A magnet having the same shape as the inner circumference of the metal tube is inserted into the metal tube having a protrusion formed therein so that the inner portion is not separated, and one side of the metal plate having a predetermined length in the shape of a plane is connected to the upper side of the metal tube, and the upper side of the metal tube The connection part of the metal plate is joined by arc welding, and the other end of the metal plate is coupled to a connection terminal for connecting an electric wire, and a bolt hole is formed at the site where the metal plate and the connection terminal are connected to fix the metal plate and the connection terminal.

일반적으로 용접법은 화학적 또는 전기적으로 공급되는 열에 의해 재료를 일부 녹여서 융합시키는 방법으로, 용가재(filler material)가 사용되는 경우와 사용되지 않는 경우가 있다. 이러한 용접법은 용접공정의 주종을 이루고 있으며, 소모성 및 비소모성 전극을 이용한 아크용접과 고에너지 빔용접법이 있다.In general, the welding method is a method in which a material is partially melted and melted by heat supplied chemically or electrically, and sometimes a filler material is used or not used. These welding methods are mainly used for welding processes, and arc welding and high energy beam welding using consumable and non-consumable electrodes.

상기 아크용접은 가장 오래되고 간단하며 유용한 용접법중의 하나로, 현재 공업용 용접의 50%정도가 이 방법에 의해이루어지고 있다.Arc welding is one of the oldest, simplest and most useful welding methods, and about 50% of industrial welding is currently performed by this method.

아크용접은 피용접봉의 끝을 피용접부에 접촉시켜서 전기아크를 발생시키며 일정한 거리를 유지하며, 용접선(Weld line)을 형성한다. 이때, 용접봉의 끝부분은 전극집게에 고정한다.Arc welding generates the electric arc by contacting the end of the welding rod to the portion to be welded, maintaining a constant distance, and forms a weld line. At this time, the end of the electrode is fixed to the electrode clamp.

상기 전극집게는 전원의 한쪽 극에 연결시키고, 다른 한쪽 극은 피용접물(공작물)에 연결시킨다.The electrode clamp is connected to one pole of the power supply, and the other pole is connected to the workpiece (workpiece).

상기 아크용접의 전원으로는 주로 50A - 300A의 전류가 이용되며, 전력량은 10kW이내로 사용된다.The power of the arc welding is mainly used a current of 50A-300A, the amount of power is used within 10kW.

상기 아크용접에 사용되는 전류는 교류나 직류가 사용되고, 판재의 용접에는 아크가 안정적으로 유지되는 직류를 사용하며, 두꺼운 단면을 용접하는 경우에는 아크가 급속히 맥동함으로써 대직경의 용접봉에 최대전류를 사용할 수 있는 교류전류를 사용한다.The current used in the arc welding is used alternating current or direct current, the direct current of the plate is used to maintain the arc stably, and when welding a thick cross section, the arc pulsates rapidly to use the maximum current for large diameter welding rods Use alternating current.

한편, 직류전류를 사용하는 경우에는 극성, 즉, 전극의 방향성이 중요하며, 이는 용접봉의 형태, 피용접법물의 종류, 아크의 분위기, 가열층의 깊이에 따라 결정된다.On the other hand, in the case of using a DC current, the polarity, that is, the direction of the electrode is important, which is determined by the shape of the electrode, the type of the welded object, the atmosphere of the arc, the depth of the heating layer.

한편, 용접봉을 음극으로 하고, 공작물을 양극으로 하는 경우 정극성 (straight polarity)이라하고, 용접봉을 양극으로하고, 공작물을 음극으로 하는 경우 역극성(reverse polarity)이라 하며, 역극성인 경우에는 깊은 용입이 가능하다.On the other hand, when the electrode is used as the cathode and the workpiece is used as the anode, it is called polarity, and when the electrode is used as the anode, the work is used as the cathode, it is called reverse polarity. Intrusion is possible.

상기와 같은 아크용접에 필요한 장치로는 동력원, 동력선, 전극집게 등이 있다.The apparatus required for such arc welding includes a power source, a power line, and electrode clamps.

그러나, 집게형상인 접지전극은 이용시 항상 집게로 용접부와 연결된 금속부위에 연결하여야 하며, 이러한 연결 방법은 집게의 고장시 금속물체에 집게를 물릴수 없으며 금속물체에 분리와 결합이 불편하게 된다.However, tongs-shaped ground electrode should always be connected to the metal part connected to the welding part with tongs when used, this connection method can not be clamped to the metal object in the event of the failure of the tongs, and the separation and coupling to the metal object becomes inconvenient.

본 고안은 상기의 문제점을 해결하고자 안출된 것으로서, 원통형의 금속관의 상측에 금속판을 접합하고, 금속관 내부에 자석을 삽입하며, 상기 자석이 분리되지 않도록 금속관의 하측에 돌출부가 형성되고, 상기 금속관의 상측에 아크용접으로 금속판이 접합되며, 상기 금속판의 타측에 아크용접기의 접지선이 연결되는 접지단자가 볼트로 금속판과 결합되어지는 아크용접기의 자석 부착식 접지전극을 제공하는데 있다.The present invention has been made to solve the above problems, the metal plate is bonded to the upper side of the cylindrical metal tube, a magnet is inserted into the metal tube, the projection is formed on the lower side of the metal tube so that the magnet is not separated, The metal plate is bonded to the upper side by arc welding, and the other end of the metal plate provides a magnetized ground electrode of the arc welder, in which a ground terminal to which the ground wire of the arc welder is coupled to the metal plate by bolts.
