Abstract (en)
[origin: WO9701433A1] The present invention comprises articles adapted for use in electro-fusion welding of thermoplastic articles, such as pipes. One embodiment of the invention comprises a length of pipe, or a fitting therefor, having a modified weld interface for its electro-fusion joining to a second pipe or fitting etc. In another form the invention comprises an inermediary element positionable between articles (such as pipes) for their electro-fusion joining. In both forms, the weld interface is typically characterised by being of a thermoplastic material and including at least one filament arrangement, which in turn comprises one or more filaments aligned substantially lengthwise with respect to the weld interface; and wherein the filaments of the filament arrangement are also substantially parallel to the contact face of the weld interface; and further wherein said filaments terminate at terminal portions not forming part of the weld between the articles.
