component casing ( ). Welding filler materials are used to attach the new fuse casing ( ) easily and securely to the active component casing ( ), such that the connection can withstand even high firing accelerations, without this resulting in impermissibly high thermal stress to the explosive charge ( ) in the active component. Welding powders ( ) or welding pastes can be used as welding filler materials, which are inserted into gaps ( ) remaining between the remaining rivet parts ( ) and the bores ( ) in the fuse casing ( ) before the remaining rivet parts ( ) are welded to the fuse casing ( ). Also used are discs ( ) that cover the bore holes ( ) in the fuse casing ( ). The disks are placed onto the frontal faces of the remaining rivet parts ( ) and are welded to these.

Method for replacing a fuse casing

A method is described for producing a line-shaped weakening in a flat material by one-sided local removal of the flat material by controllable pulsed laser radiation. The occurring line-shaped weakening is not visible on the surface of the flat material that is not machined and has a reproducible constant breaking resistance.
