| 摘要 |
The invention relates to a friction weld joint for joining components made of a thermoplastic synthetic material, and a method for the production thereof. The friction weld joint is characterised in that at least one of the components (1) to be joined comprises at least one elastic sealing lip (4, 7) which co-operates with a corresponding component (2) in such a way that a cavity (18, 19) is formed between the components (1, 2) to be joined. During or after the welding process detached welding particles are retained in said cavity. A simple and cost-effective friction welding joint of parts made of thermoplastic synthetic material is thereby created, the ejection of chips, especially inside a hollow body composed of various parts, being avoided in a highly reliable manner. |
