自溶接方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method of fillet welding damping steel plates, and more specifically, the corner portions of a damping steel plate and an ordinary steel plate are welded with staggered intermittent fillets by arc welding. This invention relates to a method of corner welding of damping steel plates as if welding.

動車用エンジンのカバー、変圧器やモータのカバーなど
に使用されている。Vibration-damping steel plates, which have a structure in which a viscoelastic resin layer is sandwiched between two steel plates, are used as energy damping materials for vibration and noise, such as automobile engine covers, transformer and motor covers, etc. .
そして、最近になつて、船舶や列車などの居住区の内壁

と普通鋼板とを接合するアーク溶接によるすみ肉溶接が
できることが要求されている。Recently, damping steel plates are being used as interior wall materials for living quarters such as ships and trains. In order to use damping steel plates as the inner wall material, unlike conventional engine covers and motor covers that are assembled by spot welding after press forming, vibration damping wAFi,
It is required to be able to perform fillet welding by arc welding to join ordinary steel plates.
すなわち、居住区の内壁材として剛性を高めるために、
制振鋼板に補強部材（リプ）を取り付ける必要がある。In other words, to increase rigidity as an interior wall material for living areas,
It is necessary to attach reinforcing members (rips) to the damping steel plate.

接着剤方式などが考えられるが、ボルト締め方式では取
り付けのための孔あけ加工や取り付は作業に手間がかか

る。Possible methods for attaching this reinforcing member include bolt tightening and adhesive methods; however, with the bolt tightening method, drilling and installation are time-consuming, and with the adhesive method, it is time-consuming. There are concerns about the reliability of the adhesive strength.
このため、最も簡便で実用的であるアーク溶接による補
強部材の取り付けが強く望まれている。For this reason, it is strongly desired to attach the reinforcing member by arc welding, which is the simplest and most practical method.
そして、内壁材である制振鋼板と補強部材である普通鋼
板との継手形状は、Ｔ形のすみ内継手となっている。The shape of the joint between the damping steel plate, which is the inner wall material, and the ordinary steel plate, which is the reinforcing member, is a T-shaped corner joint.
そこで、上記のような要請に応えるために、発明者らは
、制振調板（内壁材）と普通鋼板（補強部材）とを用い
てアーク溶接によるすみ肉溶接実験を実施したところ、
以下に説明する問題点があることがわかった。Therefore, in order to meet the above demands, the inventors conducted a fillet welding experiment using arc welding using a vibration damping plate (inner wall material) and an ordinary steel plate (reinforcing member).
It was found that there were problems as explained below.
はじめに、内壁材である制振鋼板と補強部材である普通
鋼板とにより形成される継手形状について説明すると、
この溶接される継手は、第２図に示すように、制振鋼板
（１）の表面に普通鋼板（２）の端面が当接され、この
制振鋼板（１）と普通鋼板（２）とのコーナー部を溶接
線とするＴ形のすみ肉継手である。なお、１枚の制振鋼
板（１）には、所定の間隔を隔てて複数の普通鋼板（２
）が配置されている。また、制振鋼Ｆｉ（１）の樹脂層
の厚みは、たとえば、５０〜１００μｍ程度である。First, we will explain the joint shape formed by the damping steel plate, which is the inner wall material, and the ordinary steel plate, which is the reinforcing member.
As shown in Figure 2, this welded joint has the end face of a normal steel plate (2) in contact with the surface of a damping steel plate (1), and the damping steel plate (1) and the normal steel plate (2) are connected together. It is a T-shaped fillet joint with the corner part as the weld line. In addition, one damping steel plate (1) includes a plurality of ordinary steel plates (2
) are placed. Further, the thickness of the resin layer of the damping steel Fi(1) is, for example, about 50 to 100 μm.
そして、このように形成されたすみ肉継手に対して、片
側のコーナー部をその全長にわたってすみ肉溶接し、次
に、普通鋼板（２）を挟むその反対側の溶接線を全長に
わたってすみ肉溶接する両側連続すみ肉溶接を実施した
。Then, for the fillet joint formed in this way, the corner part on one side is fillet welded over its entire length, and then the weld line on the opposite side sandwiching the ordinary steel plate (2) is fillet welded over its entire length. Continuous fillet welding on both sides was performed.
その結果、第３図に示すように、制振鋼板（１）を形成

剥離した。すなわち、粘弾性樹脂層を挟む２枚の鋼板が
引き離されて２枚の鋼板の間に隙間ができるという問題
が生じた。そして、当然のことながら、剥離の生じた制
振鋼板（１）は、振動、騒音のエネルギー減衰材として
の機能を失って内壁材として使用できない。As a result, as shown in FIG. 3, the two steel plates forming the damping steel plate (1) peeled off along the corner near the weld bead. That is, a problem occurred in that the two steel plates sandwiching the viscoelastic resin layer were separated, creating a gap between the two steel plates. Naturally, the damping steel plate (1) in which peeling has occurred loses its function as an energy damping material for vibration and noise, and cannot be used as an inner wall material.

In addition, in Comparative Example 2, the shrinkage stress and heat amount are smaller than in Comparative Example 1, but they tend to concentrate on one side of the corner, so the damping steel plate (1) peels off along the corner after welding is completed. . Furthermore, in Comparative Example 3, the shrinkage stress and the amount of heat increased as in Comparative Example 1, and the damping steel plate (1) peeled off along the corner portion during the second staggered welding.

ことが好ましい。In contrast, in the corner welding method according to the present invention, the shrinkage stress generated in the damping steel plate (+) due to the contraction of the weld metal and the amount of heat for heating the viscoelastic resin layer are applied to the ordinary steel plate (2). By distributing it intermittently along the corner portions on both sides, it was possible to prevent the damping steel plate (1) from peeling off. In this staggered intermittent fillet welding, the length of each weld bead (3) is preferably about 25% or less of the length of the fillet joint.
