Description

2전극 일렉트로가스 용접용 수냉식 동당금{Water cooled copper backing for 2 electrod eledtro gas welding} Water cooled copper backing for 2 electrod eledtro gas welding

본 고안은 2전극 일렉트로가스 용접용 수냉식 동당금에 관한 것으로, 보다 상세하게는 2전극 일렉트로가스 용접시 배출되는 슬래그의 배출을 용이토록 한 수냉식 동당금의 형상에 관한 것이다.The present invention relates to a water-cooled copper molten metal for two-electrode electrogas welding, and more particularly, to the shape of a water-cooled copper molten metal for facilitating the discharge of slag discharged during two-electrode electrogas welding.

통상 2전극 일렉트로가스용접(Electro Gas Welding:EGW)은 나란히 세워진 모재의 용접부를 대향하며 모재에 형성된 'V'형의 용접부를 따라 아래에서 상방으로 상진하며, 이산화탄소(CO2)를 보호가스로 이용하여 아크를 발생시키며, 이 아크열로 모재를 용융시켜 각각의 모재를 접합하는 방식으로, 통상 세워진 상태로 설치된 모재의 전면에는 표면 동당금을 설치하고, 후면에는 백킹(backing)재를 이용하여 용접시에 발생되는 용접열을 냉각하여 용융금속이 아래로 흘러내리는 것을 방지하도록 하고 있다.Normally, two-electrode Electro Gas Welding (EGW) is opposed to the welding part of the base material which is placed side by side, and is advanced upward from the bottom along the 'V' type welding part formed on the base material, and uses carbon dioxide (CO 2 ) as a protective gas. The arc heat is generated, and the base material is melted by the arc heat, and the respective base materials are joined to each other. A surface copper equivalent is installed on the front surface of the base material which is normally placed in a standing state, and the back surface is welded using a backing material. The welding heat generated at the time is cooled to prevent molten metal from flowing down.

이때 상기 표면 동당금은 입향 상진하는 일렉트로가스 용접장비와 연동하여 상진됨에 따라 용접을 수행하는 동시에 용접부의 냉각을 행하게 된다.At this time, the surface copper sugar is advanced in conjunction with the electrogas welding equipment which is vertically advancing, thereby performing welding and simultaneously cooling the welded portion.

하지만 상기 일렉트로가스 용접시 루트전극과 표면전극으로 이루어진 2 전극의 용접재료로써 플럭스 코어드 와이어(Flux cored wire)를 사용하게 될 경우 다량의 슬래그(slag)가 생성됨에 따라 용접작업의 중간 이러한 슬래그를 제거한 후 다시 용접작업을 수행하게 되었다.However, when the flux cored wire is used as the welding material of the two electrodes consisting of the root electrode and the surface electrode during the welding of the electrogas, a large amount of slag is generated. After removal, welding was performed again.

또한, 특히 상기와 같이 일렉트로가스 용접장비는 개선부에 밀착되어 용접장비와 연동으로 상진하는 동당금이 슬래그의 배출을 막게 되며, 이렇게 용접부에 잔존하게 되는 슬래그가 용접 전극 및 동당금에 부착되어 전체적으로 용접품질을 저해하고 작업효율을 떨어지게 만드는 문제점이 발생되었다.In addition, as described above, the electrogas welding equipment is in close contact with the improved part, and the copper sugar advancing in conjunction with the welding equipment prevents the slag from being discharged. Thus, the slag remaining in the welding part is attached to the welding electrode and the copper sugar as a whole. Problems occur that impair welding quality and reduce working efficiency.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 안출되는 것으로, 그 목적은 일렉트로가스 용접을 통한 모재의 용접시 생성되는 슬래그의 배출이 원활히 이루어지도록 하여 작업의 효율향상 및 용점품질을 향상시킬 수 있도록 한 2전극 일렉트로가스 용접용 수냉식 동당금을 제공함에 있다. The present invention is devised to solve the conventional problems as described above, the purpose of which is to facilitate the discharge of slag generated during welding of the base material through the electrogas welding can improve the efficiency of the work and the quality of melting point. To provide a water-cooled copper equivalent for two-electrode electrogas welding.

상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 고안은 모재의 용접부를 따라 일측에서 타측으로 상방 진행하며 일렉트로가스용접(Electro Gas Welding:EGW)을 수행하는 용접 장치와, 이 용접 장치와 연동 이동하며 용접되는 모재의 용접부를 냉각시키는 수냉식 동당금에 있어서; 상기 모재의 용접되는 용접부를 향하게 되는 동당금 일면 가장자리 양단은 모재에 밀착되는 밀착부를 이루며, 이 밀착부의 사이구간인 중앙부는 용접된 후 양호한 비드를 형성토록 한 비드형성부가 형성되고; 상기 동당금의 비드형성부의 하단 양측에는 상호 대칭되게 내측으로 함몰시킨 함몰부를 형성한 것을 특징으로 한다.The present invention to achieve the object as described above and to perform the problem for removing the conventional defects and the welding device for performing the Electro Gas Welding (EGW) and proceeds upward from one side to the other side along the welding portion of the base material In the water-cooled copper sugar to cool the welded portion of the base material to be welded in movement with the welding device; Both ends of the copper-coated one-sided edge facing the welded portion of the base material form a close contact portion in close contact with the base material, and the center portion, which is an interval between the close contact portions, is welded to form a bead forming portion for forming good beads; On both sides of the lower end of the bead-forming portion of the copper sugar, it is characterized in that the depressions recessed inwardly symmetric with each other.
