Description

용접용 표준 각장 시편{STANDARD SAMPLER OF WELDING BEAD WIDTH FOR WELDING}STANDARD SAMPLER OF WELDING BEAD WIDTH FOR WELDING}

본 발명은 용접용 표준 각장 시편에 관한 것으로, 보다 상세하게는 용접 각장의 불균일로 인하여 용접 각변형이 발생되는 것을 최소화시킬 수 있도록 용접 현장에서 용접시 실시간으로 비교 판단할 수 있는 표준 각장 시편을 제공하여 용접 품질을 높일 수 있도록 한 용접용 표준 각장 시편에 관한 것이다.The present invention relates to a standard rectangular specimen for welding, and more particularly, to provide a standard rectangular specimen that can be compared in real time when welding at the welding site in order to minimize the generation of weld angular deformation due to the non-uniformity of the weld angle. It relates to standard rectangular specimens for welding to improve weld quality.

일반적으로, 중장비, 교량, 건축빔, 선박, 해양구조물, 중?후판 플랜트 장비 등은 물론 선박 건조시 대부분의 작업은 용접작업이 기본적으로 발생하게 되며, 이러한 용접작업이 된 용접부의 검사 또한 당연히 병행하여 진행된다.In general, most of the work during construction of the ship, as well as heavy equipment, bridges, building beams, ships, offshore structures, heavy and heavy plate plant equipment, etc., and the welding work occurs basically, and of course the inspection of the welded weld is also parallel Proceed.

그러므로, 용접작업에 대한 결과의 신뢰도 또한 상당히 중요한 부분을 차지하게 된다.Therefore, the reliability of the results for the welding operation is also very important.

만일, 용접부의 상태가 양호하지 않다면 치명적인 결점이 발생하여 대형 사고로 발전할 수 있다.If the weld is not in good condition, a fatal flaw may occur and develop into a large accident.

그럼에도 불구하고, 종래에는 용접부를 검사하는데 있어 단지 숙련된 작업자의 육안에 의지하는 것이 보통이었다.Nevertheless, conventionally it was common to rely only on the naked eye of a skilled worker in inspecting welds.

특히, 도 1의 (a),(b)에 도시된 바와 같이, 제1모재(10)와 제2모재(20)를 서로 직각으로 배치하여 용접하는 필렛 용접의 경우, 용접비드(30)의 폭, 즉 각장(D1,D2)이 일정하게 유지되어야 하는데, 작업자에 따라 (a)처럼 각장(D1)이 표준보다 더 커지거나 혹은 (b)처럼 각장(D2)이 표준보다 작아지게 되면 용접 불량을 초래하게 된다.In particular, as shown in (a) and (b) of FIG. 1, in the case of fillet welding in which the first base material 10 and the second base material 20 are disposed at right angles to each other and welded, The width, ie, the lengths D1 and D2, should be kept constant, depending on the operator, if the length D1 becomes larger than the standard (a) or the length D2 becomes smaller than the standard (b), welding failure Will result.

더구나, 이와 같은 필렛용접은 선박 건조에 필요한 거의 전공정, 이를 테면 소조립부, 판넬조립부, 대조립부, 중조립부, 건조부, 가공부, 판넬부, 용연공장부 등 대부분의 공정에서 다량으로 이루어지기 때문에 표준에 맞는 용접비드(30)를 형성하는 것은 매우 중요하다.Moreover, such fillet welding is carried out in large quantities in most processes, such as small assembly, panel assembly, counterpart, heavy assembly, drying part, processing part, panel part, and yeonyeon plant part. It is very important to form a weld bead 30 in accordance with the standard because it is made.

이러한 중요성 때문에 최근에는 CCD카메라를 이용하여 용접비드를 촬상하고, 이를 판독하여 용접상태를 확인하는 예가 있지만, 이는 고가일 뿐만 아니라 매 작업시마다 일일이 촬상하고 판독한다는 것은 매우 번거로운 일이며, 작업중에 즉시 확인이 가능해야 하지만 사실상 이와 같은 부분을 쉽고 용이하게 충족시킬 수 없어 우수한 기술임에도 불구하고, 용접부의 형상이나 구조, 용접품질(내부조직) 등을 판독하는데는 용이하지만 필렛 용접시 각장 검사 부분에 대해서는 활용되지 못하고 있다.Because of this importance, recently, the welding bead is photographed using a CCD camera and the welding is read to confirm the welding state. However, it is not only expensive but it is very cumbersome to capture and read every single operation. Although it should be possible, it is easy to read the shape, structure, weld quality (internal structure) of welded part, but it is used for the inspection part of fillet welding, although it is an excellent technology because it cannot be easily and easily satisfied. I can't.

본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 선박 건조시 거의 전공정에서 이루어지고 있는 용접작업의 용접비드 형성을 위한 표준 시편을 제공하되, 휴대가 간편하게 하여 현장에서 즉시에 비교 확인할 수 있도록 하여 특히 각장 품질을 높임으로써 전체적인 용접 품위를 향상시킬 수 있도록 한 용접용 표준 각장 시편을 제공함에 그 주된 목적이 있다.The present invention was created in view of the above-mentioned problems in the prior art as described above, and provides a standard specimen for forming the weld bead of the welding work that is almost done in the entire process during ship construction, while being easy to carry Its main purpose is to provide standard rectangular specimens for welding that enable immediate comparison at the site and, in particular, improve the overall weld quality by increasing the quality of the sheet.

본 발명은 상기한 목적을 달성하기 위한 수단으로, 판상의 수평부재; 수평부재의 상면에 수직하게 접합된 수직부재; 수평부재와 수직부재가 만나는 양측 경계선을 따라 각장별로 형성된 용접비드;로 구성된 것을 특징으로 하는 용접용 표준 각장 시편을 제공한다.The present invention is a means for achieving the above object, a horizontal plate-like member; A vertical member bonded vertically to an upper surface of the horizontal member; It provides a standard rectangular specimen for welding, characterized in that consisting of; weld bead for each chapter along the boundary line between the horizontal member and the vertical member meet.

이때, 상기 수직부재의 일측면에는 각장의 크기(길이)를 표시하는 표시부가 더 형성된 것에도 그 특징이 있다.At this time, one side surface of the vertical member is characterized in that the display portion for displaying the size (length) of each sheet is further formed.

또한, 상기 수평부재와 수직부재는 흰색의 아크릴로 제조되고, 상기 용접비드는 검정색의 실리콘으로 형성된 것에도 그 특징이 있다.In addition, the horizontal member and the vertical member is made of white acrylic, the weld bead is also characterized by being formed of black silicon.

뿐만 아니라, 상기 수평부재와 수직부재는 서로 동일한 크기를 갖고, 전체 형상이 'ㄴ' 형태가 되게 접합된 것에도 그 특징이 있다.In addition, the horizontal member and the vertical member has the same size with each other, the overall shape is characterized in that the bonded to form a 'b' shape.

본 발명에 따르면, 필렛 용접시 각장의 용접비드 형상을 일정하고 균일하게 할 수 있도록 표준 시편과 항상 비교하면서 용접할 수 있어 용접 품질이 향상되고 용접 불량이 줄어드는 효과를 얻을 수 있다.According to the present invention, the weld bead can be welded at all times compared to standard specimens so that the weld bead shape of each sheet can be uniformly and uniformly during the fillet welding, thereby improving the welding quality and reducing the welding defect.

Figure 3 is an exemplary view showing another modified example of the standard rectangular specimen for welding in accordance with the present invention.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

먼저, 도 2는 본 발명에 따른 용접용 표준 각장 시편을 보인 예시도이다.First, Figure 2 is an exemplary view showing a standard rectangular specimen for welding in accordance with the present invention.

도 2에 도시된 바와 같이, 본 발명에 따른 용접용 표준 각장 시편은 필렛 용접시 활용될 수 있도록 수직하게 연결된 두 개의 부재를 포함한다.As shown in Figure 2, the standard rectangular specimen for welding according to the present invention comprises two vertically connected members to be utilized in fillet welding.

즉, 본 발명에 따른 용접용 표준 각장 시편은 휴대하기 용이하도록 작은 크기, 바람직하기로는 후술하는 바와 같이 손바닥 정도의 크기가 좋다.That is, the standard rectangular specimen for welding in accordance with the present invention is small in size for easy portability, and preferably, the size of a palm as described below.

본 발명에 따른 용접용 표준 각장 시편을 구성하기 위해 두 개의 부재가 포함되는데, 이 두 개의 부재는 각각 수평부재(100)와 수직부재(200)이다.Two members are included to construct a standard rectangular specimen for welding according to the present invention, which is a horizontal member 100 and a vertical member 200, respectively.

이때, 상기 수직부재(200)는 상기 수평부재(100)의 일측면, 즉 상면에 수직하게 고정되며, 상기 수평부재(100)의 폭 중앙에 배치됨이 바람직하다.At this time, the vertical member 200 is fixed to one side, that is, the upper surface of the horizontal member 100 vertically, preferably disposed in the center of the width of the horizontal member (100).

이를 테면, 도 2의 도시와 같이 대략 'ㅗ' 형상을 이루도록 함이 바람직하다.For example, it is preferable to form a substantially '대략' shape as shown in FIG.

그리고, 상기 수평부재(100)와 수직부재(200)의 양측 경계선을 따라 일정형상, 바람직하기로는 이등변삼각형 형태의 비드형상(300)을 형성한다.In addition, a bead shape 300 having a predetermined shape, preferably an isosceles triangle shape, is formed along both boundary lines of the horizontal member 100 and the vertical member 200.

여기에서, 본 발명에 따른 수평부재(100)와 수직부재(200)는 가볍고 휴대하기 편하며 색상 대비가 쉽도록 하얀색의 아크릴로 제조됨이 바람직하다.Here, the horizontal member 100 and the vertical member 200 according to the present invention is preferably made of white acrylic so as to be light, easy to carry, and easy color contrast.

또한, 상기 비드형상(300)은 용접비드와 대비하기 위한 표준 형상으로서 색상을 갖는 것이 좋은데, 이를 테면 검정색이 바람직하다.In addition, the bead shape 300 is preferably to have a color as a standard shape to contrast with the weld bead, such as black is preferred.

특히, 상기 비드형상(300)은 실리콘으로 접착 형성될 수 있다.In particular, the bead shape 300 may be adhesively formed of silicon.

아울러, 상기 비드형상(300)의 각장(D)은 용접 대상인 모재의 두께, 사용처 등과 같은 여러가지 요건에 따라 표준이 다를 수 있으므로 표준에 따라 다수개 형성할 수 있다.In addition, since the standard (D) of the bead shape 300 may vary depending on various requirements such as the thickness of the base material to be welded, where it is used, and the like, a plurality of beads may be formed according to the standard.

예컨대, 소조립부, 판넬조립부, 대조립부, 중조립부, 건조부, 가공부, 판넬부, 용연공장부 등 대부분의 공정에서 이루어지는 용접작업, 특히 필렛 용접작업시 여러 길이의 각장(D)이 요구되는데, 주로 이용되는 각장(D)의 길이는 4.5mm, 5.0mm, 5,5mm, 6.0mm 이다.For example, various lengths (D) of the welding work performed in most processes, such as small assembly, panel assembly, counterpart, heavy assembly, drying part, processing part, panel part, Yongyeon factory part, in particular fillet welding job Required, the lengths of the squares (D) which are mainly used are 4.5mm, 5.0mm, 5,5mm and 6.0mm.

물론, 이 이외에도 더 다양한 길이의 각장(D)을 갖는 각장 표준 시편을 만들 수 있으나, 각 각장(D) 별로 다량이 필요하므로 상기 4가지 길이를 기본형으로 제조할 수 있다.Of course, in addition to this can be made of a standard standard specimen of each sheet having a different length of the length (D), each of the length (D) is required because a large amount can be produced in the four types of the basic type.

덧붙여, 선박 건조공정 중 적어도 상기 4가지 길이의 기본형을 필요로 하는 개수를 실예로 소개하자면, 소조립부에서는 50세트, 판넬조립부에서는 17세트, 대조립부에서는 75세트, 중조립부에서는 20세트, 건조부(1부,2부,3부)에서는 합계 54세트, 가공부에서는 10세트, 판넬부에서는 13세트, 용연공장부에서는 45세트 등 사실상 대단히 많은 양을 필요로 한다.In addition, in the ship construction process, the number requiring the basic type of at least the above four lengths is exemplified as 50 sets in the small assembly section, 17 sets in the panel assembly section, 75 sets in the control assembly section, and 20 sets in the middle assembly section. In total, 54 sets of drying parts (1 part, 2 parts, 3 parts), 10 sets in the processing part, 13 sets in the panel part, and 45 sets in the Yongyeon plant part are required.

아울러, 상기 수지부재(200)의 일측면 중앙에는 표시부(400)를 두어 각장(D)의 길이를 표시해 둠으로써 작업자가 필요한 표준이 되는 각장(D)을 길이별로 쉽게 식별할 수 있도록 하면 더욱 좋다.In addition, by placing the display unit 400 at the center of one side of the resin member 200 to display the length of the length (D), it is more preferable that the operator can easily identify the length (D) to be the standard required by length. .

나아가, 본 발명 실시예에 따르면, 상기 수평부재(100)는 75 mm × 100 mm의 크기를 갖도록 하고, 상기 수직부재(200)는 50 mm × 100 mm의 크기를 갖도록 함이 휴대 보관에 가장 적당하며, 비교시 사용하기도 편리하다.Furthermore, according to the embodiment of the present invention, the horizontal member 100 has a size of 75 mm × 100 mm, the vertical member 200 has a size of 50 mm × 100 mm is most suitable for portable storage It is also convenient for comparison.

다른 예로, 본 발명에 따른 표준 시편을 도 3과 같은 형태로 변형시킬 수 있다.As another example, the standard specimen according to the present invention may be modified into a shape as shown in FIG. 3.

도 3의 예에서는 수평부재(100')와 수직부재(200')가 동일한 크기로 형성되며, 이들 두 부재가 서로 연결되어 일체를 이루도록 구성된다.In the example of FIG. 3, the horizontal member 100 ′ and the vertical member 200 ′ are formed in the same size, and the two members are connected to each other to form a single body.

이때, 상기 수평부재(100')와 수직부재(200')는 서로 별체로 구비된 다음 상호 결합 또는 접합되어 'ㄴ' 형상을 갖는 하나의 시편으로 제조될 수도 있고, 아예 처음부터 'ㄴ' 형상을 갖도록 부재를 둘로 나누지 않고 한 몸체로 형성할 수도 있을 것이다.In this case, the horizontal member 100 'and the vertical member 200' may be provided separately from each other, and then may be manufactured as one specimen having a 'b' shape by being mutually coupled or bonded to each other. The member may be formed into a body without dividing the member into two so as to have a shape.

물론, 한 몸체를 갖는 경우에는 성형할 때부터 그렇게 만들어야 하므로 이미 제조된 아크릴과 같은 수단을 서로 붙여 만들 경우와는 다를 수 있다.Of course, if you have a body, since it must be made from the time of molding, it may be different from the case of pasting the means, such as acrylic already prepared.

다만, 여기에서는 구현 가능한 예를 예시적으로 설명할 뿐이며, 본 발명에서는 아크릴과 같은 판을 이용해야 하므로 두 개의 부재를 서로 접합하는 형태가 적당할 것이다.However, only exemplary embodiments are described as examples, and in the present invention, a plate such as acryl should be used, so that two members may be bonded to each other.

아울러, 이러한 변혀예에 있어서도 당연히 표시부(400)를 포함해야 하며, 각장(D)도 길이별로 여러개 제조되어야 함은 물론이다.In addition, in this example of variation, of course, the display unit 400 must be included, and each sheet D must also be manufactured in pieces by length.

이러한 구성으로 이루어진 본 발명은 다음과 같이 사용될 수 있다.The present invention having such a configuration can be used as follows.

앞서 설명한 바와 같은 다수의 선박 제조공정중 필렛 용접시 용접비드를 형성할 때 작업자는 본 발명에 따른 표준 시편을 휴대하고 있다가 용접 대상 모재의 용접비드를 구성하는 각장(D)을 표준 시편과 비교하면서 용접하여 형성한다.When forming a weld bead during fillet welding during many ship manufacturing processes as described above, the operator carries the standard specimen according to the present invention and compares the square length (D) constituting the weld bead of the base material to be welded with the standard specimen. While forming by welding.

즉, 용접시 표준 시편을 옆에 두고 이를 직접 비교함으로써 실시간적으로 현장에서 용접비드 형성시 즉시 교정이 가능하므로 정확하고 우수한 품질의 용접비드를 형성할 수 있게 된다.In other words, by directly comparing the standard specimen to the side when welding, it is possible to immediately correct when forming the weld bead in the field in real time, it is possible to form a weld bead of accurate and excellent quality.

따라서, 용접 불량이 방지되고, 용접 품위가 향상되는 장점을 얻을 수 있게 된다.
Therefore, it is possible to obtain an advantage that welding failure is prevented and welding quality is improved.
