  • Method and apparatus for creating channels in workpieces
    Patent number: 11020817
    Abstract: A friction stir channelling tool comprises a probe (2) for inserting into a workpiece or workpieces. The probe (2) extends from, and is rotatably mounted in, a bore (14) of a shoulder (3), the probe surface being formed so as to cause plasticised workpiece material to be moved towards the shoulder and into the bore of the shoulder upon rotation of the probe while the shoulder is in contact with the workpiece. The shoulder (3) has at least one vent (4) extending from outside the shoulder to the bore (14) whereby the plasticised material can exit the bore through the vent.
