A dielectric welding apparatus for welding a plastic sleeve contains a solid state radio frequency generator linked via a matching network to a welding tool. The tool ( ) includes a frame ( ) with a handle ( ), the frame defining a slot in which are opposed welding electrodes ( ), the slot being open at one end and at the other end communicating with a wider aperture ( ). A pneumatic cylinder ( ) can be actuated to urge the electrodes together, both the cylinder ( ) and the RF generator ( ) being activated by a trigger ( ) on the tool ( ). The electrodes are coated with an electrically insulating material that is not dielectrically heated, and are readily removable, so they can be replaced, for example when the electrically insulating coating becomes worn.
