の欠陥が生じ易い問題点があった。(3) Problems to be solved by the invention This conventional backing metal (a) is applied between the back surfaces of the upper and lower pillar structural members (b) and (c) as shown in FIGS. 7 and 8. b) Welding (d) between (c) or backing metal (a)
As shown in Figs. 9 and 10, apply the pillar 44t and the lower surface of the first part of the chinese thread (4) and weld together the two parts (e) and (f). (d), but the said backing money (
1k) is a rectangular flat plate, and the space between the two members (b), (C) or (e) and (f) is closed by the backing metal (1k), so that the heat generated during welding is transferred to the backing metal (1k). There is a problem in that the preheating efficiency is poor because it does not go around to the back side of (a), and the jet stream due to the arc energy is convected, which tends to cause defects such as blowholes.
本発明はこれらの問題点を解消した構造簡単な裏当金を
提供することを目的とする。An object of the present invention is to provide a backing metal with a simple structure that solves these problems.
（４）問題点を解決するための手段
この目的を達成すべく本発明は裏当金本体の一端を凹凸
状に形成したことを特徴とする。(4) Means for Solving the Problems In order to achieve this object, the present invention is characterized in that one end of the backing metal body is formed into an uneven shape.
（５）作用

過して溶接欠陥がなくなる。(5) Action: Place one end of the backing metal on one of the structural members to be welded, fix the backing metal to the other structural member with a dot, etc., and weld the two structural members together. The heat generated by welding passes through the uneven concave portion at one end of the backing metal and reaches the back side of the backing metal, resulting in good preheating efficiency, and the jet stream due to arc energy passes through the concave portion without convection. Welding defects are eliminated.
（６）実施例 本発明の１実施例を第１図に従って説明する。(6) Examples One embodiment of the present invention will be described with reference to FIG.
（１）は裏当金を示し、その本体（１ａ）は長方形状の
鋼板からなりその一端に複数の凹部（２ａ）と凸部（２

接欠陥を生じない。Thus, as shown in Fig. 2, the column structural member (3) and the beam structural member (
4), place one end of the backing metal (1) against the side surface of the column structural member (3) and place the backing metal (1) on the lower surface of one end of the beam structural member (4). Also, when welding the upper and lower column structural members (5) and (6) as shown in Figures 3 and 4, one end of the backing metal (1) is brought into contact with the top of the lower column structural member (6). Then, the backing metal (1) was attached to the upper column structural member (5), and the upper column structural member (7) and top plate (8) were fixed as shown in Figures 5 and 6. When welding the lower column structural member (9), one end of the backing metal (1) is brought into contact with the top surface of the top plate (8) and the backing metal (1) is welded.
are dotted on the side surface of the upper column structural member (7), and welded between the two members. During these weldings, the heat passes through the recess (2a) of the backing metal (1) and reaches the back side of the back metal, so preheating efficiency is good, and the jet stream due to arc energy passes through the recess (2a) without convection. Therefore, no welding defects occur.

ある等の効果を有する。(7) Effects of the Invention As described above, according to the backing metal of the present invention, one end of the backing metal main body is formed in an uneven shape, so one end of the backing metal is applied to one of the structural members to be welded. When the backing metal is fixed to the other structural member using dots or the like and the two structural members are welded, the heat generated by welding passes through the uneven recess at one end of the backing metal, and then the backing metal is welded to the other structural member. The jet airflow caused by the arc energy passes through the recessed part without convection, eliminating welding defects.Furthermore, there is no blowout caused by closed welding, and an equal pressure state can be maintained.
Further, it has effects such as being particularly effective for arc welding using a gas shield method.
