<p>A method and apparatus are disclosed for dielectric welding together of two thermoplastic flanged parts (56, 58) to form a flangeless, typically thin-walled, thermoplastic shell. A pair of relatively movable, clamping electrodes (32, 34), which define a shell-receiving hollowed space bounded by flange-engaging areas, operate together to create a flangeless weld. The characteristics of the flange-engaging areas, the dielectric field application, the clamping action, and the timing of various operations are all important features. One of the preferred embodiments relates to a double-beveled cutting electrode.</p> |
