Field of the Invention The present invention relates to a high current twin wire electro gas welding apparatus, and to a high current twin wire electro gas welding apparatus capable of improving welding speed by using two welding wires simultaneously by one welding power source.

통상 용접은 접합하려는 두 금속재료 즉, 모재의 접합부를 가열하여 용융 또는 반용융상태로 하여 모재만으로 또는 모재와 용가재를 융합하여 접합하는 것으로, 대형선박과 같이 일정두께를 갖는 블록의 용접시에는 일렉트로 가스용접(EGW)이 널리 사용되고 있다. In general, welding involves joining two metal materials to be joined, namely, a base material to be melted or semi-melted, and joining only the base material or by fusion of the base material and the filler metal. Gas welding (EGW) is widely used.

상기 일렉트로 가스용접은 수직전용용접이라는 점에서는 일렉트로 슬랙용접과 같지만 사용되는 열원이 아크이며, 수냉동판으로 용접부위를 둘러싸고 그 안으로 이산화탄소, 이산화탄소-아르곤, 아르곤-산소 등의 보호가스를 집어넣고 보호가스 분위기를 만든 이후에 와이어 가이드 노즐을 통하여 용접와이어를 송급하여, 용접와이어 끝과 모재간에 발생하는 아크에 의해, 용접와이어와 모재를 용융하여 용접을 진행한다. 즉, 일렉트로 가스용접은 모재의 전면에 설치된 수냉식 동담금을 이용하여 냉각수를 공급하고, 후면에는 백킹재를 설치하며, 용접토치로부터 송급되는 용접와이어와 모재간에 발생하는 아크를 통해 용접이 진행되는 방식이다. The electro gas welding is the same as the electro slack welding in that it is a vertical exclusive welding, but the heat source used is an arc, and the protection gas such as carbon dioxide, carbon dioxide-argon, argon-oxygen, etc. After creating the atmosphere, the welding wire is fed through the wire guide nozzle, and the welding wire and the base metal are melted by an arc generated between the tip of the welding wire and the base metal to perform welding. That is, the electro-gas welding is to supply the cooling water by using the water-cooled copper filler installed on the front of the base material, the backing material is installed on the back, the welding proceeds through the arc generated between the welding wire supplied from the welding torch and the base material to be.

그러나, 종래의 일렉트로 가스용접장치는 한 가닥의 와이어를 사용하여 약 400 Amp 이하의 용접전류로 용접을 하도록 되어 있어, 용접속도가 느리고 이로 인해 작업성 및 생산성이 저하되는 등 여러가지 문제점이 있었다. However, the conventional electro-gas welding apparatus is welded with a welding current of about 400 Amp or less by using a single wire, and thus has a variety of problems such as slow welding speed and workability and productivity.

본 발명은 상기와 같은 문제점을 해소하기 위한 것으로, 그 목적은 2가닥의 용접와이어를 이용하여 일렉트로 가스용접을 행하고, 이를 통해 용접속도 및 작업성을 향상시킬 수 있는 대전류 트윈와이어 일렉트로 가스용접장치를 제공하는 것이다. The present invention is to solve the above problems, the object of the present invention is to perform a gas welding using two welding wires, through which a high current twin wire electro gas welding apparatus that can improve the welding speed and workability To provide.
