Pin tool, for friction welding, has a multi-pin geometry to give an effective material compression in the dead zone and the tool can be moved at the required speed

摘要

The pin tool (1), for friction welding, has a multi-pin geometry structure or the pin (2) has at least one radial passage opening. Two symmetrical pins are separated by a gap (9), and each has an edge (10) in the direction of rotation (8) with a cutting action and a blunt edge (11). The radial passage opening has a rectangular opening cross section.
