本発明は一対の鋼板の間に樹脂層を介在させてなる制振
積層鋼板に対してスタッドボルトを溶接する方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for welding a stud bolt to a vibration-damping laminated steel plate formed by interposing a resin layer between a pair of steel plates.
一般に、振動エネルギを熱に変換し消滅させる作用を持

ロンなどの樹脂層を介在させてなる積層鋼板が知られて
いる。Generally, a laminated steel plate made of two steel plates with a resin layer such as rubber or nylon interposed between them is known as a vibration-damping laminated steel plate that has the function of converting vibration energy into heat and extinguishing it.
この積層鋼板にスタッドボルトやＴスタッドなどのスタ

どの高分子化合物製品の部材が介在しているため困難で
あった。It has been difficult to weld stud pieces such as stud bolts and T-studs to this laminated steel plate because a member made of a polymer compound product such as rubber or nylon is interposed in between.
この問題を解決する手段としては、特開昭６１−１４１

ッドピースを溶接する方法が公知である。As a means to solve this problem, Japanese Patent Application Laid-Open No. 61-141
As disclosed in Japanese Patent No. 372, upper and lower steel plates forming a laminated steel plate are spot welded using a short circuit component to form a nugget, and then stud welding is performed on this nugget after making it look like a single plate. A method of welding the stud pieces is known.

報によって開示されたように、前記提案と同様に積ＪＩ
Ｆｍ板を形成する上下の鋼板をスポット溶接した後、こ
のスポット溶接部位に部品をプロジェクション溶接する
方法も公知である。In addition, as proposed by the applicant and disclosed in Japanese Patent Application Laid-open No. 108181/1981, similar to the above proposal, product JI
A method is also known in which after spot welding the upper and lower steel plates forming the Fm plate, parts are projection welded to the spot welded areas.
しかしながら、前記従来技術によると積層鋼板の上下二
層の鋼板を一枚のようにしてスタッドピースなどの部品
を全層溶着させることはできるが。However, according to the prior art, parts such as stud pieces can be welded to the upper and lower two layers of the laminated steel plate as one sheet.
スポット溶接とスタッド溶接の２工程が必要となり、し
かもスポット溶接位置を正確に確保してスタッド溶接を
行なわなければならないという問題があった。Two processes, spot welding and stud welding, are required, and there is a problem in that the spot welding position must be accurately secured to perform stud welding.
しかもスタッド溶接によって溶接部周辺にスス状の酸化
物が付着し、このため錆が発生しやすいという問題もあ
った。Moreover, stud welding causes soot-like oxides to adhere to the periphery of the welded part, which causes rust to easily occur.
一方、プロジェクション溶接によってウェルドボルトを
積層板に溶接する場合、通常のウェルドボルトはプロジ
ェクション部が３箇所乃至４箇所あり、加圧力は２５０

どのばらつきにより、プロジェクション部全点は表皮鋼
板とは圧接するが、上下の鋼板と全点ナゲツトを形成さ
せ溶着させることが困難であるという問題があった。On the other hand, when welding a weld bolt to a laminate plate by projection welding, a normal weld bolt has three or four projection parts, and the pressing force is 250.
Kgf to 350 Kgf is required, and due to variations in the flatness of the electrode surface, the difference in height of the projection part, and the surface precision of the steel plate, all projection parts are in pressure contact with the skin steel plate, but all points are in pressure contact with the upper and lower steel plates. There was a problem in that it was difficult to form and weld point nuggets.
本発明は上記事情に鑑みてなされたもので、割振積層板
にスタッドボルトを１工程で完全に溶接することができ
、しかも錆の発生を防止することのできる積層鋼板への
スタッドボルト溶接方法を提供することを目的とする。The present invention has been made in view of the above circumstances, and provides a method for welding stud bolts to laminated steel plates, which allows stud bolts to be completely welded to distributed laminated plates in one step, and which also prevents the occurrence of rust. The purpose is to provide.
本発明は上記の目的を達成するために、１対の鋼板の間

一方の表面に、１対の電極のうち一方の電極に保持され
１個のプロジェクション部を有するスタッドボルトを該

の他方の表面に前記１対の電極のうち他方の電極を当接
させ、加圧通電することにより前記積層板に前記スタッ
ドボルトをスポット溶接するようにしたものである。In order to achieve the above object, the present invention provides a laminated steel plate in which a resin layer is interposed between a pair of steel plates. A stud bolt that is held and has one projection part is brought into contact with the projection part, and the other electrode of the pair of electrodes is brought into contact with the other surface of the pair of steel plates, and energization is applied under pressure. By doing so, the stud bolt is spot welded to the laminate.
上記の方法によると、プロジェクション部が１点である
ため電流はこの１点を流れ、プロジェクション部と鋼板
表皮との間は圧接により、また上下の鋼板間はナゲツト
により溶着される。According to the above method, since there is only one projection part, current flows through this one point, and the projection part and the steel plate skin are welded by pressure contact, and the upper and lower steel plates are welded by nugget.
この結果１工程で積層板の板厚全体に対して十分な溶接
強度を持ってスタッドボルトを溶接することができる。As a result, stud bolts can be welded with sufficient welding strength over the entire thickness of the laminate in one process.
しかも、スタッドボルトを使用することにより小さい加
圧力により溶接強度を保証することができ、さらにスタ
ッドボルト溶接ではなくスポット溶接であるので、錆の
原因となるスマットの発生もない。Moreover, by using stud bolts, welding strength can be guaranteed with a small pressing force, and since spot welding is used instead of stud bolt welding, smut that causes rust does not occur.

kgf to 350 kgf was required, but by using stud bolt 5 it can be reduced to 75 kgf to 150 kgf.
sufficient welding strength can be obtained.
さらにまたスタッド溶接でなくスポット溶接によるもの
であるので、スマットは発生せず錆の発生を防ぐことが
