Abstract

The method involves forming a round or slot-shaped hole (2) in the surface of a pipe section (1) using a rotationally symmetrical conically-tapering tool (4) to form a neck. The work piece is rotated several times around the mid-perpendicular (3) of the hole and the tool is introduced at a small angle to the mid-perpendicular and held against the edge of the hole and fed in and out of the hole at a constant angle, to roll the edge of the hole. An Independent claim is included for a device for implementing the method.
