일반적으로 선박 건조 과정에서 용접 공정은 건조 공정의 약 60%를 점유하는 중요한 공정 중의 하나이며, 선박 생산은 여러 형상의 선체블록들을 독립적으로 제작한 다음 이들 블록들을 도크(Dock)에서 서로 합하는 방식으로 이루어진다. 즉 중, 대형 선박 1척을 건조하는데 250?400개의 선체블록들이 만들어지며, 선체 블록 내부에는 용접셀이 약 200개(셀마다 수직 용접부 2개 존재) 정도가 존재하므로 1척의 선박을 건조하기 위해서는 무수히 많은 수직교차부들을 용접해야 한다In general, the welding process in shipbuilding is one of the important processes that occupy about 60% of the building process, and ship production is made by making hull blocks of various shapes independently and then combining them in a dock. Is done. That is, 250 ~ 400 hull blocks are made to build one medium and large ship, and there are about 200 welding cells (two vertical welds per cell) in the hull block. We need to weld a myriad of vertical cross sections.

이러한 선체 블럭 내부에는 T자형 필렛(Filet) 용접이 많이 이루어지며, 수직으로 용업 작업을 진행하여야 하는 경우도 있다.In the hull block, many T-shaped fillet (Filet) welding is made, there is a case that the industrial work must be carried out vertically.

마지막으로, 상기 캐리지 몸체(100)에는 손잡이(150)이 설치되어 작업자가 상기 손잡이(150)를 잡고 상방향으로 진행하면서 용접을 수행할 수 있도록 한다.Finally, the handle 150 is installed on the carriage body 100 to allow the operator to carry out welding while holding the handle 150 to proceed upward.

도 3은 본 발명의 바람직한 일실시예에 따른 핸드 필렛 용접용 캐리지가 용접 부위에 접촉되는 상태를 도시하는 예시도이다.3 is an exemplary view showing a state in which the carriage for hand fillet welding is in contact with the welding site according to an embodiment of the present invention.

도 3에 도시된 바와 같이 제1 소재(10)와 제2 소재(20)가 수직으로 접합되는 부위에 용접선이 형성되며, 한 쌍의 구동휠(110)과 한 쌍의 가이드휠(130) 각각은 상기 제1 소재(10)와 제2 소재(20)의 내측면에 밀착된다.As shown in FIG. 3, a welding line is formed at a portion where the first material 10 and the second material 20 are vertically bonded to each other, and the pair of driving wheels 110 and the pair of guide wheels 130, respectively. Is in close contact with inner surfaces of the first material 10 and the second material 20.

다음으로, 본 발명에 따른 핸드 필렛 용접용 캐리지를 이용한 작업 방법에 대해 살펴보기로 한다.Next, a working method using a carriage for hand fillet welding according to the present invention will be described.

도 4는 본 발명의 바람직한 일실시예에 따른 핸드 필렛 용접용 캐리지를 이용한 작업예시도이다.Figure 4 is a working example using a carriage for hand fillet welding according to an embodiment of the present invention.

도 4에 도시된 바와 같이 수직으로 접합되는 제1 소재(10)와 제2 소재(20) 하단부로부터 용접이 진행되며, 상방향으로 캐리지가 이동되면서 용접 작업이 진행된다.As shown in FIG. 4, the welding proceeds from the lower end of the first material 10 and the second material 20 which are vertically joined, and the welding operation proceeds while the carriage moves upward.

이때, 작업자는 손잡이(150)를 잡은 상태에서 한 쌍의 구동휠과 한 쌍의 가이드휠(130)이 제1 소재(10) 및 제2 소재(20)에 밀착되도록 전방으로 약간의 힘을 가하게 되면, 구동 모터에 의해서 구동되는 구동휠에 의해서 캐리지 자체가 상방향으로 이동되면서 용접 작업을 수행하게 된다. At this time, the operator applies a slight force forward so that the pair of driving wheels and the pair of guide wheels 130 in close contact with the first material 10 and the second material 20 while holding the handle 150. When the carriage itself is moved upward by the driving wheel driven by the driving motor, the welding operation is performed.

특히, 본 발명에 따른 핸드 필렛 용접용 캐리지는 종래의 캐리지와 달리 가이드 레일의 설치가 필요하지 않으므로 비용접 구간(s)이 캐리지 자체의 간섭으로 인하여 용접 토치가 더 이상 진행될 수 없는 구간을 제외하고는 용접 작업을 진행할 수 있다. In particular, the carriage for hand fillet welding according to the present invention does not require the installation of the guide rail, unlike the conventional carriage, except for the section where the welding torch can no longer proceed due to the interference of the carriage itself (s). Can proceed with the welding operation.

이상과 같이 본 발명은 핸드 필렛 용접용 캐리지를 제공하는 것을 주요한 기술적 사상으로 하고 있으며, 도면을 참고하여 상술한 실시 예는 단지 하나의 실시 예에 불과하므로 본 발명의 진정한 범위는 특허청구범위에 의해 결정되어야 한다.
As described above, the present invention has a main technical idea to provide a carriage for hand fillet welding, and the embodiment described above with reference to the drawings is only one embodiment, so the true scope of the present invention is defined by the claims. It must be decided.
