Description of the Related Art Generally, in the weld bond joining method, resistance spot welding is performed on a plurality of plates through an adhesive, and then heat treatment is performed under the condition that the adhesive is hardened to harden the adhesive to obtain welding strength and adhesion. The strength is intended to obtain the overall bonding strength. For example, when this weld bond joining method is applied to joining a body panel of an automobile, after resistance spot welding of the panel, it passes through several steps,
Finally, the paint is baked, and the adhesive is simultaneously cured during the heating of the paint to obtain a combined bonding strength of adhesive bonding and welding bonding. Even before the adhesive is heat-treated and cured, as described above, various processes are performed through several steps, so that a certain sufficient joint strength by spot welding is required. Further, even after the adhesive is heat-treated and cured, even if the bonded portion is peeled off due to aging or for some reason, it is necessary to secure a certain sufficient joint strength at the spot welded portion.

前の十分な溶接強度を得ることは困難であった。However, in the conventional weld-bonding method, due to the intervention of the adhesive agent on the above-mentioned plurality of plates, during resistance spot welding, the electrical conductivity becomes poor and the heat does not occur, and the resistance heat is absorbed by the adhesive agent. Since the material to be welded does not have a sufficient amount of heat until it melts, it causes poor melting, and at the same time, the internal quality of the nugget is inferior to that of general resistance spot welding when no adhesive is used. There was a problem that sufficient welding strength before heat curing could not be obtained. On the other hand, if the current value is increased so that the nugget can be sufficiently produced, the electrode and the material to be welded will be welded or blown, resulting in a problem that sufficient welding strength cannot be obtained. Note that the bonding with an adhesive is performed by heat treatment and curing to obtain high strength, and the adhesive strength itself before heat treatment and curing is naturally low. As a related technique, a proposal of adding various metal fibers or the like to an adhesive for the purpose of improving the weld bond strength is disclosed in JP-A-60-173075 and JP-A-6-17675.

Silica, etc.), some plasticizers, solvents, pigments, etc. may be added in appropriate amounts. Further, the reason why the particle size in the case of powder is 10 μm or less is that it adheres to improve conductivity when pressure is applied by resistance spot welding, and if it exceeds 10 μm, not only the conductivity is deteriorated, There is a risk of excessive heat generation during welding. Further, it is difficult to mix them in manufacturing the adhesive.

The reason why the size is 5 μm or more and the size is 30 μm or less is that a thickness of 0.5 μm or more is required to obtain a predetermined shape, and if the thickness is less than 0.5 μm, the effect of the additive cannot be obtained.
This is because the actual manufacturing is difficult. The size is 30 μm
If it exceeds, the distribution in the adhesive becomes uneven, and
This is because the cost for manufacturing the adhesive increases. The reason why the amount of the additive added is 1 to 15% in terms of Vol% is that the effect of the additive does not appear if it is less than 1%, and if it exceeds 15%, the viscosity of the adhesive decreases, the weight increases, and the adhesion increases. This is because the distribution in the agent becomes non-uniform and excessive heat is generated during resistance spot welding, which may cause explosion and the like.
