Zusammenfassung:	Disclosed is a method of improving the weldability of hot stamping parts, which can improve the weldability of hot stamping parts of reduced weldability due to a surface oxide. The method of improving the weldability of hot stamping parts according to one embodiment of the present invention comprises: a welding site selection step for selecting a welding site in a hot stamping part; a surface oxide layer removal step for removing a surface oxide layer of the welding site; and a hot stamping part welding step for welding the welding site of the hot stamping part from which the surface oxide layer has been removed.
