본 발명은 파이프 원주 용접을 위한 플라즈마 자동용접장치에 관한 것으로, 보다 상세하게는 파이프의 단관과 단관의 이음 원주 용접을 위하여 플라즈마 용접토치와 일반 용접토치로 구성된 복합 자동용접장치에 관한 것이다.The present invention relates to a plasma automatic welding device for pipe circumferential welding, and more particularly, to a composite automatic welding device consisting of a plasma welding torch and a general welding torch for welding the short pipe and the joint circumference of the pipe.

플라즈마를 이용한 용접은 높은 열원을 사용하여 국부적인 열 영향을 끼침으로 인해, 다른 일반 용접과는 달리 용접속도가 빠르고 열영향부가 좁아 변형과 조직의 성질변화가 적다는 이점이 있다. 그러나 플라즈마의 아크 특성상 토치의 높이에 민감하며, 아크를 안정화시키기 위해서는 토치높이가 일정하게 유지되는 것이 요구된다.Plasma welding has the advantage that due to the local heat effect using a high heat source, unlike other welding, the welding speed is fast and the heat affected zone is narrow, so that there is little deformation and change in the properties of the structure. However, the arc characteristics of the plasma are sensitive to the height of the torch, and the torch height is required to be kept constant to stabilize the arc.

일반적으로 파이프 제조공정에 있어서 플라즈마 용접은 곡면으로 성형된 부재의 길이방향 용접에 많이 적용되고 있다. 그러나 이렇게 제조된 제품의 단관과 단관을 결합하는 원주 용접에 있어서 구경이 적은 튜브나 파이프류의 초층 용접은 티그용접이 적용되고 있으며, 초층을 제외한 나머지 적층은 티그용접을 그대로 사용하여 적층하거나, 개스 메탈 아크 용접법(GMAW) 혹은 플럭스 코어드 아크 용접(FCAW)법을 사용하여 나머지 개선에 대한 용접을 하고 있다. 실제 초층 용접에 사용되는 플라즈마의 용접속도는 티그용접에 비해 약 3배 정도 빠르다.In general, in the pipe manufacturing process, plasma welding is widely applied to longitudinal welding of curved shaped members. However, in the circumferential welding that combines the end pipe and the end pipe of the manufactured product, the tidal welding is applied to the first layer welding of tubes or pipes having a small diameter. Metal arc welding (GMAW) or flux cored arc welding (FCAW) methods are used to weld the remaining improvements. In fact, the welding speed of plasma used for superlayer welding is about three times faster than that of TIG welding.

이러한 복관 제작공정은 현재 대부분 티그용접을 적용하여 초층 용접에 적용하고 있으며, 나머지 적층용접은 티그용접을 적용할 경우 생산성이 낮고, 별도의 다른 장치에 있는 용접토치로 나머지 적층하는 것은 장치운용이 불편하다. 또한, 플라즈마 용접의 아크 안정화가 대단히 중요하다는 점에서 파이프의 진원도 오차에 따른 토치의 높낮이 조정을 대부분 수동으로 하고 있어서 용접결함 발생이라는 문제점이 있었다.Most of these pipe manufacturing processes are applied to the first layer welding by applying TIG welding, and the remaining laminated welding is low in productivity when TIG welding is applied, and it is inconvenient to operate the lamination with the welding torch in a separate device. . In addition, since the arc stabilization of plasma welding is very important, most of the height adjustment of the torch according to the roundness error of the pipe is made manually, resulting in a welding defect.

따라서 본 발명의 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 그 목적은 별도의 와이어가 공급되는 용접토치와 개스 메탈 아크 용접법(GMAW) 혹은 플럭스 코어드 아크 용접(FCAW)법에 사용되는 일반토치를 복합적으로 구성하여 플라즈마 용접으로 초층의 용접속도를 빠르게 하고, 일반 용접토치로 나머지 개선에 대해 용접을 실시함에 따라 생산성을 향상시키고, 파이프의 진원도 오차에 대응해 실시간으로 헤드의 높이가 최적의 높이로 자동 제어되어 양호한 용접품질이 유지될 수 있도록 하는 장치를 제공함에 있다.Therefore, the object of the present invention was devised to solve the above problems, the purpose of which is a general torch used in a welding torch and gas metal arc welding (GMAW) or flux cored arc welding (FCAW) method is supplied with a separate wire. To increase the welding speed of the first layer by plasma welding, improve the productivity by welding the remaining improvement with the general welding torch, and to raise the head height in real time in response to the roundness error of the pipe. It is to provide an apparatus that can be automatically controlled to maintain a good welding quality.

상기 목적을 달성하기 위하여, 본 발명은 바퀴를 구비하고 주행레일(100)을 따라 이동가능하게 설치되는 대차(102)와 상기 대차(102)의 상면에 설치되어 프라즈마 및 일반 용접기능을 수행하는 플라즈마 용접기(103)와 일반 용접기(104) 및 상기 플라즈마 용접기(103)와 일반 용접기(104)의 구동 및 장치의 전반적인 제어기능을 수행하는 제어장치반(105); 상기 대차(102)의 상면에 설치되는 컬럼 회전기어(106)와 상기 컬럼 회전기어(106)의 상면에 전단부가 고정 설치되어 90도의 범위내에서 회전가능하게 설치된 컬럼(107); 상기 컬럼(107)의 상단에 일단부가 고정 설치되어 수평의 구조를 하고 있는 붐대(200); 상기 붐대(200)의 일측에 설치된 두개의 헤드로 그 일측은 초층 용접을 위한 플라즈마 용접헤드로, 타측은 초층 위에 적층을 위한 용접헤드로 복합적으로 구성되는 헤드부(300); 용접될 파이프 단관(401)을 받쳐주되, 단관(401)을 회전시키면서 일정한 회전영역을 벗어나지 못하도록 상기 주행레일과 평행한 방향으로 설치되는 터닝롤러(402)와 상기 터닝롤러(402)를 구동시키기 위한 터닝롤러 구동모터(403)를 포함하여 구성된다.In order to achieve the above object, the present invention is equipped with a wheel and is provided on the trolley 102 and the upper surface of the trolley 102 which is installed to be movable along the running rail 100 to perform plasma and general welding functions A control unit 105 for driving the welding machine 103 and the general welding machine 104 and driving the plasma welding machine 103 and the general welding machine 104 and the overall control of the apparatus; A column 107 installed on the upper surface of the bogie 102 and a column 107 fixed to the upper end of the column rotary gear 106 so as to be rotatable within a range of 90 degrees; A boom 200 having one end fixed to an upper end of the column 107 and having a horizontal structure; Two heads provided on one side of the boom 200, one side of which is a plasma welding head for the first layer welding, the other side of the head portion consisting of a composite welding head for lamination on the first layer; Supporting the pipe end pipe 401 to be welded, but for driving the turning roller 402 and the turning roller 402 is installed in a direction parallel to the running rail so as not to leave a certain rotation area while rotating the end pipe 401 The turning roller drive motor 403 is configured.

In general, the improvement of I in (a) can be applied to a thin plate with a thin member, and the improvement in Y in (b) can be processed by welding the member when the thickness of the member is not sufficient to form the backside bead only by plasma welding.

The column 107 is structured to rotate by the column rotary gear 106.

각 헤드는 공통적으로 구동 슬라이드와 와이어 릴(312,322), 플라즈마 용접토치(315) 혹은 일반 용접토치(325) 및 레이저 변위센서(314,324)로 구성되어 있다. 붐대(200)에 설치된 리니어 가이드(203)를 따라 헤드가 전후로 움직이는 구조이며, 이것은 헤드 전후 구동모터(310,320)에 의해 붐대(200)에 고정된 피니언을 따라 헤드부(300)의 랙이 회전하면서 전후로 움직이게 되는 구조이다. 헤드상하, 좌우 구동은 리니어 가이드와 볼 스크류 방식에 의해 움직이는 구조로 되어 있다. 슬라이드 상단에는 와이어 릴(312,322)이 설치되어 있고, 헤드의 좌우 구동은 헤드 좌우 구동모터(311,321)에 의해 움직이는 구조이며, 하부의 토치부는 플라즈마 용접헤드인 경우, 플라즈마 용접토치(315)와 별도로 와이어가 공급되는 와이어 가이드 장치(316)가 설치되어 있어 필요시 용가재를 보충하여 용접할 수 있도록 되어 있다. 그러나 일반용접 헤드부에는 와이어 가이드가 필요 없으며, 와이어를 토치내부로 직접 송급할 수 있는 용접토치가 설치되어 있다.Each head is commonly composed of drive slides and wire reels 312 and 322, plasma welding torch 315 or general welding torch 325, and laser displacement sensors 314 and 324.

그리고 플라즈마 용접에 있어서 아크길이를 유지하는 것은 아크의 안정성을 위하여 대단히 중요하며, 이러한 아크길이 유지를 위해 헤드부(300)에 레이저 변위센서(314,324)를 설치하여 단관의 진원도에 따른 오차에 대응해 실시간으로 서보모터인 헤드 상하 구동모터(313,323)를 구동시켜 헤드의 높이를 제어할 수 있도록 하였으며, 용접방법은 개별헤드에 의해 플라즈마로서 초층용접을 한 뒤, 그 위에 개 스 메탈 아크 용접법(GMAW) 혹은 플럭스 코어드 아크 용접(FCAW)법인 일반용접이 적용되는 장치를 창출하였다.And maintaining the arc length in the plasma welding is very important for the stability of the arc, in order to maintain the arc length by installing laser displacement sensors (314,324) in the head portion 300 to cope with the error according to the roundness of the short pipe The height of the head can be controlled by driving the upper and lower driving motors (313, 323), which are servo motors in real time, and the welding method is a first layer welding as plasma by an individual head, and then a gas metal arc welding method (GMAW) thereon. Or, the company created a device to which general welding, a flux cored arc welding (FCAW) method, is applied.
