る。Prior Art When joining panel members, spot welding has conventionally been commonly used, but when joining panel members by spot welding, stress is concentrated in the welded area, making it difficult to maintain sufficient joint strength. Recently, so-called weld bond ink has been proposed, which aims to improve the bonding strength by applying an adhesive to the bonding surface, bonding, and then spot welding. (Japanese Unexamined Patent Publication No. 199675/1983, etc.). According to this weld bonding, the characteristics of adhesion and spot welding can be obtained at the same time, so it is possible to increase the bonding strength.

合強度を低下させる原因となっていた。Problems to be Solved by the Invention However, when joining panel members using weld bonding ink, the generation of dust due to spot welding is unavoidable, and as a result, the adhesive around the welded part is scattered and the desired result is not achieved. Not only is it difficult to obtain bond strength;
There is a problem that the scattered adhesive contaminates the working environment, and the heat generated by spot welding easily deforms the mating surfaces (the adhesion of the joint surfaces decreases, the adhesive peels off, and the desired Furthermore, in order to perform spot welding across the adhesive, it is necessary to increase the pressure of the welding gun, which causes the adhesive to leak during welding. Thermal deterioration occurs, which also causes a reduction in bonding strength.

A thermosetting adhesive having a relatively low viscosity during welding and heat curing is applied to the convex groove side of the space between both panel members formed by the panel member and the other panel member.

ことが可能となる。According to the present invention, there is no adhesive in the spot weld, and therefore not only is the scattering of the adhesive caused by dust generated by spot welding suppressed, but also the adhesive is Since a higher viscosity adhesive is applied on the outside of the applied low viscosity adhesive, it is possible to prevent the low viscosity adhesive from being scattered by dust. In addition, at least one of the panel members includes
Since the convex groove is formed, the rigidity of the mating surfaces is improved, and it is possible to prevent the mating surfaces from being deformed and the adhesion of the mating surfaces from decreasing due to heat applied during welding. Furthermore, since no adhesive is present in the spot weld, there is no need to increase the pressure of the welding gun more than necessary, and therefore the adhesive does not deteriorate thermally during welding. In addition, even if the bonded panel members are held vertically when heating and curing the adhesive, there is a high viscosity adhesive on the outside of the low viscosity adhesive, so the adhesive will not hold properly. It is also possible to effectively prevent water from flowing down. As described above, according to the present invention, it is possible to effectively prevent the scattering of the adhesive, the outflow from the application area, the thermal deterioration of the adhesive, and the decrease in the adhesion of the mating surfaces, thereby contaminating the working environment. It becomes possible to obtain sufficient adhesive strength without

合とを含む。In the present invention, when the two panel members to be joined are put together, the viscosity during welding and heat curing is relative to the convex groove side of the space between the two panel members formed by the convex groove and the other panel member. When a thermosetting adhesive with relatively high viscosity during welding and heat curing is filled on the opposite side of the convex groove of this low viscosity thermosetting adhesive, This includes a case in which different types of thermosetting adhesives having relatively different viscosities are filled, and a case in which the same thermosetting adhesive is filled with the viscosity adjusted as described above.

とにより、強固に接合される。As shown in FIGS. 3 and 4, a convex groove 5 extending in the welding direction and protruding toward the inner panel 3 is formed at the joint portion of the outer panel 4 with the inner panel 3. The space formed by the convex groove 5 formed in the outer panel 4 and the inner panel 3 is filled with thermosetting adhesives 6 and 7. The thermosetting adhesive 7 filled on the outside opening side of the convex groove 5 has a relative viscosity compared to the thermosetting adhesive 6 filled on the side of the convex groove 5. A high adhesive is selected. In this way, after filling the space formed by the convex a5 and the inner panel 3 with thermosetting adhesives 6 and 7 and bonding the inner panel 3 and the outer panel 4, the convex groove 5
Spot welding is applied to the area. 8 shows a nugget of spot welding. The inner panel 3 and outer panel 4 that have been spot welded and joined are heated, and the thermosetting adhesives 6 and 7 are cured. This ensures a strong bond.

り流出することを効果的に防止することができる。As described above, according to this embodiment, the outer panel 4 is formed with the convex groove 5 that protrudes toward the inner panel 3 at the joint with the inner panel 3. As the thermosetting adhesive 7 filled in the opening side, one having a higher viscosity than the thermosetting adhesive 6 filled in the vicinity of the convex groove 5 is selected, and the convex groove 5 and the inner panel 3 are bonded together. Thermosetting adhesive 6.7 is filled into the spaces formed by the above, and then spot welding 8 is carried out only in the convex groove 5.
Since there is no adhesive in the convex groove 5 where spot welding is performed, there is no need to increase the pressure of the welding gun unnecessarily, so the heat applied during welding can create an adhesive. This prevents the adhesive from deteriorating, and even if dust is generated during spot welding, the effect of dust on the adhesive is reduced.
Even when affected by dust, the viscosity of the adhesive 7 filled on the outside of the convex groove 5 is higher than the viscosity 6 of the adhesive filled in the vicinity of the convex groove 5. Even if the adhesive 6 filled in the vicinity of the groove 5 is affected by dust, the high viscosity adhesive 7 on the outside prevents it from scattering, so the adhesive does not scatter. It becomes possible to firmly join the inner panel 3 and the outer pile 4, and the working environment is not contaminated by scattering of adhesive. In addition, since the convex groove 5 is formed on the mating surface of the outer panel 4 and the inner panel 3, the rigidity of the mating surface is improved and the mating surface will not be deformed even if heat is applied during welding. There is no, therefore,
Inner panel 3 and outer panel 4 on mating surfaces
Adhesive 6.7
This allows the inner panel 3 and outer panel 4 to be bonded together with sufficient adhesive strength. Furthermore, after joining the inner panel 3 and outer panel 4, an adhesive 6
．． Even when heating is applied to cure the adhesive 7, the flow of the low-viscosity adhesive 6 is suppressed by the high-viscosity adhesive 7, so the adhesive does not need to hold the joint horizontally. It is possible to effectively prevent leakage.
