Abstract
A fusion-welded thermoplastic assembly and a method of fabricating the same includes first and second thermoplastic members fusion-welded together using a third thermoplastic fusion element. The first and second thermoplastic members and the thermoplastic fusion element are heated to a molten state using an infrared heater, and the molten fusion element is fused to each of the first and second thermoplastic elements. Prior to being connected by the fusion element, the first and second thermoplastic members are either brought into contact with one another or is held in such a way that they can be connected to each other using the third thermoplastic fusion element.
