（産業上の利用分野）
本考案は各種の構造物の片面溶接に用いる裏当
材に関する。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a backing material used for single-sided welding of various structures.
（従来技術とその問題点）
造船、建築、橋梁等に於て、溶接によつて構造
物を造る際に、両面溶接が不可能な場合が多い。
このために又は溶接工程の手間を省く目的で、片
面溶接が広く実施されている。この片面溶接には
裏波ビードを形成させるために、裏当材が使用さ
れるが、簡易片面溶接裏当材として、軽量短尺状
の固形裏当材が多用されている。(Prior art and its problems) When building structures by welding in shipbuilding, architecture, bridges, etc., it is often impossible to weld both sides.
For this reason or to save time in the welding process, single-sided welding is widely practiced. A backing material is used in this single-sided welding to form an underwave bead, and a lightweight, short solid backing material is often used as a simple single-sided welding backing material.
ところが従来の片面溶接用裏当材は、裏当材を
取り付けるさい、被溶接材開先裏面の適正位置に
正確に合せにくく、特に開先が曲つている場合に
はずれてしまうことがあり、この状態で溶接を施
すと、溶融スラグの流れ落ち等が発生し、良好な
裏波ビートを期待できなかつた。 However, when attaching the conventional backing material for single-sided welding, it is difficult to accurately align it to the proper position on the back side of the groove of the welded material, and it may come off, especially if the groove is curved. If welding was carried out under such conditions, molten slag would flow down, and a good Uranami beat could not be expected.
（考案の目的）
本考案はこのような従来技術の欠点を解消し、
正確かつ容易に開先裏面に取り付けが可能で、あ
わせて製造が容易な片面溶接用裏当材を提供する
ことが目的とする。(Purpose of the invention) The invention solves the drawbacks of the conventional technology,
It is an object of the present invention to provide a backing material for single-sided welding that can be accurately and easily attached to the back side of a groove and is also easy to manufacture.
（問題点を解決するための手段・作用）
この目的を達成する本考案の要旨とするところ

該下面に裏当材取付用テープを貼付してなる片面
溶接用裏当材にある。以下本考案を図面に示す具
体例により説明する。(Means/effects for solving the problem) The gist of the present invention to achieve this purpose is to form a linear or dot-like concave or convex portion in the longitudinal direction at the center in the width direction using a mold at least on the lower surface. This backing material for single-sided welding is made by continuously arranging a plurality of integrally molded short tile-like solid materials and pasting a tape for attaching the backing material to the lower surface. The present invention will be explained below using specific examples shown in the drawings.
第１図ａは本考案の具体例の上側全体斜視図、
同図ｂは下側全体斜視図、第２図はその使用状態

広幅に構成される。 FIG. 1a is an overall upper perspective view of a specific example of the present invention;
FIG. 2b is a perspective view of the entire lower side, and FIG. 2 is a diagram showing the state in which it is used. 1 is a short solid ceramic heat-resistant tile having a rectangular cross section, and a slag pocket is provided in the longitudinal direction of the center of the upper surface (the surface in contact with the groove). Reference numeral 2 denotes a backing material attachment tape made of a flexible heat-resistant material, such as A foil, for attaching the solid material 1 to the back surface of the groove of the material to be welded, and is configured to be wider than the solid material 1.
該テープ２は一面に接着材を塗布され、その塗
布面中央長手方向に、短尺の固形材１を複数個

プ３を貼付している。 The tape 2 is coated with an adhesive on one side, and a plurality of short solid materials 1 (six pieces in FIG. 1) are successively pasted in the longitudinal direction of the center of the coated surface, and backing materials are attached to both ends in the longitudinal direction. A peeling tape 3 is attached that is removed when in use.
なお裏当材取付用テープに塗布する接着剤（有

剤層の厚さを100μm以下におさえることが好まし
い。 Note that if too much adhesive (mainly organic) is applied to the backing material mounting tape, it will thermally decompose during welding (700 to 800°C on the back side of the solid material), producing H 2 , Since gases such as CO and N 2 are generated and defects such as bits and blowholes occur in the welded part, it is preferable to keep the thickness of the adhesive layer to 100 μm or less.
取付用テープとしてＡ箔を用いた場合は、熱
の放散効果の点から厚い方がよく、少なくとも接
着剤の厚さ以上の厚さとする。例えばＡ箔厚：
90μm、接着剤層厚：50μmとする。 When A foil is used as the mounting tape, the thicker the better from the viewpoint of heat dissipation effect, and the thickness should be at least as thick as the adhesive. For example, A foil thickness:
90μm, adhesive layer thickness: 50μm.
本考案の裏当材では、さらに個々の固形材１の

が直線状にあるように固形材１を並べている。 In the backing material of the present invention, a linear convex portion is further formed in the widthwise center of the lower surface of each solid material 1 (the surface on the backing material mounting tape 2 side) and in the longitudinal direction (direction along the groove). 4, and a point-like recess 5 is formed at the center of the upper surface of the solid material 1 in the width direction, and the protrusion 4 and the recess 5
The solid materials 1 are arranged so that they are in a straight line.

下側では、裏当材取付用テープ２の線状の凸部４
（この凸部４′は、固形材１の下面凸部４により形

On the lower side, the linear convex portion 4 of the tape 2 for attaching the backing material
(This protrusion 4' is formed by the protrusion 4 on the lower surface of the solid material 1) appears (FIG. 1b).

便利である。 In the figure, 6 indicates a ventilation hole for heat dissipation. If necessary, wires, strings, etc. can be passed through the hole 6 to integrate each fixed type 1, and after welding is completed, the backing material can be attached to the welded material. When removing from 8, solid material 1 is attached to mounting tape 2.
This is convenient because it prevents the objects from falling off and becoming scattered.
このような本考案の裏当材を使用する場合は、
第２図に示すように、裏当材の下側の凸部ライン
又は上側の凹部を、開先７裏面に当てればよく、
裏当材の位置合せ作業が、正確かつ簡便に行なう
ことができる。８は被溶接材を示す。 When using the backing material of this invention,
As shown in FIG. 2, the lower convex line or the upper concave part of the backing material may be applied to the back surface of the groove 7,
The alignment work of the backing material can be performed accurately and easily. 8 indicates the material to be welded.
上記の具体例では、固形材の下面に線状の凸部
上面に点状の凹部を形成したが、これに限ること
なく、下面凹部、上面凸部でもよいし、線状とす

のような凹部又は凸部を、固形材の少くとも下面
にすればよい。 In the above specific example, a linear convex part is formed on the lower surface of the solid material, and a dotted concave part is formed on the upper surface of the solid material. The decision will be made as appropriate. In short, such recesses or protrusions may be formed at least on the lower surface of the solid material.
さらに本考案の裏当材は、きわめて簡単に製造
できる利点もある。すなわち固形材成形用の型に
凹部、凸部を形成しておけば、固形材成形と同時
に求める固形材の凹部、凸部を形成するための作
業工程を別途設ける必要はない。 Furthermore, the backing material of the present invention has the advantage of being extremely easy to manufacture. That is, if the recesses and projections are formed in the mold for molding the solid material, there is no need to provide a separate work process for forming the desired recesses and projections of the solid material simultaneously with the molding of the solid material.
又Ａ箔等の裏当材取付用テープに固形材を貼
付する際に、固形材の凹部、凸部部分に対応する
テープ部分を押えれば、当該部分が塑成変形し
て、容易に裏当材取付用テープに凹部又は凸部を
形成できるから問題はない。 Also, when attaching a solid material to the backing material mounting tape such as A-foil, if you press the part of the tape that corresponds to the concave or convex parts of the solid material, that part will be plastically deformed and the backing material will be easily attached. There is no problem because recesses or protrusions can be formed in the tape for attaching the material.
