Abstract

Thin-walled thermoplastic bodies, e.g. container bodies and their bottoms, or a container mouth section and a lid which have rotationally symmetrical connecting parts, are friction-welded by partially forming the one object with: (a) an annular end having a rotational flange at a distance from the front face; (b) a lateral flange surface facing the other object, which forms the primary welding surface; (c) another lateral flange face at the rear which serves as a contact area for a holding tool during welding; and (d) flange edge surfaces which constitute a secondary welding surface. The other object is partially formed with (a) surfaces which co-operate with the surfaces at the annular end of the first object to leave cavities for receiving and retaining material produced during welding; (b) a surface which fits the primary welding surface, against which it is pressed during welding, and (c) an annular surface that fits the flange edge sections to take up material deposited during welding, which is prevented from escaping by the holding tool.
