OPTICAL DEVICE AND METHOD FOR TRAINING MACHINE LEARNING MODEL FOR WELDING DEFECT INSPECTION

Abstract: an optical device may include an infrared detection unit that detects heat generated at a weldment during welding, a visible light detection unit that detects plasma generated at the weldment and a spectroscopic unit that detects wavelength-specific luminosity at the weldment, wherein the optical device determines an occurrence of welding defects at the weldment based on the detected heat, the detected plasma, and/or the detected wavelength-specific luminosity of the weldment.
