Abstract
A method of accurately applying maskant to a workpiece using one or more scanned laser beams and a maskant delivery device. The method includes the interaction of the laser beams with the maskant material while the material is in transit to, and after it has reached the surface of, the workpiece. Other features of the method include: laser roughening of application surfaces and laser melting of maskant to enhance adhesion of the maskant, laser measurement of maskant edges and correction of detected edge errors, and suppression of maskant ignition by forced ventilation and inert gas environments.
