Description
본 고안은 피용접재(모재)를 편면 용접할 때-더욱 구체적으로는, 수평방향(횡방향)으로 용접할 때-상기 피용접재의 이면에 백-비드(back bead)가 균형있게 형성되도록 함과 동시에, 용접부에 언더컷과 오버랩이 생성되지 않도록 하는 용접지지구용 세라믹 타일에 관한 것이다.The present invention provides a balanced back-bead on the back surface of the welded material when welding the welded material (base material) on one side-more specifically, when welding in the horizontal direction (lateral direction). At the same time, the present invention relates to a ceramic tile for a welding support that prevents undercuts and overlaps from being generated in the weld zone.
도4는 종래 사용되던 세라믹 타일(1a)의 측면도이다.Fig. 4 is a side view of the ceramic tile 1a which is conventionally used.
상기 도면에서 참조되는 바와 같이, 종래의 세라믹 타일(1a)은, 상면의 중앙부분에, 오목한 홈 형상으로 슬래그 포켓(3)이 요설되어 있다.As referred to in the drawing, in the conventional ceramic tile 1a, the slag pocket 3 is recessed in a concave groove shape at the center of the upper surface.
그런데, 상기의 세라믹 타일(1a)은, 타일(플럭스)의 융점이 1350℃-1500℃ 사이에 있도록, SiO2-Al2O3-MgO계 고형 플럭스의 조성을 SiO2:45-70 중량%, Al2O3:15-40 중량%, MgO:5-30 중량%의 범위로 하고, 또한 SiO2-Al2O3-MgO의 합계도 90 중량% 이상으로 하며, 겉보기 기공율은 5-40%가 되도록 제조한 것이었기 때문에, φ1.4㎜ 이상의 용접와이어(5)를 이용하여 고전압 및 고전류 상태에서 수평자세로 용접을 실시하는 경우, 도5에 도시된 것처럼, 백-비드의 상부측에는 심각한 언더컷 현상이 발생되고, 상기 백-비드의 하부측에는 오버랩(15)이 생겨, 상기 백-비드의 상부측-즉, 언더컷(6)이 생성된 부위에 한번 더 보강용접을 실시한 다음 상기 오버랩 부위와 함께 그라인딩 수정작업을 해 주고 있는 실정이었다.By the way, is the melting point of the tile (flux) to be between 1350 ℃ -1500 ℃, SiO 2 -Al 2 O 3 -MgO -based composition of the solid flux SiO 2 ceramic tiles (1a) of the: 45-70% by weight, Al 2 O 3 : 15-40% by weight, MgO: 5-30% by weight, and the sum of SiO 2 -Al 2 O 3 -MgO is 90% by weight or more, and the apparent porosity is 5-40%. Since the welding wire 5 is welded at a diameter of 1.4 mm or more in the horizontal posture in the high voltage and high current state, as shown in FIG. 5, a severe undercut is formed on the upper side of the back-bead. Phenomenon occurs, and an overlap 15 is formed on the lower side of the back-bead, and the reinforcement welding is performed once more on the upper side of the back-bead, that is, the undercut 6 is formed, and then together with the overlapped portion. Grinding was corrected situation.
따라서, 종래 수평자세 용접은 비능률적(비효율적)이고 또한 비경제적인 단점이 있었다.Therefore, the conventional horizontal posture welding has disadvantages of being inefficient (inefficient) and also inefficient.
본 고안은 이러한 종래의 문제점을 개선하기 위해 안출된 것으로서, φ1.4㎜ 이상의 용접와이어(5)를 이용하여 수평자세로 용접을 하더라도, 피용접재인 철판 이면의 백-비드에 언더컷 현상과 오버랩이 생기지 않도록 함으로서, 효율적이고 경제적인 수평방향 용접이 가능하게 한 용접지지구용 세라믹 타일을 제공함에 목적이 있다.The present invention has been devised to improve such a conventional problem, and even when welding in a horizontal posture using a welding wire 5 of φ1.4 mm or more, undercut phenomenon and overlap on the back-bead of the back side of the steel plate to be welded are prevented. It is an object of the present invention to provide a ceramic tile for a welding support, which enables efficient and economical horizontal welding.

이하, 첨부된 도면을 참조하여, 본 고안에 따른 용접지지구용 세라믹 타일의 구성에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, it will be described in detail the configuration of the ceramic tile for welding support according to the present invention.
먼저, 본 고안의 용접지지구용 세라믹 타일은, 선출원 특허 제1999-27648호에 기재된 플럭스를 이용하여 제작됨을 밝혀둔다.First, it is noted that the ceramic tile for the welding support of the present invention is manufactured using the flux described in Japanese Patent Application No. 1999-27648.
도면중, 도2는 본 고안에 따른 용접지지구용 세라믹 타일의 측면도이다.2 is a side view of the ceramic tile for the welding support according to the present invention.
상기의 도면에서 참조되는 바와 같이, 본 고안의 세라믹 타일(1)은,As referred to in the above drawings, the ceramic tile 1 of the present invention,
상면의 양측 단부에 형성되는 수평방향의 숄더부(8,8a)와, 상기 숄더부중 일측 숄더부(8a)의 내측연에 잇달아서 형성되는 오목한 홈 형상의 슬래그-홈(13)과, 상기 숄더부중 타측 숄더부(8)의 내측연으로부터 상기 슬래그-홈(13)까지 3°∼20°의 각도로서 하향 경사지게 형성되는 경사면(9)과, 상기 경사면 위에 형성되는 중심선(16)과, 저면의 정중앙에 돌설되는 삼각형상의 인디케이터(7)로 구성됨을 특징으로 한다.Horizontal shoulder portions 8 and 8a formed at both end portions of the upper surface, concave groove-shaped slag grooves 13 successively formed at inner edges of one shoulder portion 8a of the shoulder portion, and the shoulder The inclined surface 9 is formed to be inclined downward from the inner edge of the other side shoulder portion 8 to the slag-groove 13 at an angle of 3 ° to 20 °, the center line 16 formed on the inclined surface, and the bottom surface. It is characterized by consisting of a triangular indicator (7) protruding in the center.
이와 같이 구성되는 본 고안의 세라믹 타일로 만든 편면용접용의 용접지지구가 도1에 개략적으로 도시되어 있다.The welding support for single-sided welding made of the ceramic tile of the present invention configured as described above is schematically shown in FIG.
상기의 도면에서 참조되는 바와 같이, 본 고안의 용접지지구는,As referenced in the above drawings, the welding support of the present invention,
상면 양측이 이형지(11)로 덮여 있고 가운데 부분은 접착층이 그대로 나출(裸出)되어 있는 테이프(10)상에, 본 고안의 세라믹 타일(1)을 일렬로 배열하여 구성되는데, 상기 세라믹 타일의 대향면-즉, 접합면(14)-은 곡면 형태로 되어 있어서, 인접한 대향면끼리 서로 밀접하게 접해 있다.Both sides of the upper surface are covered with a release paper 11 and the center portion is formed by arranging the ceramic tiles 1 of the present invention in a row on a tape 10 having an adhesive layer as it is. The opposing faces-that is, the joining faces 14-are curved, so that adjacent opposing faces are in close contact with each other.
첨부도면중 도3은, 상기와 같이 구성되는 본 고안의 용접지지구로 수평용접을 실시할 때의 작업상태를 나타낸 도면이다.Figure 3 of the accompanying drawings is a view showing a working state when performing horizontal welding with the welding support of the present invention configured as described above.
도면에서 보듯이, 먼저 일정 간격-예컨대 4∼10㎜의 간격-을 두고 2장의 피용접재(4)를 나란히 배열한 후, 상기 피용접재(4)의 저면에 본 고안의 용접지지구(2)를 부착한다.As shown in the figure, first, the two welded members 4 are arranged side by side at a predetermined interval, for example, 4-10 mm, and then the welding support of the present invention is formed on the bottom of the welded member 4 ( Attach 2).
이때, 상기 용접지지구(2)의 상면 일측에 치우쳐서 형성된 슬래그-홈(13)이 위쪽에 놓인 피용접재(4)의 저면부분에 위치되도록, 또한 저면측의 인디케이터(7)가 피용접재 사이의 정중앙부에 놓이도록, 중심선(16)에서 똑같은 간격을 두고 부착해야 한다.At this time, the slag-groove 13 formed by being biased to one side of the upper surface of the welding support 2 is located on the bottom portion of the welded member 4 placed on the upper side, and the indicator 7 on the bottom side of the welded member It should be attached at equal intervals on the centerline 16 so that it lies in the center of the center.
이와 같은 상태에서 수평방향으로 용접을 하면, 본 고안의 세라믹 타일을 구성하고 있는 플럭스가 필요한 양만큼만 용융되어, 피용접재의 저면에 백-비드를 형성하게 된다.When welding in this state in the horizontal direction, the flux constituting the ceramic tile of the present invention is melted only as much as necessary, to form a back-bead on the bottom of the material to be welded.
이때, 본 고안의 세라믹 타일(1)에 형성되어 있는 경사면(9)은, 용융플럭스가 아래로 흐르는 것을 방지함으로서 피용접재(4) 사이의 용접부(12)에는 오버랩(15)이 생기지 않는다.At this time, the inclined surface 9 formed on the ceramic tile 1 of the present invention prevents the molten flux from flowing downward so that the overlap 15 is not formed in the welded portion 12 between the welded materials 4.
또한, 경사면(9)과 피용접재(4) 사이의 공간을 채우고도 남은 과량의 용융물은 점점 위쪽으로 차오르게 되는데, 주지된 바와 같이, 용융물(금속)의 비중이 슬래그(플럭스)보다 무겁기 때문에, 용융된 플럭스가 슬래그-홈(13) 안으로 밀려 올라가서 모이게 된다.In addition, the excess melt remaining after filling the space between the inclined surface 9 and the welded material 4 gradually rises upward. As is well known, the specific gravity of the melt (metal) is heavier than the slag (flux). The molten flux is pushed into the slag groove 13 and collected.
이러한 이유로, 본 고안의 용접지지구로 편면용접을 하면, 용접부(12)에 언더컷(6)이 생성되지 않게 된다.For this reason, when the one-side welding with the welding support of the present invention, the undercut 6 is not generated in the weld portion 12.
이상과 같이, 본 고안의 용접지지구용 세라믹 타일(1)에 의하면, 효율적이면서도 경제적으로 수평 용접을 할 수 있다는 장점이 있다.As described above, according to the ceramic tile 1 for welding support of the present invention, there is an advantage that horizontal welding can be efficiently and economically performed.
또한, 본 고안에 따르면, 용접부(12)에 언더컷(6)과 오버랩(15)이 생성되지 않기 때문에, 용접부의 품질이 우수한 장점이 있다.In addition, according to the present invention, since the undercut 6 and the overlap 15 are not generated in the welded portion 12, there is an advantage of excellent quality of the welded portion.
