Abstract
An automated system for preparing weld land areas of panels to be welded to each other is disclosed. Generally, the system of the present invention includes a system for cleaning contaminants from such weld land areas. In one embodiment, the system for cleaning contaminants includes a system for blasting carbon dioxide granules or pellets against the weld land areas. In instances where the panels comprise aluminum, the system may further include a system for removing at least a first layer of aluminum oxide from the weld land areas. In one embodiment, the system for removing includes a system for moving a plurality of sheets of sand paper over the weld land areas. For purposes of moving the panels relative to the system for cleaning contaminants and/or the system for removing at least the first layer of aluminum oxide, the automated system of the present invention may further include a shuttle system for supporting and moving at least the first panel therethrough.
