Multiple conductor fluid handling duct for an automobile vehicle |
摘要 |
A fluid handling duct for an automotive vehicle has a channel section having a base and integral, upstanding interior and exterior wall elements and a closure cap which is friction welded to each of the wall elements. The closure can has several V-shaped projections depending therefrom which are sized such that during friction welding according to the method disclosed herein the wall elements contacted by each of the V-shaped projections will be deflected in a direction transverse to the longitudinal axis of the duct whereby the V-shaped projection and a corresponding wall will be held together with a force of deflection having sufficient magnitude to cause welding of the V-shaped projection to the wall when the closure cap is moved relative to the channel section during friction welding.
