Method for hot-gas welding of plastic parts, involves pressing regions of plastic parts against each other after heating at welding temperature, and providing regions with profile for increasing surface of respective plastic parts

摘要

The method involves welding plastic parts with one another, and pressing regions of the plastic parts against each other after heating at welding temperature. The regions are provided with a profile (4), which increases a surface of the respective plastic parts. The profile is formed by ribs running parallel to each other, where a cross section of the profile is outwardly tapered and run outwardly. A connecting flange (1) of a plastic housing (2) is provided at a flange surface (3) with the profile, where the flange surface is provided for a welded joint with a corresponding counter flange.
