Abstract

A method for connecting a plastic workpiece to a further workpiece. The method includes inserting a pin on the plastic workpiece through a through-opening in the further workpiece and abutting the first and second workpieces against one another. A friction tool, which has a clamping ring and a friction pin, is engaged to the pin and the friction pin is rotated so that frictional heat produced by friction between the friction pin and the pin brings the pin into a plastic state. The rotating friction pin is moved parallel to the axis of rotation toward the working surface so that the pin is plastically deformed.
