본 고안은 금속의 용접시 제1층 비이드 용접에서의 확실한 이파를 만들수 있는 이파용접법(裏波熔接法)의 한방법으로 사용되는 백킹(Backing)에 관한 것으로 특히 두께 20mm이상의 후판용접시 그 K형홈 또는 X형홈 용접에 적합한 원형백킹의 개량형이다.The present invention relates to the backing used as a method of wave welding method, which can make sure wave in the first layer bead welding during metal welding. It is an improved version of the circular backing suitable for welding the groove or X groove.

백킹을 덧대어 용접하는 이파용접은 표면용접과 동시에 이파를 직접 형성하여 그 이면 가우징 및 이면용접을 생략할수 있는 편면 용접기법으로써 좋은 방법이 아닐수 없다.The wave welding method by welding the backing is a one-sided welding technique that can form the wave directly at the same time as the surface welding and omit the back gouging and the back welding.

그래서 20mm 이상의 후판을 맞대기용접이음할때의 X형 또는 K형 홈에도 백킹을 사용하였던 것이다.Therefore, the backing was also used for X- or K-shaped grooves when butt welded joints of 20 mm or more.

백킹은 용접부위의 홈에 따라 여러 가지 형태를 가지며 X형홈 또는 K형홈용접(완전용입)용 백킹으로서는 주로 원형백킹이 사용되어진다.The backing has various forms depending on the groove of the welded area. As the backing for X-type groove or K-type groove welding (complete injection), mainly circular backing is used.

그러나 종래의 원형백킹은 글자그대로 주면이 원형으로된 기둥 모양이어서 큰 문제점을 안고 있는 것이다.However, the conventional circular backing is a columnar shape of the main surface as it is literally has a big problem.

그 이유로서는 먼저 제1도와 같이 두 금속(M1)(M2)을 본용접(本熔接)하기에 앞서 잠정적으로 고정시키기 위해 용접부(A)를 따라 군데군데 짧은 용접을 하게 되는 가용접(假熔接)을 행할때 제3도(c)와 같이 그 가용접부(TW)이면으로 흐른 용접물(B) 때문에 백킹(BK)의 밀착상태가 좋지 못하므로 이면 비이드의 오버랩이나 언더 컷등 용접 결합이 발생하여 현재는 거의 사용하지 않고 있는 실정이다.For this reason, as shown in FIG. 1, prior to main welding of the two metals M1 and M2, temporary welding is performed in several places along the welding portion A in order to temporarily fix the two metals M1 and M2. As shown in Fig. 3 (c), due to the weld (B) flowing to the backside of the weldable part (TW), the adhesion state of the backing (BK) is not good. Is rarely used.

결국 이와 같은 문제점 때문에 백킹에 의한 이파용접법을 실시하지 못하고 원시적인 방법으로 하여야 하므로 이면 가우징 및 이면용접등 시간과 공수가 많이 들었던 것이다.Eventually, because of this problem, the back wave welding method cannot be carried out by the primitive method.

본 고안은 위와 같은 문제점을 제거할 목적에서 안출한 것으로서 단순한 원형기둥이 아니고 원주에 소정의 폭으로 호형의 홈(Groove)을 형성하여 가용접작업을 수용할수 있는 X/K형 용접용 백킹을 실현시키고자 하는 바 첨부된 제2도와 제3도(a)(b)에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised to eliminate the above problems, and is not a simple circular column, but realizes an X / K-type welding backing that can accommodate the welding process by forming a groove of a certain width in a circumference. When described in detail with reference to the attached 2 and 3 (a) (b) as follows.

본 고안 백킹재는 제2도에 보인 바와 같이 대체로 원기형인 몸체(1)의 주면(2)일측부에 소정의 폭(W)을 갖는 호형홈(3)이 길이 방향을 따라 형성되고, 호형홈(3)의 면중심에는 길이방향으로 중심선(4)이 그어진 것으로서 이러한 백킹재 다수기가 일렬로 연속배치되고 그들 중심선(4)의 정반대편의 주면(2)부위에 넓은 금속접착 테이프(5)가 붙여진채 백킹으로서 사용된다.The backing material of the present invention has an arc-shaped groove 3 having a predetermined width W on one side of the main surface 2 of the generally cylindrical body 1, which is formed along the longitudinal direction, as shown in FIG. At the center of the plane of (3), a center line (4) is drawn in the longitudinal direction, and a plurality of such backing materials are continuously arranged in a row, and a wide metal adhesive tape (5) is attached to the main surface (2) of the opposite side of the center line (4). Used as a backing.

미설명 부호 6은 접착테이프의 박리지이다.Reference numeral 6 is a release paper of the adhesive tape.

이와 같은 본 고안 백킹을 사용함에 있어서는 제3도 (a) 및 (b)와 같이 두꺼운 두 금속(M1) (M2)을 맞대어 그 X형홈(Gx) 또는 K형홈(Gk)용접부(A) 군데군데에 제1도와 같이 가용접 한후에 상기 본 고안에 의한 백킹을 붙이되 호형홈(3)면에 표시된 중심선(4)을 용접부(A)중심에다 맞추어 놓음으로써 다음의 본용접을 행하면 된다.In using the present invention backing, as shown in FIGS. 3A and 3B, two thick metals M1 and M2 face each other, and the X-shaped groove Gx or K-shaped groove Gk is welded (A). After welding as shown in FIG. 1, the backing according to the present invention may be pasted, and the following main welding may be performed by aligning the center line 4 displayed on the arc-shaped groove 3 surface with the center of the welding portion A. FIG.

이때 가용접에 의한 용착금속이면의 용접물(B)은 몸체(1) 주면에 형성된 호형홈(3) 부위로 수용되므로 백킹몸체(1) 밀착상태가 전체적으로 양호하게 밀착된다.At this time, the weld B on the back surface of the weld metal by the welding is accommodated in the arc-shaped groove 3 formed on the main surface of the body 1, so that the backing body 1 is in close contact with the overall body.

이 호형홈(3)의 폭(W)은 맞대어진 두금속(M1)(M2)의 X형홈(Gx) 또는 K 형홈(Gk)의 각도와 몸체(1)의 지경을 감안하여 결정되고 그럼으로써 다른 불안정한 틈새는 허용되지 않는다.The width W of this arc-shaped groove 3 is determined in consideration of the angle of the body 1 and the angle of the X-shaped groove Gx or K-shaped groove Gk of the butted bimetallic M1 and M2. No other unstable gap is allowed.

그러므로 다음의 본 용점을 행할때 이면 비이드의 오버랩이나 언더컷등 용접 결합이 발생하지 않게 되고 한쪽 용접후 다른쪽의 용접 작업도 원활한 것이다.Therefore, when performing the following main points, the welding joint such as the overlap of the bead or the undercut does not occur, and the welding work on the other side after the one welding is also smooth.

이상에서 설명한 바와 같이 본 고안 백킹재는 규격화한 호형홈에 따라 호환성이 증대되는 효과가 기대됨과 아울러 용접작업후 그 이면 비이드의 외관 결합을 현저히 줄일수 있는 것이며 특히, 두꺼운 금속의 X형홈 또는 K형 홈용접을 자주 행하게 되는 조선 업체등에 작업시간 단축, 공수절감등을 가할 수 있는 유용한 고안이다.As described above, the backing material of the present invention is expected to have an effect of increasing compatibility according to the standard arc shape groove, and can significantly reduce the appearance coupling of the backside beads after welding work. It is a useful design that can shorten the working time and reduce the labor time for shipbuilding companies that frequently perform home welding.
