저입열 방식의 일렉트로 슬래그 용접장치{A Low Heat Input Type of Electro Slag Welding Apparatus}Low Heat Input Electro Slag Welding Apparatus {A Low Heat Input Type of Electro Slag Welding Apparatus}

본 발명은 일렉트로 슬래그 용접장치에 관한 것으로서, 특히 선박의 외판 등을 용접하기 위해 구성한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electroslag welding apparatus, and in particular, is configured for welding an outer plate of a ship.

조선분야에서는 선체 두꺼운 외판 등을 일렉트로 가스 용접방식으로 용접한다. 일렉트로 가스 용접은 과다한 용접입열량, 아크에 의한 작업자의 피로감, 스패터에 의한 팁의 손상, 팁의 손상으로 인한 아크의 불안정 등의 문제점이 있다.In shipbuilding, thick hull shells are welded by electrogas welding. Electro gas welding has problems such as excessive heat input of the welding, fatigue of the operator due to the arc, damage of the tip by the spatter, and instability of the arc due to the damage of the tip.

한편, 일렉트로 슬래그 용접은 아크 및 스패터의 발생이 없는 저항용접의 일종으로서, 일렉트로 슬래그 용접의 장점을 기반으로 건설분야에서 적용되고 있다. 일렉트로 슬래그 용접방식에 따른 용접 두께는 20 내지 500mm이다.On the other hand, electro slag welding is a kind of resistance welding without the generation of arc and spatter, and has been applied in the construction field based on the advantages of electro slag welding. Welding thickness according to the electro slag welding method is 20 to 500mm.

하지만, 이와 같은 일렉트로 슬래그 용접을 선박용접에 적용하지 못하는 까닭은, 용접입열량이 높기 때문이다.However, the reason why such electro slag welding is not applied to ship welding is because the heat input of welding is high.

본 발명은 앞에서 설명한 바와 같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, 선박의 외판 등을 수직 상승하며 용접할 수 있게 구성한 저입열 방식의 일렉트로 슬래그 용접장치를 제공하는 데 그 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, an object of the present invention is to provide a low heat input type electric slag welding apparatus configured to weld the outer plate and the like vertically.

And an additional wire extending into the welding space formed by the two ship steel plates, the backing material and the copper filler, an electrode wire extending into the welding space, and a power supply for supplying power to the electrode wire. Moving upward along the welding is characterized in that the welding by the power supplied to the electrode wire.

또한, 본 발명의 바람직한 실시예에 따르면, 상기 전극와이어와 상기 첨가와이어는 모터가 장착된 릴에 감겨지며 상기 모터의 회전에 따라 상기 전극와이어와 상기 첨가와이어의 송급속도가 제어된다.In addition, according to a preferred embodiment of the present invention, the electrode wire and the additional wire is wound on a reel equipped with a motor and the feeding speed of the electrode wire and the additional wire is controlled according to the rotation of the motor.

There is an advantage that can be prevented in advance due to equipment damage and welding failure.

또한, 본 발명의 저입열 방식의 일렉트로 슬래그 용접장치는 첨가와이어에 전원을 공급하지 않아도 됨에 따라 장비를 간소화할 수 있다는 장점이 있다.In addition, the electrothermal slag welding apparatus of the low heat input method of the present invention has the advantage that the equipment can be simplified as it does not need to supply power to the additional wire.
