According to the light-weight oil tank and the rapid manufacturing process thereof, the light-weight oil tank is composed of a cylinder body and an end cover, and oil tank manufacturing can be rapidly achieved. The oil tank structure is formed by embedding two or more plug frames in the middle of a section of cylinder body; according to the rapid manufacturing and forming technology, firstly, the skin is prepared through horizontal extrusion, the plug frame is assembled, then primary metallurgical mechanical connection is completed through electromagnetic constraint, finally, secondary sealing of the oil tank plug frame is completed through laser welding, in the welding process, gapless welding and tool-free welding of the sealing structure can be achieved, and the welding qualification rate is greatly increased. The whole oil tank forming process can quickly realize assembly, and can effectively solve the problem of fuel oil sealing. 本发明公开了一种轻量化油箱及其快速制造工艺，其中，由筒身、端盖组成，可以快速实现油箱制造。本发明的油箱结构由一段筒身中间嵌入两个或多个塞框构成；其快速
