Document Type and Number:
Japanese Patent JP4924143
Kind Code:
B2
Abstract:
A gap 3 is provided at joining faces 1a , 2a of a pair of metal works 1 , 2 with an uneven shape when the metal works contact one another for joining. An adhesive agent 4 having a chain-reacting curing reaction function is disposed within the gap 3 . The adhesive agent 4 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 4 . A welding portion 5 , where the works 1 , 2 contact one another substantially directly, is welded by a laser beam 31 , and the above-described energy for causing the autogenously-generated curing reaction heat for the adhesive agent 4 is provided by the laser beam 31 . Accordingly, a joining structure and method of metal works that can has less limitation in a joining location is provided.
