Abstract
A fitting for use in fusion welding mating thermoplastic components includes a weld bead chamber to capture and conceal a bead formed as a result of the fusion weld. The weld bead chamber integrates the bead into the fitting so that the joined parts have a finished look without mechanical polishing or grinding of the completed piece. A stop ledge included in the weld bead chamber prevents over insertion of a pipe or other component into the fitting. A view window in the fitting permits inspection of the finished bead.
