Joining structure and method of metal works

A gap is provided at joining faces of a pair of metal works with an uneven shape when the metal works contact one another for joining. An adhesive agent having a chain-reacting curing reaction function is disposed within the gap. The adhesive agent is cured by an autogenously-generated curing reacti...

Beschreibung
Zusammenfassung:	A gap is provided at joining faces of a pair of metal works with an uneven shape when the metal works contact one another for joining. An adhesive agent having a chain-reacting curing reaction function is disposed within the gap. The adhesive agent is cured by an autogenously-generated curing reaction heat caused by an outer energy and an additional heat that is successively generated by the autogenously-generated curing reaction heat within the adhesive agent. A welding portion, where the works contact one another substantially directly, is welded by a laser beam, and the above-described energy for causing the autogenously-generated curing reaction heat for the adhesive agent is provided by the laser beam. Accordingly, a joining structure and method of metal works that can have less limitation in a joining location is provided.
