ABSTRACT:
A method of welding plastic components using an induction weldable plastic material to a wall of a hollow plastic vessel entails providing a metal disk to a first plastic component, providing the first plastic component with a weldable plastic material, inserting the plastic component through a hole in a wall of the hollow plastic vessel, the inserting being from an exterior of the vessel to an interior of the vessel, positioning the first plastic component against or proximate an interior wall of the hollow plastic vessel, orienting an electro-magnet about the exterior of the vessel, orienting an induction coil about the electro-magnet such that the induction coil encircles the electromagnet; energizing the electro-magnet so that the metal disk of the first plastic component is secured against the wall of the vessel, and energizing the induction coil so that the induction weldable plastic material welds to the vessel wall.
