본 발명은 서브머지드아크용접(submerged arc welding: 이하 SAW) 위빙장치에 관한 것이다. 더욱 상세하게는 SAW 고전류 용접시 토치를 좌우로 일정간격으로 위빙하는 기구부를 구성함으로써 용접의 패스 수를 줄임과 동시에 용입 불량과 같은 용접 결함을 예방할 수 있는 SAW 위빙 장치에 관한 것이다. The present invention relates to a submerged arc welding (SAW) weaving device. More particularly, the present invention relates to a SAW weaving device capable of preventing welding defects such as poor penetration while reducing the number of passes of welding by forming a mechanism for weaving the torch at a predetermined interval from side to side during SAW high current welding.

일반적으로, 대형 선박이나 해양 구조물의 제작에 있어서 판과 판, 블록과 블록을 용접할 때 철판과 철판을 용접하게 된다. 이러한 철판의 용접은 비교적 입열이 적은 CO2용접으로 초층 용접을 1 ~ 3회 실시한 후 SAW 용접으로 마무리하게 된다. 이때, SAW 용접 패스를 두께에 따라 상이하지만 3 ~ 6패스 용접을 하게 된다.In general, in the production of large ships or offshore structures, when welding the plate and plate, block and block is to weld the iron plate and the iron plate. The welding of the iron plate is performed by the first layer welding once or three times with relatively low heat input CO 2 welding is finished with SAW welding. At this time, the SAW welding pass is different depending on the thickness, but the 3 ~ 6 pass welding.

특히, 아크 용접의 위빙은 주로 세경와이어를 사용하는 CO2용접 및 TIG 용접 등에 적용되어 왔다. 편면 맞대기 이음부의 용접의 경우 일정 갭을 주고 백킹재를 붙인 상태로 CO2용접을 하고 SAW 용접을 수행하게 된다.In particular, weaving of arc welding has been mainly applied to CO 2 welding, TIG welding, etc. using narrow wires. In the case of one-side butt joint welding portion to give a constant gap is the CO 2 welding in a state stuck to the backing material and perform a SAW welding.

CO2 용접 비드가 얕은 경우에는 강한 아크 열에 의해 CO2 용접 비드가 녹아버리게 되어 SAW 용접을 실시할 때에는 적정 전류 이상의 용접 전류를 사용하지 못하였다.When the CO 2 welding bead is shallow, the CO 2 welding bead is melted by the strong arc heat, so that the welding current more than the proper current cannot be used when performing the SAW welding.

또한, 초층 CO2용접을 2 ~ 3회 두껍게 하여 SAW 용접을 실시하는 경우 폭이 넓어 개선부가 완전히 녹지 않는 융입불량(lack of fusion) 문제로 여러 층으로 나뉘어 용접을 실시하였다.In addition, when the SAW welding was performed by thickening the superlayer CO 2 welding two or three times, the welding was performed by dividing into several layers due to a short of fusion problem in which the width of the improved part was not completely melted.

한편, 종래의 용접은 도 1의 (a)와 같이 용접 시공하였다. 일반적으로 갭을 벌려 비교적 용착량이 적은 CO2용접으로 첫패스에서 이면 용접을 하고, 그 위로 SAW 용접시 용락 방지를 위해 덧살을 붙이기 위한 용접으로 1 ~ 2패스 더 용접하였다.On the other hand, the conventional welding was welded as shown in Fig. 1 (a). In general, the gap was opened and the back side welded in the first pass by relatively small deposition amount of CO 2 welding, and then welded one or two more passes in order to prevent extinction during SAW welding.

CO2 용접이 끝나면 고용착 용접이 가능한 SAW 용접을 실시하는 데, 용접 시공순서는 여러 층으로 갈라서 용접을 실시하였다. 그 이유는 개선 내부를 한번에 채우는 경우 플럭스가 녹은 후 응고되었을 때 양단 개선면에 꽉 끼어 비드로부터의 슬래그 박리가 상당히 어려웠다. 이 경우 개선 내부와 표면까지의 용접을 1패스로 하지 않는 경우 용접을 갈라서 할 수밖에 없었다.After the CO 2 welding, SAW welding, which can be used for solid welding, is carried out. The welding sequence is divided into several layers for welding. The reason for this was that when the interior of the refinery was filled at once, the slag peeled off from the beads was very difficult because the flux melted and solidified on both sides of the improved side when solidified. In this case, if the welding to the inside and the surface of the improvement was not made in one pass, the welding had to be divided.

만약, 고전류로 한번에 채우고자 할 때 적정 전류 이하가 되거나 정도 문제로 갭이 어쩔 수 없이 갭이 넓어져 CO2 용접 비드부가 넓어지는 곳에서는 도 1의 (b)와 같이 개선표면까지 다 채우기가 어려울 뿐만 아니라 용접 아크가 CO2 용접부 양단을 녹이지 못하고 지나가 용입불량과 같은 결함으로 남을 가능성이 많아졌다. If, difficult to fill it to the improved surface, as becomes the gap is widened without gap is unavoidable to have an optimal current or approximately problem when you want to fill once a high current of a Figure 1, where that CO 2 welding bead portion wider (b) In addition, weld arcs could not melt at both ends of the CO 2 weld, leaving them more likely to remain defects such as poor penetration.

또한, 적정 갭 조건에서 고전류에 의해 용접하는 경우 도 1의 (c),(d)와 같이 먼저 용접된 CO2 용접 비드부가 녹아 이면 밖으로 용락되어 용접이 불가능하게 된다. 다시말해 1 ~ 2 비드까지의 CO2 용접에 의한 비드 높이를 10mm 이상 높게 하 지 못하는 경우 아크 열을 이기지 못하고 녹아 버리게 된다.In addition, when welding by a high current in an appropriate gap condition, as shown in Fig. 1 (c), (d), the first welded CO 2 weld bead is melted out of the back is not possible to weld. In other words, if the bead height by CO 2 welding from 1 to 2 beads cannot be increased by more than 10mm, the arc heat will not overcome and will melt.

따라서 기존에는 상기와 같이 SAW 용접 패스 수를 줄이고자 용접전류를 과다하게 사용할 때 높은 입열에 의해 이미 가접되어진 CO2용접 비드가 녹아 용강이 이면으로 새는 용략현상이 발생하였다. 또한, 초기 정도저하로 갭이 많이 발생할 때 CO2용접위로 SAW 용접을 할 경우 CO2 용접 양단에서의 용입불량이 발생하였다.Therefore, conventionally, when using too much welding current to reduce the number of SAW welding passes as described above, the molten steel leaks to the back side due to melting of CO 2 welding beads already welded by high heat input. In addition, when the SAW welding over CO 2 welding penetration is poor at both ends of the CO 2 welding was generated when the gap is caused by a lot of the initial degree of degradation.

이에, 본 발명은 상기한 문제점을 해결하기 위한 것으로서 본 발명의 목적은 SAW 용접 캐리지에 위빙 장치를 구성함으로써 와이어를 용접선 방향에 대하여 직교하여 좌우로 위빙할 수 있도록 하는 SAW 위빙 장치를 제공하는 데 있다.Accordingly, an object of the present invention is to provide a SAW weaving device which allows the wire to weave from side to side orthogonal to the welding line direction by configuring a weaving device in the SAW welding carriage. .

Consists of

이때, SAW 용접 캐리지의 구성은 도 3과 같이 주행 캐리지에 릴 타입의 와이 어(10kg ~ 40kg, 2.4Ø, 3.2Ø, 4.0Ø, 4.8Ø, 5.6Ø, 6.4Ø)를 걸 수 있는 드럼형 제어판넬(27)이 연결붐(33)에 연결되어 있다. 상기 연결붐(33)의 나머지 끝단에는 와이어 송급장치(19)와 용접노즐(21)이 연결되며, 상기 연결붐(33)은 용접선 맞춤슬라이드(17)에 연결되며 용접중 용접선 맞춤슬라이드(17)를 좌우 수동으로 움직여서 용접선과 와이어를 일치시켜 용접이 이루어질 수 있도록 구성하였다.At this time, the configuration of the SAW welding carriage is a drum-type control to hang the reel-type wire (10kg ~ 40kg, 2.4Ø, 3.2Ø, 4.0Ø, 4.8Ø, 5.6Ø, 6.4Ø) to the traveling carriage as shown in FIG. The panel 27 is connected to the connecting boom 33.

또한, 본 발명은 용접선 맞춤슬라이드(17)에 위빙 구동모터(31)를 달아 좌우 위빙을 시켜 주기에는 기반 하중이 커지고, 용접에 적정한 위빙 속도를 맞추기 위해서는 슬라이드의 구조가 많이 커지기 때문에 용접선맞춤 슬라이드(17)에 위빙 구동모터(31)를 달아 위빙장치를 구성하는 것은 무리가 따랐다.In addition, in the present invention, the base load increases when the weaving drive motor 31 is attached to the welding line alignment slide 17 and the weaving drive motor 31 is left and right weaved, and the structure of the slide increases so as to match the weaving speed suitable for welding. 17) attaching the weaving drive motor 31 to the configuration of the weaving device was too much.

따라서 본 발명에서는 연결붐(33)과 와이어 송급장치(19)를 분리하여 그 사이에 용접선 맞춤슬라이드(17)를 구성하여 상기와 같은 문제점을 해결하였다.Therefore, the present invention solves the above problems by separating the connecting boom 33 and the wire feeder 19 to form a welding line alignment slide 17 therebetween.

즉, 도 3과 같이 연결붐(33) 끝단에 슬라이드 바닥판(35)를 체결하고, 그 위로 양단에 스크류 축(39)을 연결하고, 상기 스크류 축(39)은 슬라이드 블록(37)의 나사산을 따라 위빙 구동모터(31)에 의해 직선 왕복 운동을 하게 된다.That is, as shown in FIG. 3, the slide bottom plate 35 is fastened to the end of the connecting boom 33, and the screw shaft 39 is connected to both ends thereof, and the screw shaft 39 is a thread of the slide block 37.

이러한 위빙 동작의 구성은 위빙 기구부(29)에 체결된 위빙 구동모터(31)의 위치 제어를 통하여 이루어지며, 위치 제어는 스테핑 모터와 전용 드라이버를 사용하여 정해진 펄스 입력 값에 따라 위빙 거리, 위빙 속도, 위빙 양단 정지시간 등을 마이컴 제어방식으로 설정할 수 있다.The configuration of the weaving operation is made through the position control of the weaving drive motor 31 fastened to the weaving mechanism unit 29, the position control is a weaving distance, weaving speed according to the pulse input value determined by using a stepping motor and a dedicated driver. , Weaving stop time can be set by the microcomputer control method.

이때, 위빙 양 끝단에 정지 시간을 0 ~ 2초까지 20등분하여 지정할 수 있으며, 위빙 폭의 20mm를 기준으로 위빙 속도를 120회/분 가능하도록 지정할 수 있다.At this time, the stop time can be specified by dividing the stop time into 20 equal parts from 0 to 2 seconds at both ends of the weaving, and can be specified to enable the weaving speed 120 times / minute based on 20 mm of the weaving width.

또한, 본 발명은 소형이면서도 고속 마이크로 컨트롤러를 사용하였으며, 내부 전원은 SAW 캐리지에서 제공하는 입력 전원인 AC 110V 전원을 사용하여 모터 구동 및 제어 전원으로 사용하는 DC 파워 스위칭 전원장치를 구성하였다. 또한 위빙 설정치는 도 4에 도시된 바와 같이 7-세그먼트 발광다이오드(LED)를 통해 확인할 수 있다.In addition, the present invention uses a compact, high-speed microcontroller, and the internal power source is configured with a DC power switching power supply using the AC 110V power source, the input power provided by the SAW carriage, as a motor driving and control power source. In addition, the weaving setting value can be confirmed through a 7-segment light emitting diode (LED) as shown in FIG. 4.

이상에서와 같이 본 발명에 의한 서브머지드아크용접 위빙장치에 따르면, 다음과 같은 효과가 있다.As described above, according to the submerged arc welding weaving device according to the present invention, the following effects are obtained.

첫째, 본 발명은 SAW 용접 캐리지에 위빙 장치를 구성함으로서 고전류에 의한 용접에서도 용락을 방지할 수 있어 여러 패스로 용접하는 것에 패스 수를 많이 줄일 수 있다.First, in the present invention, by forming a weaving device in the SAW welding carriage, it is possible to prevent melting even when welding by high current, so that the number of passes can be greatly reduced in welding in several passes.

둘째, 본 발명은 SAW 용접 캐리지에 위빙 장치를 구성함으로서 위빙없이 고전류 용접을 실시할 때 용융풀이 선행되어 아크가 CO2용접 비드를 충분히 녹여주지 못하여 CO2 비드 양단에서 녹지 않고 그대로 남아 결함으로 남는 용융불량과 같은 문제도 위빙을 하여 아크가 미치는 영역을 골고루 미치기 때문에 고전류에 의한 용 접에서 발생할 수 있는 용입불량 문제를 해결할 수 있다. Second, in the present invention, by forming the weaving device in the SAW welding carriage, when the high current welding is performed without weaving, the melting pool is preceded and the arc does not melt the CO 2 welding beads sufficiently, so that the melt does not melt at both ends of the CO 2 beads and remains as a defect. Weaving problems such as defects evenly spreads the arc-impacted area, which can solve the problem of poor penetration caused by high current welding.
