ABSTRACT:
A weldable workpiece having a surface deposition including an absorber dye possessing strong absorption and a high extinction coefficient. The dye is deposited at a uniform density and thereby has the capacity to convert inbound radiant energy over about 0.1 J per square millimeter into thermal energy via vibronic relaxation and exothermic decomposition. In optical applications, the workpiece forms welds of high photopic and optical transmission. The improved transmission results from the solvent residues, additives, dyes and by-products being mutually miscible with the workpiece surface. A method for preprocessing the workpiece describes steps for selecting polymers, dyes and vehicles.
