Friction stir welding
Friction stir welding is an interesting development of earlier friction welding methods.
The two parts of the workpiece are clamped in a butt joint against a solid support.
Welding is carried out with a tool similar to a milling cutter, but with the difference that
no metal is actually cut: instead, the friction of the rotating tool against the workpiece is
sufficient to soften the metal without actually melting it. A collar on the tool prevents the
softened metal from being displaced upwards, with the result that both the underside and
top of the joint are very smooth
