This patent relates to the use of specialized tools or manufacturing processes in the robotic assembly of manufactured components such as automobile parts. The invention provides a combination assembly tool that is mounted to a conventional robot that selects parts from a tray or other stationary supply and transfers the part to be assembled on a workpiece. The combined tool includes means to: grip the part; laser scan the workpiece; calculate any offsets required for proper positioning within predetermined tolerances; heat plastic part surfaces and workpiece part surfaces simultaneously; and press the heated surfaces together to form a thermal plastic weld joint and impervious fluid seal.

The method described is suitable for thermal plastic welding of plastic gas tanks for automotive applications.
