Abstract: The quadcopter system (100) for welding defect detection in pre-engineered buildings features a frame (102) with rotors (104), a mast-mounted GPS (106), a imaging unit (110), a battery (112), and a flight-control stack (114). Supported by extended landing gear (124), a downward payload mount (116) carries three horizontal spray containers (118a,118b,118c): a cleaner, a dye penetrant, and a developer.Three servo actuators (120a,120b,120c) sequentially actuate these containers to perform automated dye penetrant testing. Simultaneously, an onboard AI-based defect detection module (122) processes images captured by the imaging unit (110) to accurately identify and classify critical welding defects, including cracks, porosity, spatter, burn-through, and excess reinforcement, ensuring comprehensive structural quality control.
