Zusammenfassung:	Disclosed is a jig device for roll hardfacing welding which is installed on a roll hardfacing welding apparatus for performing hardfacing welding on an outer surface of a roll to prevent flux or melt from flowing down when performing hardfacing welding on an end portion of the roll to form a satisfactory weld state to eliminate a need for an additional welding process for the end portion of the roll. According to the present invention, the jig device for roll hardfacing welding comprises: a mounting jig which supports an end of a roll and is mounted on a roll hardfacing welding apparatus; a fixing bracket which is fixed on the mounting jig and has a first through hole; a moving bracket having a first hollow portion to allow one side of the mounting jig to pass therethrough; a screw bar wherein male screw threads are formed on an outer circumferential surface thereof, and one end thereof is mounted on the moving bracket while penetrating the first through hole; an adjustment nut mounted on the screw bar to adjust a separation distance between the fixed bracket and the moving bracket; and a guide plate of a copper material fit and mounted in the moving bracket. 본 발명은 롤의 외면에 대해 육성 용접을 수행하는 롤 육성 용접 장치(roll hardfacing welding apparatus)에 설치되어 롤의 단부 부위에 육성 용접을 수행할 때 플럭스나 용융물이 흘러내리는 것을 막아 롤의 단부 부위에서도 매우 양호한 용접 상태가 이루어지도록 함으로써 롤의 단부 부위에 대한 추가적인 용접 공정이 필요없도록 하는 롤 육성 용접용 지그 장치를 개시한다. 이를 위해, 본 발명에 따른 롤 육성 용접용 지그 장치는 롤의 단부를 지지하고 롤 육성 용접 장치에 장착되는 장착 지그와, 상기 장착 지그에 고정되고 제1관통공을 가지는 고정 브라켓과, 상기 장착 지그의 일측이 통과하도록 제1중공부를 가지는 이동 브라켓과, 외주면에 수나사산이 형성되고 상기 제1관통공을 관통하면서 일단부가 상기 이동 브라켓에 체결되는 스크류바와, 상기 스크류바에 체결되어 상기 고정 브라켓과 이동 브라켓의 이격 거리를 조절하는 조절 너트와, 상기 이동 브라켓에 끼워맞춤 결합되는 구리 재질의 가이드판을 포함한다.
