Abstract
A multi-part casing for an ammunition cartridge comprising a tubular sleeve and a base, the base assembled and fixed to the tubular sleeve by a weld arrangement. The base comprises an end wall having a rim, an extraction groove adjacent the rim, and a tubular extension extending from the end wall and having an outer surface in contact with an inner surface of a base end of the tubular sleeve. The welding arrangement comprises a weld line that spirals around the base end of the tubular sleeve from a weld line start point positioned over the tubular extension of the base spiraling to a weld line end section positioned over the extraction groove, a surface portion of the extraction groove interfacing with the tubular sleeve having a machined surface such that the weld line ends in the machined surface.
