An automated piping spool manufacturing system is disclosed. An automated piping spool manufacturing system according to an embodiment of the present invention may comprise: a pipe cutting unit comprising a pipe cutter for cutting a raw pipe into a desired length, thereby obtaining a spool pipe; a spool pipe groove processing unit comprising a spool pipe groove processor for forming a weld groove on an end of the spool pipe; a connecting member groove processing unit comprising a connecting member groove processor for forming a weld groove on an end of a connecting member; a straight pipe spool manufacturing unit comprising a straight pipe welder and a welding robot such that the connecting member is welded to the spool pipe, thereby making a straight pipe spool; a stereoscopic spool manufacturing unit comprising a stereoscopic spool welder and a welding robot such that the connecting member or another straight pipe spool is welded to the straight pipe spool, thereby making a stereoscopic spool; a handling unit comprising a handling robot and a gantry crane robot such that, when the spool pipe, the connecting member, the straight pipe spool, or the stereoscopic spool is moved or welded, the connecting member or the straight pipe spool is held; and a control unit for controlling each of the pipe cutting unit, the spool pipe groove processing unit, the connecting member groove processing unit, the straight pipe spool manufacturing unit, and the stereoscopic spool manufacturing unit, and the handling unit when information regarding a piping spool is input thereto such that the piping spool is manufactured according to the input information without an operator’s intervention or a separate written material.
