The invention provides a commercial-vehicle aluminum-alloy air storing cylinder without overlapped and cross welding joints. An air storing cylinder casing with the two ends open and air storing cylinder end covers are integrally welded, the air storing cylinder casing is a seamless cylinder body and an extrusion-forming integrated part, no straight welding joint can be found on the air storing cylinder casing, and only circumferential welding joints are formed at the connecting positions between the air storing cylinder end covers and the air storing cylinder casing. The technical scheme is further limited that used aluminum alloy materials are aluminum magnesium alloy with good rust-proof performance and the trademark of the used aluminum alloy materials is 5000 and 6000 series. The used aluminum alloy materials have good rust-proof performance, the air storing cylinder casing is formed by the materials of the trademark in an extruding or spinning forming manner, no welding joint is found on the air storing cylinder casing, and only circumferential welding joints are formed at the circumferential-welding connecting positions between the air storing cylinder casing and the air storing cylinder end covers. The welding joints are smooth and flat, and no overlapped and cross welding joint is generated. Thus, the air tightness and the compression strength of the air storing cylinder are improved, the service life of the air storing cylinder is prolonged, the appearance quality of the air storing cylinder is improved, and the producing efficiency is improved.
