Method for metal and alloy joining using bulk friction stir welding

摘要

A method comprising a bulk processing technique for joining different metals and alloys using friction stir welding, wherein a block of a first material has at least two apertures disposed therein, wherein at least a first tube and a second tube are disposed in the at least two apertures, wherein friction stir welding is performed to join the block, the first tube and the second tube together in a solid state form, and the resulting workpiece is then machined to produce the completed joint.
