Abstract
In a joining method for manufacturing a rotor blade by joining a plurality of members, the members are pressed so as to exert a predetermined pressure on the bonding interface. A pulse voltage is applied to the members to pass electric current therethrough, and the joint portion is heated by resistance heating generated at the bonding interface and in the bulk of the members to cause diffusion bonding and thereby to join the members to each other. With this method, good joining can be achieved without substantially changing the crystal structure and mechanical properties of the base metals.
