The method involves realizing individual carcass portions, which form a carcass (2) in an assembled state, where the portions are assembled by laser welding using electron beam. The carcass is assembled based on two parts such as left half-carcass (8A) and a right half-carcass (8B). The individual carcass portions are manufactured by a semi-solid foundry process i.e. Rheocasting process, hot forging process, or injection process and deprived of strengthening ribs. An independent claim is also included for a mold for manufacturing an aluminum single-piece carcass for a rifle. |
