Description

용접 지지구{SUPPORTER FOR WELDING WORK}Welding Supports {SUPPORTER FOR WELDING WORK}

본 고안은 용접 지지구에 관한 것으로서, 더욱 구체적으로는, 대형의 탱크나 선체(hull)의 제작시, 두꺼운 금속판(厚板: 모재)을 싱글패스로 용접하는데 이용하는 세라믹 재질의 용접 지지구에 관한 것이다.The present invention relates to a welding support, and more particularly, to a welding support made of a ceramic material used to weld a thick metal plate in a single pass when producing a large tank or hull. will be.

통상적으로, 두꺼운 금속판을 이용하여 대형의 탱크나 선체를 건조(建造)하는 경우, 이들 금속판의 연부를 따라 용접작업을 실시하게 된다.Usually, when a large tank or hull is built using a thick metal plate, welding is performed along the edges of these metal plates.

이때, 용접 표면으로부터 루트(root)까지, 용융 용접제를 완전히 침투시켜 용접 이음매를 형성하는 것이 바람직하다.At this time, it is preferable to completely penetrate the molten welding agent from the weld surface to the root to form a weld seam.

그런데, 종래에는 이러한 용접 이음매의 형성시, 용접의 대상이 되는 모재(母材)의 양면을 용접하는 멀티패스(MULTI-PASS) 용접방식으로 작업을 수행하였기 때문에, 비용과 시간의 소비가 크다는 단점이 있었다.However, in the past, when the welding seam is formed, the work is performed by a multi-pass welding method in which both surfaces of the base material to be welded are welded. There was this.

이러한 단점을 개선하기 위해, 모재(母材)의 이면 중앙에, 세라믹 재질의 용접 지지구를 위치시켜, 용융된 용융 용접재가 이면 측에도 보유되도록 하는 싱글패스(SINGLE-PASS) 용접법이 최근 개발되었는데, 이때 사용되는 용접 지지구는, 도1에 도시된 본 고안의 용접 지지구와 마찬가지로, 호형(弧形)의 채널이 형성되어 있는 용접 타일의 이면측에, 두께 70미크론 이상의 알루미늄 접착 테이프를 부착한 것을 사용하였다.In order to alleviate this drawback, a single-pass welding method has been recently developed in which a welding support made of ceramic is placed at the center of the back surface of the base material so that the molten molten weld material is also retained at the back side. As the welding support used at this time, like the welding support of the present invention shown in Fig. 1, the one having the aluminum adhesive tape having a thickness of 70 microns or more is attached to the back side of the welding tile in which the arc-shaped channel is formed. It was.

그러나, 이 용접 지지구는 CO2가스, Ar가스 등을 보호가스로 사용하여 용접할 때, 상기 접착 테이프의 내화본드가 용접열에 의해 강한 접착력을 발휘해야 함에도 불구하고, 상기 접착 테이프의 두께가 두꺼운 관계로, 피용접물인 두꺼운 금속판(母財)과 접착이 잘 되지 않는 단점이 있었다.However, this welding support has a high thickness of the adhesive tape, despite the fact that the fireproof bond of the adhesive tape must exert a strong adhesive force by the heat of welding when welding using CO 2 gas, Ar gas, or the like as a protective gas. As a result, there was a disadvantage that the adhesion with the thick metal plate (母 財) to be welded is not good.

특히, 겨울철에는 모재의 표면온도가 더욱 낮아 접착력은 더욱 더 감소하게 되고, 이 때문에 용접후 피용접물의 이음매 뒷부분(BACK BEAD)의 높이가 고르지 못한 단점이 있었다.In particular, in winter, the surface temperature of the base material is lower, and thus the adhesive force is further reduced, and thus, there is a disadvantage in that the height of the back portion of the welded object after welding is uneven.

또한, 두꺼운 접착 테이프를 사용함으로서, 경제적인 면에서도 가격의 상승을 초래하여 용접비용을 높이는 문제가 있었으며, 1회용으로 사용되는 용접 지지구의 특성상, 자원을 낭비하는 면도 없지 않았다.In addition, by using a thick adhesive tape, there was a problem in the economical aspect caused a rise in the price, thereby increasing the welding cost, and was not a waste of resources due to the characteristics of the welding support used for single use.

본 고안은 이러한 종래의 용접 지지구가 갖고 있던 문제점을 개선하기 위해 안출된 것으로서, 접착 테이프와 모재 사이의 접착력을 향상하고, 경제적인 측면과 자원절약적인 측면에서 우수하며, 특히 용접후 형성되는 백 비드의 높이를 균일하게 할 수 있는 용접 지지구를 제공함에 목적이 있다.The present invention was devised to improve the problems of the conventional welding support, improves the adhesive force between the adhesive tape and the base material, and in terms of economical and resource-saving, particularly the bag formed after welding It is an object of the present invention to provide a welding support capable of making the height of the beads uniform.

본 고안에서는 이러한 목적을 달성하기 위해, 세라믹 재질의 용접 타일에 부착시키는 접착 테이프의 두께를 20∼65 미크론으로 제한하며, 그 폭도 130∼200㎜의 범위 내로 제한한다.In the present invention, in order to achieve this purpose, the thickness of the adhesive tape attached to the ceramic welding tile is limited to 20 to 65 microns, and the width thereof is also limited to the range of 130 to 200 mm.

이하, 첨부된 도면을 참조하여, 본 고안에 따른 용접 지지구의 구성에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, it will be described in detail the configuration of the welding support according to the present invention.

도1은 본 고안에 따른 용접 지지구의 개략적인 사시도이다.1 is a schematic perspective view of a welding support according to the present invention.

상기 도면에서 참조되는 바와 같이, 본 고안의 용접 지지구(1)는,As referenced in the drawings, the welding support 1 of the present invention,

중앙에 용융 채널(5)이 형성되어 있는 용접 타일(2)의 이면측에, 두께가 20∼65 미크론이고 폭이 130∼200㎜인 알루미늄 재질의 접착 테이프(3)를 부착하여 구성함을 특징으로 한다.An aluminum adhesive tape 3 having a thickness of 20 to 65 microns and a width of 130 to 200 mm is attached to the back side of the welding tile 2 having the melt channel 5 formed in the center thereof. It is done.

이어서, 본 고안에 따라 제작되는 용접 지지구의 작용에 대해, 도2를 참조하여 설명한다.Next, the operation of the welding support produced according to the present invention will be described with reference to FIG.

도면에서 참조되듯이, 본 고안에 따라 제작된 용접 지지구(1)의 이형지(4)를 벗겨낸 상태에서, 용접해야 할 모재(6) 사이를 약간 띄워, 그 빈틈이 용접 타일(2)의 중앙에 형성되어 있는 용융 채널(5)의 중심선상에 위치되게 한 다음, 모재(6)의 상면측에서 용접재를 용융시킨다.As referenced in the drawings, in the state where the release paper 4 of the welding support 1 produced according to the present invention is peeled off, the space between the base material 6 to be welded is slightly lifted, so that the gap of the welding tile 2 After being placed on the center line of the melt channel 5 formed in the center, the welding material is melted on the upper surface side of the base material 6.

이와 같이 하면, 모재(6) 사이의 간격을 통해, 상기 모재(6)의 상면에서 하면으로, 용융 용접재가 흘러내리게 되고, 따라서 모재(6)의 양면에서 거의 동시에 비드(BEAD)가 형성되어 용접된다.In this case, the molten welding material flows down from the upper surface of the base material 6 to the lower surface through the gap between the base materials 6, so that beads BEAD are formed and welded on both sides of the base material 6 at about the same time. do.

그런데, 본 고안의 용접 지지구처럼, 접착 테이프(3)의 두께가 얇은 경우에는, 내화본드가 도포되어 있는 접착 테이프의 거동이 종래보다 더 부드러워진다.By the way, like the welding support of this invention, when the thickness of the adhesive tape 3 is thin, the behavior of the adhesive tape with which the fireproof bond is apply | coated becomes smoother than before.

따라서, 알루미늄 박막의 특성이 살아나서 접찹력이 강해지게 되며, 용접열이 지난 직후, 모재에 강하게 달라붙게 된다.Therefore, the properties of the aluminum thin film is enhanced, the adhesive force is strong, and immediately after the heat of welding, it is strongly adhered to the base material.

이로 인해, 종래보다 접착 테이프의 접착성 및 효율성이 우수해진다.For this reason, the adhesiveness and efficiency of an adhesive tape become excellent compared with the past.

또한, 경제적인 측면에서 볼 때, 두께가 두꺼운 종래 접착 테이프의 생산비용보다 두께가 얇은 본 고안의 접착 테이프의 생산비용이 20∼50% 정도 절감되는 장점이 있었다.In addition, from an economical point of view, there was an advantage in that the production cost of the adhesive tape of the present invention, which is thinner than the production cost of the conventional thick adhesive tape, was reduced by about 20 to 50%.

또한, 얇은 두께의 접착 테이프를 사용하면, 모재(6)에 더욱더 잘 부착되므로 용접시 생성되는 백 비드의 높이를 균일하게 할 수 있다는 장점이 있다.In addition, the use of a thin adhesive tape has an advantage that the height of the back bead generated during welding can be made uniform because it is more easily attached to the base material 6.

또한, 1회용으로 사용되는 용접 지지구의 접착 테이프 두께를 얇게 함으로서, 20∼50% 정도, 자원을 절약하는 효과가 있다.Further, by reducing the thickness of the adhesive tape of the welding support used for single use, there is an effect of saving resources by about 20 to 50%.

또한, 종래의 용접 지지구는, 접착 테이프의 폭이 130㎜ 이하였기 때문에, 반자동 또는 자동용접시, 고온의 열에 의해 접착 테이프가 모재(6)로부터 떨어지게 되는 문제점이 있어 접착 테이프의 이면에 마그네트 등의 자성체를 보강하는 등의 번거로운 작업이 필요하였으나, 본 고안의 경우에는, 그럴 필요가 전혀 없어 경제적으로나 시간적으로 또 인력면에서 큰 절감을 이룰 수 있다는 장점이 있었다.In addition, in the conventional welding support, since the width of the adhesive tape is 130 mm or less, there is a problem that the adhesive tape is separated from the base material 6 by high temperature heat during semi-automatic or automatic welding. The cumbersome work such as reinforcing the magnetic material was required, but in the case of the present invention, there is no need to do so, and thus, there is an advantage in that it can be economically and timely and in terms of manpower.

이상과 같이, 본 고안의 용접 지지구에 의하면, 접착 테이프(3)와 모재(6) 사이의 접착력이 향상되는 장점이 있고, 경제적인 측면과 자원 절약적인 측면에서 우수하며, 특히 용접후 형성되는 백 비드의 높이가 균일하게 되어 용접 품질을 향상할 수 있다는 이점이 있다.As described above, according to the welding support of the present invention, there is an advantage that the adhesive force between the adhesive tape 3 and the base material 6 is improved, and in terms of economical and resource saving, it is particularly formed after welding There is an advantage that the height of the back bead is uniform to improve the welding quality.
