摘要： Friction-weld assemblies and methods of spin-welding are provided, where the components being joined are polymeric components. Designs provided for the polymeric components enable the use of relatively low speeds and pressures to achieve superior friction weld joints between the components. Further, large surface area polymeric components can be successfully friction welded with such designs. In certain variations, at least one polymeric component has a weld surface with a plurality of surface features that are concave (e.g., grooves) or convex. In other variations, the first component in the weld region has a distinct non-complementary shape from the second component, thus creating a progressive advancing weld line that avoids high temperatures that might incur damage to the polymeric component and weld joint. Such component designs additionally provide for improved flash management at the weld joint.
