Abstract: A system and method for reducing the accumulation of weld spatter on welded automotive body panels and the adherence of weld spatter thereto including a compressed air supply, a liquid supply, a pump, at least one control valve, at least one regulator, a controller, and a material handling mechanism. The method includes positioning a body panel with respect to one or more spray nozzle assemblies, applying a controlled spray of anti-spatter liquid to the body panel surfaces prior to spot welding of the panel into a panel assembly, and shutting off the system pressure when the process is complete. The method also includes controlling multiple spray nozzle assemblies using a single pump, and rinsing the panels' surfaces after welding.
