Robotic System Would Inspect Tubes And Fillets

Proposed robotic system inspects arrays of brazed tubes being fabricated for use in heat exchangers and similar objects. Arrays contain coolant tubes mounted in nozzle of main engine of Space Shuttle. Other versions used to inspect components of terrestrial heat exchangers for powerplants, vehicles, and refrigeration equipment. Inspection system provides for automated, complete, objective, and efficient inspection of arrays of coolant tubes. Computer executing image-processing algorithms extracts profiles of tubes and braze fillets and identifies flaws.
