Junction of three object that uses the friction stir processing technology

摘要

Friction stir tool for performing friction stir riveting with a pin consumable partially is provided, this pin, and a cutting edge at its bottom surface, the tool overlaps with the second material After being rotated at a first speed to allow to cut the pins in the material of the first pin is cut to a sufficient depth, the rotation speed of the tool can be increased, and consumable thereby This allows for plasticizing the material of the second material, and then the tool is rapidly decelerated to a stop, can be diffusion bond between the material of the second material, and the pin, the first pin, the first become.
