본 발명은 고능률 후판 양면 동시 일렉트로가스 입향 용접장치에 관한 것으로, 보다 상세하게는 선박의 후판과 같은 판계작업을 행할 시 일렉트로가스 입향 용접장치를 이용하여 고능률의 후판양면 동시작업이 가능한 일렉트로가스 입향 용접장치에 관한 것이다.
The present invention relates to a high-efficiency thick plate double-sided simultaneous electrogas directional welding device, and more particularly, to a high-efficiency thick plate double-sided work by using an electrogas directional welding device when performing plate work such as a ship's thick plate. It relates to a longitudinal welding device.

통상 용접은 접합하려는 두 금속재료 즉, 모재(base metal)의 접합부를 가열하여 용융 또는 반용융상태로 하여 모재만으로 또는 모재와 용가재(filler metal)을 융합하여 접합하는 방법이다.In general, welding is a method in which a joint between two metal materials to be joined, that is, a base metal, is heated to be in a molten or semi-melt state and joined by only a base material or by fusing a base material and a filler metal.

또한, 작은 판재를 연결하여 넓은 판을 형성하기 위한 용접작업(이하 판계작업이라 칭함)을 행할 시 인접된 모재들이 'X' 자 형상의 개선을 형성토록 하여 상기 'X' 자의 개선을 따라 상면 및 하면의 양면용접을 행하도록 하고 있다.In addition, when the welding work for forming a wide plate by connecting a small plate (hereinafter referred to as a plate-based work), the adjacent base materials to form an 'X' shape improvement, so that the upper surface and Both surfaces of the lower surface are welded.

특히, 대형선박과 같은 선체의 상판은 응력의 집중부분으로 일정두께를 갖는 후판이 사용되어 지며, 상기 후판은 작은 판재를 통해 판계작업을 거친 후 블록으로 제작되게 된다.
In particular, the upper plate of the hull, such as a large vessel is used as a thick plate having a certain thickness as the concentrated portion of the stress, the thick plate is made into a block after a plate-based operation through a small plate.

상기와 같은 일반적인 판계작업의 용접방식의 한 형태로써 서브머지드아크 용접(Submerged Arc Welding : SAW)이 많이 사용되고 있으며, 이는 용접하고자 하는 용착부에 용제(Flux)를 도포한 후, 용접와이어를 송급하여 용접하는 방식이다.Submerged arc welding (SAW) is widely used as a form of welding in the general plate-based operation as described above. After the flux is applied to the weld to be welded, the weld wire is sent. This is a quick welding method.

이에 반해 본 발명에 적용된 일렉트로가스용접(Electro Gas Welding : EGW) 은 주로 이산화탄소(CO2)를 보호가스로 이용하여 아크를 발생시키며, 이 아크열로 모재를 용융시켜 각각의 모재를 접합하는 방식으로, 통상 모재의 전면과 후면에 설치된 수냉식의 동당금을 이용하여 냉각수를 공급하고, 용접토치로부터 송급되는 용접와이어와 모재간에 발생되는 아크를 통해 용접이 진행되는 방식이다.
In contrast, Electro Gas Welding (EGW) applied to the present invention mainly generates carbon using carbon dioxide (CO 2 ) as a protective gas, and in this manner, the base material is melted by the arc heat to bond the respective base materials. In this case, the cooling water is supplied using a water-cooled copper molten metal installed on the front and rear surfaces of the base metal, and the welding is performed through an arc generated between the welding wire fed from the welding torch and the base metal.

일반적으로 도 2 에서와 같이 상기 서브머지드아크 용접은 상기 판계작업을 행할 시 아래보기 자세를 취함에 따라 개선된 일면을 용접한 후, 모재를 턴오버시킨 다음 다시 타면을 용접하는 방식이 취하게 되며, 또한 다층용접방식 즉, 통상 20회 이상의 반복적인 용접공정이 이루져 생산성 저하의 요인이 되는 문제점이 발생되었다.Generally, as shown in FIG. 2, the submerged arc welding is performed by welding the improved one side according to the downward position when performing the plate-making operation, and then turning over the base material and then welding the other side again. In addition, a multilayer welding method, that is, a conventional welding process is repeatedly performed 20 times or more, which causes a problem of lowering productivity.

또한, 모재의 두께가 두꺼울수록 반복공정이 가중되는 문제점이 발생되었다.
In addition, the thicker the thickness of the base material has a problem that the weighting process is increased.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출되는 것으로, 그 목적은 상기와 같은 다층을 형성하는 반복용접공정의 번거로움을 해소하기 위해 도입된 일렉트로가스용접을 이용하여 아래보기 자세가 아닌 수직방향의 상진자세를 취하여 1회의 용접공정에 따른 판계작업의 효율성을 높일 수 있는 고능률 후판 양면 동시 일렉트로가스 용접장치를 제공함에 있다.
The present invention is devised to solve the conventional problems as described above, the object of which is not to look at the posture using the electrogas welding introduced to eliminate the hassle of the repeated welding process to form a multilayer as described above It is to provide a high-efficiency thick plate double-sided simultaneous electrogas welding device that can improve the efficiency of plate-making work by one welding process by taking a vertical upward position.
