Description of the Related Art As shown in FIGS. 2 and 3, a structural adhesive 4 is used when attaching a hood inner panel 3 to a hood outer panel 2 in the manufacturing process of an automobile 1. Conventionally, the structural adhesive 4 has been used in the form of a liquid or a paste. When using such a liquid or paste structural adhesive, generally the adhesive is pumped by a pressure pump and is discharged from a nozzle of a dispensing device to apply it to the surface of the object to be bonded, such as the hood inner panel 3. The object coated with the adhesive is attached to a required portion of the vehicle, such as the hood outer panel 2.

発明の詳細な説明
以下にこの発明の自動車車体における接着作業方法を第
１図を参照してさらに具体的に説明する。DETAILED DESCRIPTION OF THE INVENTION The method for bonding an automobile body according to the present invention will be explained in more detail below with reference to FIG.
尚、第１図にはフードアウタパネル２に取付けるフード
インナパネル３に接着剤を塗布する場合を示す。Incidentally, FIG. 1 shows the case where adhesive is applied to the hood inner panel 3 to be attached to the hood outer panel 2.
第１図に示すようにこの発明では先ず、フードインナパ

７としては、例えば市販されている住友３〜１製構造接
着剤ＸＤ−３４９９を用いる。Next, in the present invention, the solid adhesive 7 is pressed and melted onto the heated portion 5 by the frequency heating coil 6. As the solid adhesive 7, for example, a commercially available structural adhesive XD-3499 manufactured by Sumitomo 3-1 is used.
また、接着剤が溶融塗布される部分の幅は、固形接着剤
７の断面寸法により決定され、換言すれば固形接着剤７
の断面形状により接着剤の塗布幅は自由に粘度良く設定
できる。Further, the width of the part where the adhesive is melted and applied is determined by the cross-sectional dimension of the solid adhesive 7.
Depending on the cross-sectional shape of the adhesive, the application width of the adhesive can be freely set with a good viscosity.
さらに、固形接着剤７を適宜に選択し、高周波加熱コイ

後のアウタパネル２とインナパネル３の接着部分には充
分な接着状態が得られる。In this invention, the inner panel 3 is attached to the outer panel 2 at the portion 5 where the solid adhesive 7 is melt-applied as described above.
Adhesion is performed. Since the melt-applied adhesive is in a heated state, the bonding surface of the inner panel 3 is not completely cleaned, and even if, for example, oil or fat is attached, the outer panel 2 and inner panel 3 after bonding may not be completely cleaned. A sufficient adhesive state can be obtained at the adhesive part.

生じる危険もなくなる。In addition, the adhesive melted and applied to the inner panel 3 solidifies during the process of attaching the inner panel 3 to the outer panel 2, so even if a worker or other person comes into contact with the adhesive at the joint, the adhesive layer will remain intact. There will be no damage,
There is no possibility that the flaps used to press the adhesive parts of the outer panel 2 and the inner panel 3 together will get dirty. Conversely, there is no risk of the adhesive adhering to the worker's skin and causing skin rashes or the like.
