Disclosed is a device for bonding a liner for a hydrogen tank. The device for bonding a liner for a hydrogen tank according to one exemplary embodiment of the present invention is configured to bond a first liner part and a second liner part made of a plastic material and may comprise: i) a jig frame; ⅱ) a pair of moving members installed to be movable to get farther away from or closer to the jig frame; ⅲ) a part mounting unit installed on each of the pair of the moving members such that the first liner part and the second liner part are mounted respectively on the pair of the moving members; ⅳ) a core ring made of steel interposed between a first bonded end portion of the first liner part and a second bonded end portion of the second liner part, which are overlapped with each other; ⅴ) an induced heating unit installed on the jig frame and disposed to be spaced apart by a pre-set gap from a joint portion between the first bonded end portion and the second bonded end portion where the core ring is sandwiched. Accordingly, the pair of the liner parts can be melt-joined by induction heating. 수소탱크용 라이너 접합 장치가 개시된다. 개시된 본 발명의 예시적인 일 실시 예에 따른 수소탱크용 라이너 접합 장치는, 양분된 플라스틱 소재의 제1 라이너 파트와 제2 라이너 파트를 접합하도록 되어 있는 것으로서, ⅰ)지그 프레임과, ⅱ)지그 프레임에 서로 멀어지거나 가까워지는 방향으로 이동 가능하게 설치되는 한 쌍의 이동 부재들과, ⅲ)한 쌍의 이동 부재들의 각각에 제1 라이너 파트와 제2 라이너 파트를 장착하도록 한 쌍의 이동 부재들의 각각에 설치되는 파트 장착 유닛과, ⅳ)서로 겹쳐지는 제1 라이너 파트의 제1 접합 단부 및 제2 라이너 파트의 제2 접합 단부의 사이에 배치되는 스틸 소재의 코어 링과, ⅴ)지그 프레임에 설치되며, 코어 링이 개재된 제1 접합 단부 및 제2 접합 단부의 이음부와 설정된 갭을 두고 배치되는 유도 가열 유닛을 포함할 수 있다.
